Welcome

Welcome!
Please read this page (in particular) very carefully.
Instructions
You need to understand how to send your assignments (deliverables)
to your instructor. The tabs (bottom of each sheet) in this
document contain all of the deliverables expected of you.
If you need help along the way, look for these special cells that have a red indicator
in the corner. It looks like the "Read me" box to the right: Read me
Simply slide your cursor over the red-cornered cell and you will get more information.
The format for all of the deliverables is the same:
The 'objective' is in black font. It describes what you are doing the particular deliverable.
The next segment is in green font. These are your instructions.
The blue font is the data (where applicable) that you will need to complete the deliverable.
Software
We are using Excel software for the projects. You may use other software
to complete your projects, but please 'report' your answers in the Excel format
described below.
You may complete your assignments with any version of Excel software.
All assignments can easily be completed with a basic copy of Excel.
There is also an Add-In feature which is available for Excel that can be helpful,
although it is not required. The Add-In feature comes free with each Excel package,
although it may not be currently loaded into your copy of Excel.
Following are the simple instruction for loading the Excel Add-ins for both Excel 2003
and Excel 2007. (Slide your cursor over the red-cornered cells to read)

The project

FINANCE PROJECT
Deposit Delays Affecting Customers at Quick-Turn-Around Bank
Project Background:
Jeff Anderson, the President of Quick-Turn-Around Bank (QTAB), has been reading
about the growing impact of Lean Six Sigma in the financial services sector.
Ted Maze is the Quality Manager.
He has been reading about successful Lean Six Sigma projects in banking including:
- projects to reduce account attrition
- projects to optimize account retention
- projects to decrease check deposit errors
- projects to improve check deposit processing time
- projects to enhance electronic statement delivery
- projects to eliminate unnecessary paper reports
- projects to enhance the transition from prospect to client enrollment
- projects to reduce check defects
- projects to reduce loan approval cycle time
- projects to reduce personal overdraft write-offs
Jeff sees opportunities for his bank in each of the above projects, but Ted wants
to begin with a project that will have high impact in improving customer satisfaction.
Jeff has looked at recent customer data and of the 374,400 customers, 2,047
filed customer complaints relating to the time delays in the availability of
deposited funds following a customer banking deposit. One customer deposited
a check from their stock broker’s interest bearing checking account for $8,658
with QTAB and the amount was not available in the customer's account
for 7 days. Jeff has hired a Black Belt to lead a project to address the following
question:
What do deposit delays mean to the bank and to customer satisfaction?
Please 'hand-in' your assignments throughout the course. DO NOT SAVE THEM FOR THE END.
Procrastinators: The deadline for completing all project deliverables is 7 days prior to the end of the course.

Define (Project Charter)

Objective:
A problem statement needs to be developed.
There needs to be a business case so that management will
buy-in to having the team working on the project. The scope of
the project also needs to be decided upon. This is important to ensure
a successful completion. If the scope is too broad, a success
may not be realized for years, or may not happen at all.
Instructions for you:
Create a project charter based "Create a charter?"
upon the information in the introduction. (see "The project" tab)
In reality, you would fill in a charter with team members' names,
stake holders, etc. We are not interested in those details for this
simulation, but we do want to see what you come up with for four (4)
items: Problem statement, business case, goal and project scope.
Be sure to review the week 2 virtual class for more information on Project Charters before you submit this assignment!

Instructor: Acting as your real-world sponsor, I would need to be sold on why we need to do this project. I wouldn't have time to read long explanations. I would need to know what this project is all about and how it impacts the strategic objectives of the organization. I would need a short, to-the-point compelling reason why we need to do this.
Instructor: In the problem statement, we 'sell' the need for the project with specific and measureable data. One or two sentence description of the symptoms arising from the problem to be addressed. It will often parallel the Business Case, but will be more specific and focused. Answer; What’s wrong? Where is the problem appearing? How big is the problem? What is the impact of the problem on the business?
Instructor: The Goal Statement and Problem Statements are a matched pair. What is your target improvement for this project, including a target date? George Eckes mentions a 50% improvement as a possible target for Six Sigma projects. Is a 50% improvement enough in this case?
Instructor: Outline the project scope in process terms (where does it start and stop - ie. starts with the point of initial deposit at branch and ends when the funds are accessible in the customers account), and identify any constraints and assumptions. How much of our work time can be devoted to project per week? Do we have any authority to spend money? Who (what) are our internal/external resources? Also be sure to review week #2 archived virtual class session for additional information and helpful hints! What the scope is not: -It is not merely a timeline (i.e., when the Six Sigma project is to begin and when it is expected to end.) -It is not restating the problem being attacked.
Instructor: Additional information about project charters can be found in your Online Textbook. I also HIGHLY recommend reviewing week #2 archived virtual class session for additional information and helpful hints for the assignment!

