IT CHANGE MANAGEMENT PROCESSES AUDIT THE EFFECTIVENESS OF IT CHANGE
MANAGEMENT PROCESSES IN ENSURING CONTROLLED AND AUTHORIZED CHANGES
TO SYSTEMS
1. Question: During an audit of IT change management processes, it was found that out of 100 changes
implemented, 15 were not adequately documented according to regulatory standards. What is the percentage
of changes that were not properly documented?
Solution: To find the percentage of changes that were not properly documented, we need to calculate
the ratio of changes not properly documented to the total number of changes, then multiply by 100 to get
the percentage.
Percentage = (Number of changes not properly documented / Total number of changes) x 100
Percentage = (15 / 100) x 100 Percentage = 15
Therefore, the percentage of changes that were not properly documented during the audit is 15
2. Question: During an audit of IT change management processes, it was found that unauthorized
changes had impacted system stability. If the stability percentage of the system was initially at 95
Solution: To calculate the impact of unauthorized changes on system stability in terms of percentage
decrease, we can use the formula:
Percentage decrease = ((Initial stability - Final stability) / Initial stability) x 100
Given: Initial stability = 95Final stability = 80
Substitute the values into the formula: Percentage decrease = ((95 - 80) / 95) x 100 Percentage decrease
= (15 / 95) x 100 Percentage decrease = 0.1579 x 100 Percentage decrease = 15.79
Therefore, the impact of unauthorized changes on system stability in terms of percentage decrease is
15.79
3. Question: In an IT change management audit, it was found that out of 100 changes implemented, 10
were unauthorized. Calculate the percentage of unauthorized changes in the IT change management process.
Solution: To calculate the percentage of unauthorized changes, divide the number of unauthorized
changes by the total number of changes and then multiply by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes) *
100
Percentage of unauthorized changes = (10 / 100) * 100 Percentage of unauthorized changes = 0.1 * 100
Percentage of unauthorized changes = 10
Therefore, the percentage of unauthorized changes in the IT change management process is 10
4. Question: During an audit of IT change management processes, 15 unauthorized changes were
identified in a system. If the total number of changes made to the system was 100, determine the percentage
of unauthorized changes.
Solution: To find the percentage of unauthorized changes, we first need to calculate the total percentage
of unauthorized changes out of the total changes made.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes) *
100 Percentage of unauthorized changes = (15 / 100) * 100 Percentage of unauthorized changes = 15
Therefore, the percentage of unauthorized changes during the audit of IT change management processes
was 15
5. Question: During an audit of an organization’s IT change management processes, a total of 60
change requests were randomly selected for review. Out of these, 40 were found to have complete docu-
mentation and proper record-keeping practices. Calculate the percentage compliance rate for documentation
and record-keeping practices in IT change management processes.
Solution: To find the compliance rate in percentage, use the formula:
Compliance Rate (
Given: Number of compliant change requests = 40 Total number of change requests = 60
Plugging in the values: Compliance Rate (Compliance Rate (Compliance Rate (
Therefore, the compliance rate for documentation and record-keeping practices in IT change manage-
ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT Change Management Audit was 15
11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?
Solution: To calculate the percentage of unauthorized changes detected during the audit, we need to di-
vide the number of unauthorized changes by the total number of change requests reviewed and then multiply
by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100 Percentage of unauthorized changes = (20 / 100) * 100 Percentage of unauthorized changes =
20
Therefore, the percentage of unauthorized changes detected during the audit was 20
15. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, 20 were implemented without proper authorization. Calculate the percentage of unau-
thorized changes.
Solution:
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100
Percentage of unauthorized changes = (20 / 100) * 100
Percentage of unauthorized changes = 20
Therefore, the percentage of unauthorized changes in the audit of IT change management processes is
20
16. Question: During an audit of IT change management processes, it was found that out of 100 ran-
domly selected system changes, 20 were unauthorized. What is the percentage of unauthorized system
modifications detected in this sample?
Solution: To calculate the percentage of unauthorized system modifications in the sample, we first need
to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20
17. Question: During an audit of IT change management processes, it was found that 85 out of 100
change requests were properly approved and authorized. Calculate the percentage of approved and autho-
rized changes.
Solution: To find the percentage of approved and authorized changes, we use the formula:
Percentage = (Approved Changes / Total Changes) * 100
Given that Approved Changes = 85 and Total Changes = 100, plug these values into the formula:
Percentage = (85 / 100) * 100 Percentage = 0.85 * 100 Percentage = 85
Therefore, the percentage of approved and authorized changes is 85
18. Question: In a recent audit of an organization’s change management processes, it was found that out
of 100 change requests reviewed, only 85
Solution: To find the compliance rate, we need to calculate the percentage of change requests that had
proper documentation and approvals.
Percentage Compliance Rate = (Number of change requests with proper documentation and approvals /
Total number of change requests) x 100 Percentage Compliance Rate = (85 / 100) x 100 Percentage Com-
pliance Rate = 0.85 x 100 Percentage Compliance Rate = 85
Therefore, the compliance rate for proper documentation and approvals for change requests in the orga-
nization is 85
19. Question: In a particular month, a company’s IT Change Management team processed 50 change
requests. Out of these, 40 were approved, 5 were rejected, and 5 were pending. What is the approval rate of
the change requests processed during that month?
Solution: Total number of change requests processed = Approved + Rejected + Pending Total number
of change requests processed = 40 + 5 + 5 = 50
Approval rate = (Number of Approved changes / Total number of changes) x 100Approval rate = (40 /
50) x 100Approval rate = 0.8 x 100Approval rate = 80
Therefore, the approval rate of the change requests processed during that month is 80
20. Question: During an audit of IT change management processes, a total of 25 unauthorized changes
were discovered out of a sample size of 150 changes reviewed. Calculate the percentage of unauthorized
changes found during the audit.
Solution: To calculate the percentage of unauthorized changes found during the audit, we first need to
determine the ratio of unauthorized changes to the total changes reviewed.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes
reviewed) * 100
Given that the number of unauthorized changes found during the audit is 25 and the total number of
changes reviewed is 150, we can substitute these values into the formula:
Percentage of unauthorized changes = (25 / 150) * 100 Percentage of unauthorized changes = 0.1667 *
100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85
and record-keeping practices in IT change management processes.
Solution: To find the compliance rate in percentage, use the formula:
Compliance Rate (
Given: Number of compliant change requests = 40 Total number of change requests = 60
Plugging in the values: Compliance Rate (Compliance Rate (Compliance Rate (
Therefore, the compliance rate for documentation and record-keeping practices in IT change manage-
ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT Change Management Audit was 15
11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?

100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85
and record-keeping practices in IT change management processes.
Solution: To find the compliance rate in percentage, use the formula:
Compliance Rate (
Given: Number of compliant change requests = 40 Total number of change requests = 60
Plugging in the values: Compliance Rate (Compliance Rate (Compliance Rate (
Therefore, the compliance rate for documentation and record-keeping practices in IT change manage-
ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT Change Management Audit was 15
11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?
Solution: To calculate the percentage of unauthorized changes detected during the audit, we need to di-
vide the number of unauthorized changes by the total number of change requests reviewed and then multiply
by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100 Percentage of unauthorized changes = (20 / 100) * 100 Percentage of unauthorized changes =
20
Therefore, the percentage of unauthorized changes detected during the audit was 20
15. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, 20 were implemented without proper authorization. Calculate the percentage of unau-
thorized changes.

quests) * 100
Percentage of unauthorized changes = (20 / 100) * 100
Percentage of unauthorized changes = 20
Therefore, the percentage of unauthorized changes in the audit of IT change management processes is
20
16. Question: During an audit of IT change management processes, it was found that out of 100 ran-
domly selected system changes, 20 were unauthorized. What is the percentage of unauthorized system
modifications detected in this sample?
Solution: To calculate the percentage of unauthorized system modifications in the sample, we first need
to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20
17. Question: During an audit of IT change management processes, it was found that 85 out of 100
change requests were properly approved and authorized. Calculate the percentage of approved and autho-
rized changes.

Percentage = (Approved Changes / Total Changes) * 100
Given that Approved Changes = 85 and Total Changes = 100, plug these values into the formula:
Percentage = (85 / 100) * 100 Percentage = 0.85 * 100 Percentage = 85
Therefore, the percentage of approved and authorized changes is 85
18. Question: In a recent audit of an organization’s change management processes, it was found that out
of 100 change requests reviewed, only 85
Solution: To find the compliance rate, we need to calculate the percentage of change requests that had
proper documentation and approvals.
Percentage Compliance Rate = (Number of change requests with proper documentation and approvals /
Total number of change requests) x 100 Percentage Compliance Rate = (85 / 100) x 100 Percentage Com-
pliance Rate = 0.85 x 100 Percentage Compliance Rate = 85
Therefore, the compliance rate for proper documentation and approvals for change requests in the orga-
nization is 85
19. Question: In a particular month, a company’s IT Change Management team processed 50 change
requests. Out of these, 40 were approved, 5 were rejected, and 5 were pending. What is the approval rate of
the change requests processed during that month?
Solution: Total number of change requests processed = Approved + Rejected + Pending Total number
of change requests processed = 40 + 5 + 5 = 50
Approval rate = (Number of Approved changes / Total number of changes) x 100Approval rate = (40 /
50) x 100Approval rate = 0.8 x 100Approval rate = 80
Therefore, the approval rate of the change requests processed during that month is 80
20. Question: During an audit of IT change management processes, a total of 25 unauthorized changes
were discovered out of a sample size of 150 changes reviewed. Calculate the percentage of unauthorized
changes found during the audit.
Solution: To calculate the percentage of unauthorized changes found during the audit, we first need to
determine the ratio of unauthorized changes to the total changes reviewed.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes
reviewed) * 100
Given that the number of unauthorized changes found during the audit is 25 and the total number of
changes reviewed is 150, we can substitute these values into the formula:
Percentage of unauthorized changes = (25 / 150) * 100 Percentage of unauthorized changes = 0.1667 *
100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?

approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?

approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT Change Management Audit was 15
11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?
Solution: To calculate the percentage of unauthorized changes detected during the audit, we need to di-
vide the number of unauthorized changes by the total number of change requests reviewed and then multiply
by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100 Percentage of unauthorized changes = (20 / 100) * 100 Percentage of unauthorized changes =
20
Therefore, the percentage of unauthorized changes detected during the audit was 20
15. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, 20 were implemented without proper authorization. Calculate the percentage of unau-
thorized changes.