Analyze (Pareto Chart)

Objective:
You need to determine the 'biggest contributors to the problem.'
One tool to accomplish this is the Pareto Chart
As stated in the problem, you have unhappy customers.
Your team has had to go out and collect customer data. That data
(blue font far below) will be useful in constructing the Pareto Chart.
Instructions
Using the data below, construct a Pareto chart.
We realize that you could simply pick the two or three
process components without actually creating the Pareto Chart, but we want you to
actually create the Pareto Chart because in reality management likes to see simple
charts where they don't have to analyze the data to see the picture. That is why the
Pareto Chart is a powerful business tool.
Notice: The shaded section below has a practice problem intended to help you with this assignment.
If you want to skip this hypothetical problem, you can.
Hypothetical problem (This is NOT the project data which is why this is separated in a shaded box)
Just to show you how this works, let's say the responses were as follows:
Let's say that data reveals the following counts for beach-related injuries for the month of July.
Injury categories # of incidents
Cuts from broken glass 12 This green area is just for practice.
Surf boarding injuries 37 The project is below in blue.
Fishing related injuries 41
Jelly fish stings 45 This is a hypothetical example
Skim boarding accidents 29 You will be doing this using different
Hit with flying toy 79 data for your project, but this is merely
Sprained ankle 43 showing you how to do it.
Jet Ski accidents 34
Burns from grills 52
Misc. 22
The first thing you would have to do is sort the data from the largest count of injuries to the smallest.
It would look like this after sorting.
Then, you would create a cumulative percentage column. Click once on any of the
cumulative percentages to see the formula.
Injury categories # of incidents Cumulative %
Hit with flying toy 79 20% How did you get 20?
Burns from grills 52 33% How did you get 33?
Jelly fish stings 45 45%
Sprained ankle 43 56%
Fishing related injuries 41 66%
Surf boarding injuries 37 75%
Jet ski accidents 34 84%
Skim boarding accidents 29 91%
Misc. 22 97%

Instructor: Is it bell-shaped? Remember, you would need an infinite sample size for it to be perfect. Close wins the cigar. We want to know if the distributions are 'approximately' normal or randomly distributed. In other words, do the distributions appear to be an approximate bell curve. For a distribution to be skewed, the tails should appear 'significantly' distorted. More than one peak in the data indicates the data is not normally distributed.

Instructor: Excel 2003 - 2 Options Option #1 (Quick and Dirty draft of a histogram) 1) Click TOOLS in the Excel toolbar 2) Click Data Analysis 3) Select HISTOGRAMS and then click OK 4) The cursor should be blinking in the "Input Range" box 5) Highlight your data 6) Click "New Worksheet Ply" 6) Skip the bin range option, and all other options 7) Check the "Chart Output" box 8) Click OK, and your histogram will appear. 9) You may drag your mouse over the corner of the histogram graph to enlarge it. 10) Do NOT delete the MORE category if there are data values in it. Option #2 (A more polished copy where you determine the bin ranges, rather than Excel) 1) Click TOOLS in the Excel toolbar 2) Click Data Analysis 3) Select HISTOGRAMS and then click OK 4) Determine the range of the data set, from your smallest to your largest data value 5) Add one value (in the unit you are measuring) for 'range with inclusion' (Example: .14 (range) + .01 = .15) 6) Determine the appropriate number of bars for your sample size (Example: < 50 data points use 5, 6 or 7 bars) 7) Calculate both the beginning and ending point of each cell and list the beginning and ending points of each bin in separate cells. For example, if you have a range of .15, you could have 5 cells with .03 data value per cell. 8) Now you have an idiosyncrasy of Excel. Excel will give you the option of designating the bin ranges. But, you should give Excel the ENDING value of each bin rather than the beginning value. Highlight the cells that include the ending value of each bin under the BIN RANGE option. 9) Highlight your complete data set under the INPUT RANGE option 10) Check on CHART OUTPUT and where you want the histogram chart located. (New worksheet or imbedded) 11) Click OK 12) You may drag your mouse over the corner of the histogram chart to enlarge it. 13) When Excel drafts histograms, the bars do not adjoin. Ideally, we want the bars of a histogram to adjoin because we are graphing continuous data. To make the bars adjoin, right click on top of bars and choose FORMAT DATA SERIES. In Excel 2003, you will have to select OPTIONS. Then set the GAP to Zero. 14) To change the color scheme of the histogram, right click somewhere outside of the bars in the graph and choose FORMAT PLOT AREA. You can choose many color formats. 15) When you plan the cell intervals, there are no data points in the MORE category, so you may delete it, because the MORE category is often confusing to people. DO NOT delete the MORE category if it has data points in it. 16) Only go through these more detailed steps if you are interested in a polished Histogram. Otherwise run a quick draft of the histogram with Option #1. If you would like to PRINT these instructions, right click on the cell, and select EDIT COMMAND.