quests) * 100
Percentage of unauthorized changes = (20 / 100) * 100
Percentage of unauthorized changes = 20
Therefore, the percentage of unauthorized changes in the audit of IT change management processes is
20
16. Question: During an audit of IT change management processes, it was found that out of 100 ran-
domly selected system changes, 20 were unauthorized. What is the percentage of unauthorized system
modifications detected in this sample?
Solution: To calculate the percentage of unauthorized system modifications in the sample, we first need
to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20
17. Question: During an audit of IT change management processes, it was found that 85 out of 100
change requests were properly approved and authorized. Calculate the percentage of approved and autho-
rized changes.
Solution: To find the percentage of approved and authorized changes, we use the formula:
Percentage = (Approved Changes / Total Changes) * 100
Given that Approved Changes = 85 and Total Changes = 100, plug these values into the formula:
Percentage = (85 / 100) * 100 Percentage = 0.85 * 100 Percentage = 85
Therefore, the percentage of approved and authorized changes is 85
18. Question: In a recent audit of an organization’s change management processes, it was found that out
of 100 change requests reviewed, only 85
Solution: To find the compliance rate, we need to calculate the percentage of change requests that had
proper documentation and approvals.
Percentage Compliance Rate = (Number of change requests with proper documentation and approvals /
Total number of change requests) x 100 Percentage Compliance Rate = (85 / 100) x 100 Percentage Com-
pliance Rate = 0.85 x 100 Percentage Compliance Rate = 85
Therefore, the compliance rate for proper documentation and approvals for change requests in the orga-
nization is 85
19. Question: In a particular month, a company’s IT Change Management team processed 50 change
requests. Out of these, 40 were approved, 5 were rejected, and 5 were pending. What is the approval rate of
the change requests processed during that month?
Solution: Total number of change requests processed = Approved + Rejected + Pending Total number
of change requests processed = 40 + 5 + 5 = 50
Approval rate = (Number of Approved changes / Total number of changes) x 100Approval rate = (40 /
50) x 100Approval rate = 0.8 x 100Approval rate = 80
Therefore, the approval rate of the change requests processed during that month is 80
20. Question: During an audit of IT change management processes, a total of 25 unauthorized changes
were discovered out of a sample size of 150 changes reviewed. Calculate the percentage of unauthorized
changes found during the audit.
Solution: To calculate the percentage of unauthorized changes found during the audit, we first need to
determine the ratio of unauthorized changes to the total changes reviewed.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes
reviewed) * 100
Given that the number of unauthorized changes found during the audit is 25 and the total number of
changes reviewed is 150, we can substitute these values into the formula:
Percentage of unauthorized changes = (25 / 150) * 100 Percentage of unauthorized changes = 0.1667 *
100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:

approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?

Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT Change Management Audit was 15
11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?
Solution: To calculate the percentage of unauthorized changes detected during the audit, we need to di-
vide the number of unauthorized changes by the total number of change requests reviewed and then multiply
by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100 Percentage of unauthorized changes = (20 / 100) * 100 Percentage of unauthorized changes =
20
Therefore, the percentage of unauthorized changes detected during the audit was 20
15. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, 20 were implemented without proper authorization. Calculate the percentage of unau-
thorized changes.

quests) * 100
Percentage of unauthorized changes = (20 / 100) * 100
Percentage of unauthorized changes = 20
Therefore, the percentage of unauthorized changes in the audit of IT change management processes is
20
16. Question: During an audit of IT change management processes, it was found that out of 100 ran-
domly selected system changes, 20 were unauthorized. What is the percentage of unauthorized system
modifications detected in this sample?
Solution: To calculate the percentage of unauthorized system modifications in the sample, we first need
to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20
17. Question: During an audit of IT change management processes, it was found that 85 out of 100
change requests were properly approved and authorized. Calculate the percentage of approved and autho-
rized changes.
Solution: To find the percentage of approved and authorized changes, we use the formula:
Percentage = (Approved Changes / Total Changes) * 100
Given that Approved Changes = 85 and Total Changes = 100, plug these values into the formula:
Percentage = (85 / 100) * 100 Percentage = 0.85 * 100 Percentage = 85
Therefore, the percentage of approved and authorized changes is 85
18. Question: In a recent audit of an organization’s change management processes, it was found that out
of 100 change requests reviewed, only 85
Solution: To find the compliance rate, we need to calculate the percentage of change requests that had
proper documentation and approvals.
Percentage Compliance Rate = (Number of change requests with proper documentation and approvals /
Total number of change requests) x 100 Percentage Compliance Rate = (85 / 100) x 100 Percentage Com-
pliance Rate = 0.85 x 100 Percentage Compliance Rate = 85
Therefore, the compliance rate for proper documentation and approvals for change requests in the orga-
nization is 85
19. Question: In a particular month, a company’s IT Change Management team processed 50 change
requests. Out of these, 40 were approved, 5 were rejected, and 5 were pending. What is the approval rate of
the change requests processed during that month?
Solution: Total number of change requests processed = Approved + Rejected + Pending Total number
of change requests processed = 40 + 5 + 5 = 50
Approval rate = (Number of Approved changes / Total number of changes) x 100Approval rate = (40 /
50) x 100Approval rate = 0.8 x 100Approval rate = 80
Therefore, the approval rate of the change requests processed during that month is 80
20. Question: During an audit of IT change management processes, a total of 25 unauthorized changes
were discovered out of a sample size of 150 changes reviewed. Calculate the percentage of unauthorized
changes found during the audit.
Solution: To calculate the percentage of unauthorized changes found during the audit, we first need to
determine the ratio of unauthorized changes to the total changes reviewed.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes
reviewed) * 100
Given that the number of unauthorized changes found during the audit is 25 and the total number of
changes reviewed is 150, we can substitute these values into the formula:
Percentage of unauthorized changes = (25 / 150) * 100 Percentage of unauthorized changes = 0.1667 *
100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85

ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the

11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?
Solution: To calculate the percentage of unauthorized changes detected during the audit, we need to di-
vide the number of unauthorized changes by the total number of change requests reviewed and then multiply
by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100 Percentage of unauthorized changes = (20 / 100) * 100 Percentage of unauthorized changes =
20
Therefore, the percentage of unauthorized changes detected during the audit was 20
15. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, 20 were implemented without proper authorization. Calculate the percentage of unau-
thorized changes.
Solution:
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100
Percentage of unauthorized changes = (20 / 100) * 100
Percentage of unauthorized changes = 20
Therefore, the percentage of unauthorized changes in the audit of IT change management processes is
20
16. Question: During an audit of IT change management processes, it was found that out of 100 ran-
domly selected system changes, 20 were unauthorized. What is the percentage of unauthorized system
modifications detected in this sample?
Solution: To calculate the percentage of unauthorized system modifications in the sample, we first need
to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20
17. Question: During an audit of IT change management processes, it was found that 85 out of 100
change requests were properly approved and authorized. Calculate the percentage of approved and autho-
rized changes.
Solution: To find the percentage of approved and authorized changes, we use the formula:
Percentage = (Approved Changes / Total Changes) * 100
Given that Approved Changes = 85 and Total Changes = 100, plug these values into the formula:
Percentage = (85 / 100) * 100 Percentage = 0.85 * 100 Percentage = 85
Therefore, the percentage of approved and authorized changes is 85
18. Question: In a recent audit of an organization’s change management processes, it was found that out
of 100 change requests reviewed, only 85
Solution: To find the compliance rate, we need to calculate the percentage of change requests that had
proper documentation and approvals.
Percentage Compliance Rate = (Number of change requests with proper documentation and approvals /
Total number of change requests) x 100 Percentage Compliance Rate = (85 / 100) x 100 Percentage Com-
pliance Rate = 0.85 x 100 Percentage Compliance Rate = 85
Therefore, the compliance rate for proper documentation and approvals for change requests in the orga-
nization is 85
19. Question: In a particular month, a company’s IT Change Management team processed 50 change
requests. Out of these, 40 were approved, 5 were rejected, and 5 were pending. What is the approval rate of
the change requests processed during that month?
Solution: Total number of change requests processed = Approved + Rejected + Pending Total number
of change requests processed = 40 + 5 + 5 = 50
Approval rate = (Number of Approved changes / Total number of changes) x 100Approval rate = (40 /
50) x 100Approval rate = 0.8 x 100Approval rate = 80
Therefore, the approval rate of the change requests processed during that month is 80
20. Question: During an audit of IT change management processes, a total of 25 unauthorized changes
were discovered out of a sample size of 150 changes reviewed. Calculate the percentage of unauthorized
changes found during the audit.
Solution: To calculate the percentage of unauthorized changes found during the audit, we first need to
determine the ratio of unauthorized changes to the total changes reviewed.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes
reviewed) * 100
Given that the number of unauthorized changes found during the audit is 25 and the total number of
changes reviewed is 150, we can substitute these values into the formula:
Percentage of unauthorized changes = (25 / 150) * 100 Percentage of unauthorized changes = 0.1667 *
100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85
and record-keeping practices in IT change management processes.

Therefore, the compliance rate for documentation and record-keeping practices in IT change manage-
ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80