Instructor: Excel 2007 - 2 Options Option #1 (Quick and Dirty draft of a histogram) 1) Click DATA tab 2) Go to ANALYSIS category on the DATA tab 3) Click on DATA ANALYSIS (If you do not see DATA ANALYSIS, refer to the EXCEL EXAMPLES tab at the bottom of this spreadsheet for instructions in loading the DATA ANALYSIS features.) 4) Select HISTOGRAMS and then click OK 5) The cursor should be blinking in the "Input Range" box 6) Highlight your data 7) Click in "New Worksheet Ply" 8) Skip the bin range option, and other options 9) Check the "Chart Output" box 10) Click OK 11) You may drag your mouse over the corner of the graph to enlarge it. Option #2 (A More polished copy where you determine the bin ranges) 1) Click DATA tab 2) Go to ANALYSIS category on the DATA tab 3) Click on DATA ANALYSIS (If you do not see DATA ANALYSIS, refer to the EXCEL EXAMPLES tab at the bottom of this spreadsheet for instructions in loading the DATA ANALYSIS features.) 4) Select HISTOGRAMS and then click OK 5) Determine the range of the data set, from your smallest to your largest data value 6) Add one value (in the unit you are measuring) for 'range with inclusion' (Example: .14 (range) + .01 = .15) 7) Determine the appropriate number of bars for your sample size (Example: < 50 data points use 5, 6 or 7 bars) 8) Calculate both the beginning and ending point of each cell and list the beginning and ending points of each bin in separate cells. For example, if you have a range of .15, you could have 5 cells with .03 data value per cell. 9) Now you have an idiosyncrasy of Excel. Excel will give you the option of designating the bin ranges. But, you should give Excel the ENDING value of each bin rather than the beginning value. Highlight the cells that include the ending value of each bin under the BIN RANGE option. 10) Highlight your complete data set under the INPUT RANGE option 11) Check on CHART OUTPUT and where you want the histogram chart located. (New worksheet or imbedded) 12) Click OK 13) You may drag your mouse over the corner of the histogram chart to enlarge it. 14) When Excel drafts histograms, the bars do not adjoin. Ideally, we want the bars of a histogram to adjoin because we are graphing continuous data. To make the bars adjoin, right click on top of bars and choose FORMAT DATA SERIES.

Analyze (Chi Square)