change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during

(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?
Solution: To calculate the percentage of unauthorized changes detected during the audit, we need to di-
vide the number of unauthorized changes by the total number of change requests reviewed and then multiply
by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100 Percentage of unauthorized changes = (20 / 100) * 100 Percentage of unauthorized changes =
20
Therefore, the percentage of unauthorized changes detected during the audit was 20
15. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, 20 were implemented without proper authorization. Calculate the percentage of unau-
thorized changes.
Solution:
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100
Percentage of unauthorized changes = (20 / 100) * 100
Percentage of unauthorized changes = 20
Therefore, the percentage of unauthorized changes in the audit of IT change management processes is
20
16. Question: During an audit of IT change management processes, it was found that out of 100 ran-
domly selected system changes, 20 were unauthorized. What is the percentage of unauthorized system
modifications detected in this sample?
Solution: To calculate the percentage of unauthorized system modifications in the sample, we first need
to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20
17. Question: During an audit of IT change management processes, it was found that 85 out of 100
change requests were properly approved and authorized. Calculate the percentage of approved and autho-
rized changes.
Solution: To find the percentage of approved and authorized changes, we use the formula:
Percentage = (Approved Changes / Total Changes) * 100
Given that Approved Changes = 85 and Total Changes = 100, plug these values into the formula:
Percentage = (85 / 100) * 100 Percentage = 0.85 * 100 Percentage = 85
Therefore, the percentage of approved and authorized changes is 85
18. Question: In a recent audit of an organization’s change management processes, it was found that out
of 100 change requests reviewed, only 85
Solution: To find the compliance rate, we need to calculate the percentage of change requests that had
proper documentation and approvals.
Percentage Compliance Rate = (Number of change requests with proper documentation and approvals /
Total number of change requests) x 100 Percentage Compliance Rate = (85 / 100) x 100 Percentage Com-
pliance Rate = 0.85 x 100 Percentage Compliance Rate = 85
Therefore, the compliance rate for proper documentation and approvals for change requests in the orga-
nization is 85
19. Question: In a particular month, a company’s IT Change Management team processed 50 change
requests. Out of these, 40 were approved, 5 were rejected, and 5 were pending. What is the approval rate of
the change requests processed during that month?
Solution: Total number of change requests processed = Approved + Rejected + Pending Total number
of change requests processed = 40 + 5 + 5 = 50
Approval rate = (Number of Approved changes / Total number of changes) x 100Approval rate = (40 /
50) x 100Approval rate = 0.8 x 100Approval rate = 80
Therefore, the approval rate of the change requests processed during that month is 80
20. Question: During an audit of IT change management processes, a total of 25 unauthorized changes
were discovered out of a sample size of 150 changes reviewed. Calculate the percentage of unauthorized
changes found during the audit.
Solution: To calculate the percentage of unauthorized changes found during the audit, we first need to
determine the ratio of unauthorized changes to the total changes reviewed.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes
reviewed) * 100
Given that the number of unauthorized changes found during the audit is 25 and the total number of
changes reviewed is 150, we can substitute these values into the formula:
Percentage of unauthorized changes = (25 / 150) * 100 Percentage of unauthorized changes = 0.1667 *
100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85
and record-keeping practices in IT change management processes.
Solution: To find the compliance rate in percentage, use the formula:

Plugging in the values: Compliance Rate (Compliance Rate (Compliance Rate (
Therefore, the compliance rate for documentation and record-keeping practices in IT change manage-
ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15

11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during

16. Question: During an audit of IT change management processes, it was found that out of 100 ran-
domly selected system changes, 20 were unauthorized. What is the percentage of unauthorized system
modifications detected in this sample?
Solution: To calculate the percentage of unauthorized system modifications in the sample, we first need
to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20
17. Question: During an audit of IT change management processes, it was found that 85 out of 100
change requests were properly approved and authorized. Calculate the percentage of approved and autho-
rized changes.
Solution: To find the percentage of approved and authorized changes, we use the formula:
Percentage = (Approved Changes / Total Changes) * 100
Given that Approved Changes = 85 and Total Changes = 100, plug these values into the formula:
Percentage = (85 / 100) * 100 Percentage = 0.85 * 100 Percentage = 85
Therefore, the percentage of approved and authorized changes is 85
18. Question: In a recent audit of an organization’s change management processes, it was found that out
of 100 change requests reviewed, only 85
Solution: To find the compliance rate, we need to calculate the percentage of change requests that had
proper documentation and approvals.
Percentage Compliance Rate = (Number of change requests with proper documentation and approvals /
Total number of change requests) x 100 Percentage Compliance Rate = (85 / 100) x 100 Percentage Com-
pliance Rate = 0.85 x 100 Percentage Compliance Rate = 85
Therefore, the compliance rate for proper documentation and approvals for change requests in the orga-
nization is 85
19. Question: In a particular month, a company’s IT Change Management team processed 50 change
requests. Out of these, 40 were approved, 5 were rejected, and 5 were pending. What is the approval rate of
the change requests processed during that month?
Solution: Total number of change requests processed = Approved + Rejected + Pending Total number
of change requests processed = 40 + 5 + 5 = 50
Approval rate = (Number of Approved changes / Total number of changes) x 100Approval rate = (40 /
50) x 100Approval rate = 0.8 x 100Approval rate = 80
Therefore, the approval rate of the change requests processed during that month is 80
20. Question: During an audit of IT change management processes, a total of 25 unauthorized changes
were discovered out of a sample size of 150 changes reviewed. Calculate the percentage of unauthorized
changes found during the audit.
Solution: To calculate the percentage of unauthorized changes found during the audit, we first need to
determine the ratio of unauthorized changes to the total changes reviewed.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes
reviewed) * 100
Given that the number of unauthorized changes found during the audit is 25 and the total number of
changes reviewed is 150, we can substitute these values into the formula:
Percentage of unauthorized changes = (25 / 150) * 100 Percentage of unauthorized changes = 0.1667 *
100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85
and record-keeping practices in IT change management processes.
Solution: To find the compliance rate in percentage, use the formula:
Compliance Rate (
Given: Number of compliant change requests = 40 Total number of change requests = 60
Plugging in the values: Compliance Rate (Compliance Rate (Compliance Rate (
Therefore, the compliance rate for documentation and record-keeping practices in IT change manage-
ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT Change Management Audit was 15
11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.

Total number of change requests) x 100 Percentage Compliance Rate = (85 / 100) x 100 Percentage Com-
pliance Rate = 0.85 x 100 Percentage Compliance Rate = 85
Therefore, the compliance rate for proper documentation and approvals for change requests in the orga-
nization is 85
19. Question: In a particular month, a company’s IT Change Management team processed 50 change
requests. Out of these, 40 were approved, 5 were rejected, and 5 were pending. What is the approval rate of
the change requests processed during that month?
Solution: Total number of change requests processed = Approved + Rejected + Pending Total number
of change requests processed = 40 + 5 + 5 = 50
Approval rate = (Number of Approved changes / Total number of changes) x 100Approval rate = (40 /
50) x 100Approval rate = 0.8 x 100Approval rate = 80
Therefore, the approval rate of the change requests processed during that month is 80
20. Question: During an audit of IT change management processes, a total of 25 unauthorized changes
were discovered out of a sample size of 150 changes reviewed. Calculate the percentage of unauthorized
changes found during the audit.
Solution: To calculate the percentage of unauthorized changes found during the audit, we first need to
determine the ratio of unauthorized changes to the total changes reviewed.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes
reviewed) * 100
Given that the number of unauthorized changes found during the audit is 25 and the total number of
changes reviewed is 150, we can substitute these values into the formula:
Percentage of unauthorized changes = (25 / 150) * 100 Percentage of unauthorized changes = 0.1667 *
100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85
and record-keeping practices in IT change management processes.
Solution: To find the compliance rate in percentage, use the formula:
Compliance Rate (
Given: Number of compliant change requests = 40 Total number of change requests = 60
Plugging in the values: Compliance Rate (Compliance Rate (Compliance Rate (
Therefore, the compliance rate for documentation and record-keeping practices in IT change manage-
ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT Change Management Audit was 15
11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?
Solution: To calculate the percentage of unauthorized changes detected during the audit, we need to di-
vide the number of unauthorized changes by the total number of change requests reviewed and then multiply
by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100 Percentage of unauthorized changes = (20 / 100) * 100 Percentage of unauthorized changes =
20
Therefore, the percentage of unauthorized changes detected during the audit was 20

to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20

Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85
and record-keeping practices in IT change management processes.
Solution: To find the compliance rate in percentage, use the formula:
Compliance Rate (
Given: Number of compliant change requests = 40 Total number of change requests = 60
Plugging in the values: Compliance Rate (Compliance Rate (Compliance Rate (
Therefore, the compliance rate for documentation and record-keeping practices in IT change manage-
ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT Change Management Audit was 15
11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?
Solution: To calculate the percentage of unauthorized changes detected during the audit, we need to di-
vide the number of unauthorized changes by the total number of change requests reviewed and then multiply
by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100 Percentage of unauthorized changes = (20 / 100) * 100 Percentage of unauthorized changes =
20
Therefore, the percentage of unauthorized changes detected during the audit was 20
15. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, 20 were implemented without proper authorization. Calculate the percentage of unau-

quests) * 100
Percentage of unauthorized changes = (20 / 100) * 100
Percentage of unauthorized changes = 20
Therefore, the percentage of unauthorized changes in the audit of IT change management processes is
20
16. Question: During an audit of IT change management processes, it was found that out of 100 ran-
domly selected system changes, 20 were unauthorized. What is the percentage of unauthorized system
modifications detected in this sample?
Solution: To calculate the percentage of unauthorized system modifications in the sample, we first need
to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20

23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85
and record-keeping practices in IT change management processes.
Solution: To find the compliance rate in percentage, use the formula:
Compliance Rate (
Given: Number of compliant change requests = 40 Total number of change requests = 60
Plugging in the values: Compliance Rate (Compliance Rate (Compliance Rate (
Therefore, the compliance rate for documentation and record-keeping practices in IT change manage-
ment processes is 66.67
6. Question: In a certain IT organization, the change approval process requires at least 3 levels of
approval before a change can be implemented. If on average each level takes 2 days to review and approve
a change, how many total days, on average, does it take for a change to receive all 3 necessary approvals?
Solution: To find the total number of days required for a change to receive all 3 necessary approvals, we
simply add up the average time it takes for each level to review and approve the change.
Number of levels of approval = 3 Average time for each level to approve a change = 2 days
Total days for all levels to approve the change = Number of levels of approval * Average time per level
Total days = 3 levels * 2 days = 6 days
Therefore, on average, it takes 6 days for a change to receive all 3 necessary approvals in this IT organi-
zation.
7. Question: In an audit assessing the efficacy of IT change management controls, if 95 out of 100
changes made to a system were found to be authorized and controlled, what is the effectiveness percentage
of the change management processes in preventing unauthorized or unplanned changes?
Solution: To find the effectiveness percentage of the change management processes, we first need to
determine the percentage of authorized and controlled changes out of the total changes made.
Authorized and controlled changes = 95 Total changes made = 100
Percentage of authorized and controlled changes = (Authorized and controlled changes / Total changes
made) * 100 = (95 / 100) * 100 = 95
Therefore, the effectiveness percentage of the change management processes in preventing unauthorized
or unplanned changes is 95
8. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, only 80 had documented approvals from the appropriate stakeholders. Calculate the
percentage of change requests with documented approvals.
Solution: To calculate the percentage of change requests with documented approvals, we use the for-
mula:
Percentage =Number of Change Requests with Documented Approvals
Total Number of Change Requests ×100
Given that 80 out of 100 change requests had documented approvals:
Percentage =80
100 ×100 = 0.8×100 = 80%
Therefore, the percentage of change requests with documented approvals is 80
9. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to the system, only 75 had proper documentation and record-keeping. What is the percentage
compliance rate for documentation and record-keeping in IT Change Management Processes?
Solution: To find the compliance rate, we first need to calculate the percentage of changes with proper
documentation and record-keeping out of the total number of changes made.
Compliance rate = (Number of changes with proper documentation / Total number of changes) x 100
Compliance rate = (75 / 100) x 100 Compliance rate = 0.75 x 100 Compliance rate = 75
Therefore, the compliance rate for documentation and record-keeping in IT Change Management Pro-
cesses is 75
10. Question: In an IT Change Management Audit, it was found that there were 15 unauthorized changes
made to the system in a month. If the total number of changes made during that month was 100, calculate
the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we first need to find the proportion of
unauthorized changes to the total number of changes made.
Unauthorized Changes = 15 Total Changes = 100
Percentage of Unauthorized Changes = (Unauthorized Changes / Total Changes) * 100 Percentage of
Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15 * 100 Percentage of
Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT Change Management Audit was 15
11. Question: In a recent audit of IT Change Management Processes, the average time taken to approve
change requests was found to be 3.5 days. If the standard deviation of the approval times is 1.2 days, what
percentage of change requests were approved within 2 days?
Solution: To find the percentage of change requests approved within 2 days, we will use z-score formula:
z=(X-)/
Where: X = 2 days (desired approval time) = 3.5 days (mean approval time) = 1.2 days (standard
deviation)
Substitute the values into the formula:
z = (2 - 3.5) / 1.2 z = -1.25
Now, we will use a standard normal distribution table or calculator to find the percentage corresponding
to z = -1.25. From the table or calculator, we find that the percentage is approximately 10.56
Therefore, about 10.56
12. Question: During an audit of IT change management processes, it was found that there were 15
unauthorized changes made to the system in the past month. If the total number of changes made during
that time was 100, calculate the percentage of unauthorized changes.
Solution: To calculate the percentage of unauthorized changes, we need to divide the number of unau-
thorized changes by the total number of changes and then multiply by 100 to get the percentage.
Percentage of Unauthorized Changes = (Number of Unauthorized Changes / Total Number of Changes)
* 100 Percentage of Unauthorized Changes = (15 / 100) * 100 Percentage of Unauthorized Changes = 0.15
* 100 Percentage of Unauthorized Changes = 15
Therefore, the percentage of unauthorized changes in the IT change management processes audit is 15
13. Question: How many system changes were scrutinized and approved by the Change Control Board
(CCB) during the audit period?
Solution: To assess the effectiveness of the Change Control Board (CCB) in scrutinizing and approving
system changes, we need to know the total number of changes reviewed by the CCB during the audit period.
This number is crucial in determining if all changes are appropriately evaluated and authorized. By keeping
track of the total changes submitted and the changes approved by the CCB, organizations can calculate the
approval rate and identify any potential gaps in the change management process. The numerical answer to
this question will vary based on the specific audit period and organization being assessed.
14. Question: During an audit of an organization’s IT change management processes, it was found that
out of 100 change requests reviewed, 20 were implemented without proper approval or authorization. What
is the percentage of unauthorized changes detected during the audit?
Solution: To calculate the percentage of unauthorized changes detected during the audit, we need to di-
vide the number of unauthorized changes by the total number of change requests reviewed and then multiply
by 100.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100 Percentage of unauthorized changes = (20 / 100) * 100 Percentage of unauthorized changes =
20
Therefore, the percentage of unauthorized changes detected during the audit was 20
15. Question: During an audit of IT change management processes, it was found that out of 100 change
requests reviewed, 20 were implemented without proper authorization. Calculate the percentage of unau-
thorized changes.
Solution:
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of change re-
quests) * 100
Percentage of unauthorized changes = (20 / 100) * 100
Percentage of unauthorized changes = 20
Therefore, the percentage of unauthorized changes in the audit of IT change management processes is
20
16. Question: During an audit of IT change management processes, it was found that out of 100 ran-
domly selected system changes, 20 were unauthorized. What is the percentage of unauthorized system
modifications detected in this sample?
Solution: To calculate the percentage of unauthorized system modifications in the sample, we first need
to find the ratio of unauthorized changes to the total changes and then convert it to a percentage.
Percentage of unauthorized system modifications = (Number of unauthorized changes / Total number of
changes) x 100
In this case, Number of unauthorized changes = 20 Total number of changes = 100
Therefore, Percentage of unauthorized system modifications = (20 / 100) x 100 Percentage of unautho-
rized system modifications = 0.20 x 100 Percentage of unauthorized system modifications = 20
So, the percentage of unauthorized system modifications in the sample is 20
17. Question: During an audit of IT change management processes, it was found that 85 out of 100
change requests were properly approved and authorized. Calculate the percentage of approved and autho-
rized changes.
Solution: To find the percentage of approved and authorized changes, we use the formula:
Percentage = (Approved Changes / Total Changes) * 100
Given that Approved Changes = 85 and Total Changes = 100, plug these values into the formula:
Percentage = (85 / 100) * 100 Percentage = 0.85 * 100 Percentage = 85
Therefore, the percentage of approved and authorized changes is 85
18. Question: In a recent audit of an organization’s change management processes, it was found that out
of 100 change requests reviewed, only 85
Solution: To find the compliance rate, we need to calculate the percentage of change requests that had
proper documentation and approvals.
Percentage Compliance Rate = (Number of change requests with proper documentation and approvals /
Total number of change requests) x 100 Percentage Compliance Rate = (85 / 100) x 100 Percentage Com-
pliance Rate = 0.85 x 100 Percentage Compliance Rate = 85
Therefore, the compliance rate for proper documentation and approvals for change requests in the orga-
nization is 85
19. Question: In a particular month, a company’s IT Change Management team processed 50 change
requests. Out of these, 40 were approved, 5 were rejected, and 5 were pending. What is the approval rate of
the change requests processed during that month?
Solution: Total number of change requests processed = Approved + Rejected + Pending Total number
of change requests processed = 40 + 5 + 5 = 50
Approval rate = (Number of Approved changes / Total number of changes) x 100Approval rate = (40 /
50) x 100Approval rate = 0.8 x 100Approval rate = 80
Therefore, the approval rate of the change requests processed during that month is 80
20. Question: During an audit of IT change management processes, a total of 25 unauthorized changes
were discovered out of a sample size of 150 changes reviewed. Calculate the percentage of unauthorized
changes found during the audit.
Solution: To calculate the percentage of unauthorized changes found during the audit, we first need to
determine the ratio of unauthorized changes to the total changes reviewed.
Percentage of unauthorized changes = (Number of unauthorized changes / Total number of changes
reviewed) * 100
Given that the number of unauthorized changes found during the audit is 25 and the total number of
changes reviewed is 150, we can substitute these values into the formula:
Percentage of unauthorized changes = (25 / 150) * 100 Percentage of unauthorized changes = 0.1667 *
100
Therefore, the percentage of unauthorized changes found during the audit is 16.67
21. Question: In an IT organization, the Change Advisory Board (CAB) meets bi-weekly to review and
approve change requests. Over the course of 6 months, they have reviewed a total of 120 change requests.
Out of these, 90 were approved, and 30 were rejected. What is the percentage of approved changes during
this period?
Solution:
To find the percentage of approved changes, we first need to calculate the total number of change requests
that were considered:
Total change requests = Approved + Rejected Total change requests = 90 + 30 Total change requests =
120
Now, we can calculate the percentage of approved changes:
Percentage of approved changes = (Approved / Total change requests) * 100 Percentage of approved
changes = (90 / 120) * 100 Percentage of approved changes = 0.75 * 100 Percentage of approved changes =
75
Therefore, the percentage of approved changes during this 6-month period is 75
22. Question: During an audit of IT Change Management Processes, it was found that out of 100 recent
changes made to a system, only 80 changes had adequate stakeholder communication and engagement.
Calculate the percentage of changes that did not meet the criteria for adequate stakeholder communication
and engagement.
Solution: Total changes = 100 Changes with adequate stakeholder communication and engagement =
80
Changes without adequate stakeholder communication and engagement = Total changes - Changes with
adequate communication Changes without adequate communication = 100 - 80 = 20
Percentage of changes without adequate communication = (Changes without adequate communication /
Total changes) * 100Percentage of changes without adequate communication = (20 / 100) * 100
Therefore, 20
23. Question: During an audit of IT change management processes, an organization identified 25 unau-
thorized change requests out of a total of 200 change requests reviewed. What is the percentage of unautho-
rized change requests in the sample?
Solution:
Step 1: Calculate the percentage of unauthorized change requests in the sample. Percentage of unautho-
rized change requests = (Number of unauthorized change requests / Total number of change requests) * 100
Percentage of unauthorized change requests = (25 / 200) * 100 Percentage of unauthorized change requests
= 0.125 * 100 Percentage of unauthorized change requests = 12.5
Therefore, the percentage of unauthorized change requests in the sample is 12.5
24. Question: In an IT Change Management Process Audit, the approval process for change requests
is assessed. If there were 100 change requests reviewed, and 85 of them were approved according to the
defined criteria, what is the approval rate in percentage?
Solution: Approval Rate = (Number of Approved Change Requests / Total Number of Change Requests)
* 100 Approval Rate = (85 / 100) * 100 Approval Rate = 0.85 * 100 Approval Rate = 85
Therefore, the approval rate of change requests in the IT Change Management Process Audit is 85
25. Question: In an IT Change Management Process audit, the Change Control Board (CCB) approved
85 out of 100 proposed changes. What is the approval rate of the CCB in percentage?
Solution: To find the approval rate of the CCB, we need to divide the number of approved changes by
the total number of proposed changes and then multiply by 100 to get the percentage.
Approval rate = (Number of approved changes / Total number of proposed changes) * 100 Approval rate
= (85 / 100) * 100 Approval rate = 0.85 * 100 Approval rate = 85
Therefore, the approval rate of the CCB in percentage is 85