Objective:
Jeff Anderson, the President of QTAB, wants to know how the home office
bank compares with the other branches' ability to successfully meet the
customers' requirements regarding deposit cycle time. Data was collected
from 5 branches in total, including QTAB. See data below. Jeff wants to
know if the choice of bank affects the likelihood of successfully
meeting the customers' requirements for deposit time. Jeff is willing to take a 5%
chance of being wrong.
Instructions:
We highly recommend working through the practice example in the shaded area below
before tackling this deliverable.
1. State the practical problem.
2. State the null and alternate hypotheses.
3. Compute the chi-square statistic. Excel 2003
4. Determine the chi-square critical value.
5. What conclusions can you draw? Excel 2007
"Hypothesis statement?"
"Write-up my conclusion?"
Data:
Wins indicate that the bank has met the customer requirement for deposits.
Losses indicate that the bank has not met the customer requirements.
Data:
Wins Losses Institution
29 64 Bank 1
20 56 Bank 2
24 33 Bank 3
46 69 Bank 4
11 54 Quick Turn Around
Some help for you using an optional practice example:
It is recommended, but not required to complete this example in the shaded area.
You first need to calculate the expected values. It is best to make
a table as shown in Step 1. For example, males and females watch various
TV stations. Let's say that we want to find out if gender is dependent
or independent of television station preferences.
The practice data follows:
WKBW WBEN WGR Totals
Males 62 54 25 141
Females 44 50 15 109
Totals 106 104 40 250
Step 1. Calculate each of the 'expected values.' We will do
the first two for you.
a. Probability of viewer being male is 141 / 250 = 0.564
(refer to the cells in the table above)
b. Probability of viewer preferring WKBW is 106 / 250 = 0.424
c. Probability of viewer preferring WKBW AND being male
is 0.564 x 0.424 = 0.239136
d. Expected number of viewers in this cell is 0.239136 x 250 = 59.784
etc…
a. Probability of viewer being female is 109 / 250 = 0.436
b. Probability of viewer preferring WKBW is 106 / 250 = 0.424
c. Probability of viewer preferring WKBW AND being
female is 0.436 x 0.424 = 0.184864
d. Expected number of viewers in this cell is 0.184864 x 250 = 46.216
etc…
Repeat this for all six cells. To check your work, the totals
(across and down) should add up very close to the (across and
and down) Totals of the observed values. Here is how your
chart should appear when finished: The 'expected values'
are in [brackets.]
WKBW WBEN WGR Totals
Males 62 [59.784] 54 [58.656] 25 [22.560] 141
Females 44 [46.216] 50 [45.344] 15 [17.440] 109
Totals 106 104 40 250
Step 2. Compare the OBSERVED [EXPECTED]
Example: For the first cell (Males/WKBW), the formula is:
Observed minus [Expected] Squared divided by [Expected] as follows:
(62-59.784)2 divided by 59.784 = 0.082140
For the 2nd value… (54-58.656)2 divided by 58.656 = 0.369584
For the 3rd value… (25-22.560)2 divided by 22.560 = 0.263901
For the 4th value… (44-46.216)2 divided by 46.216 = 0.106254
For the 5th value… (50-45.344)2 divided by 45.344 = 0.478086
For the 6th value… (15-17.440)2 divided by 17.440 = 0.341376
Step 3. Add those chi-square values and you should get 1.64134 (rounded to 1.64)
This is your calculated chi-square test statistic.
Step 4. Determine the significance level. (e.g., .05 or .01 or .1)
This is up to the discretion of the team and the team's choice is based
upon what level of risk they are willing to live with.
Step 5. Determine the Degrees of Freedom (df) for the rows and
the columns. You will need this to find the critical value in
the table in the textbook.
df=(number of rows minus 1) multiplied by
the (number of columns minus 1) So, in this particular
case it would be (2-1 multiplied by 3-1) = 2
Step 6. Go to the chi-square table in the Online textbook and determine
the critical value. Let's assume a 95% confidence level, and we know we have
2 df (from above), using the table we find the respective critical value of 5.99.
We now can compare the calculated test statistic (1.64) to the critical
value (5.99). If the test statistic is greater than the critical value, you can conclude
'reject' the null. If not, then you conclude 'fail to reject' the null hypothesis.

Instructor: For 5% alpha, you should get a value between 8 and 12. Try checking the critical value at 1% alpha…..
Instructor: A quick refresher on hypothesis statements. I recommend starting off with thinking about what you are testing. The null hypothesis is always what we would expect by chance alone. In this example, we would expect the deposit cycle time to be independent of the choice of bank branch. We would expect the branch policies to be consistent, with similar deposit time results. (Our choice of banking branches doesn't matter.) The alternative hypothesis, in contrast, is attempting to test if the deposit time is NOT independent of the branches, or in other words, the choice of branch matters in regard to deposit times. Now you should be able to write your Null and Alternative Hypothesis in standard format. I HIGHLY recommend attending (reviewing) the Chi-Sqr virtual class session for additional information and helpful hints for the assignment. If you would like to print this tip, right click on the cell and select EDIT COMMENT. Then just highlight and copy the text, and paste in a document for printing.
Instructor: To write up your conclusion, you would have either concluded that you: a) failed to reject the NULL at 95% confidence, or b) that you have rejected the NULL at 95% confidence. We do not include a statement that we 'accept the null' in hypothesis testing.
Instructor: You may solve this chi square assignment with Excel, but you will be using two different Excel functions, 'Chitest' and 'Chiinv.' Chitest gives you the p-value when you compare the actual range with the expected range. If your p-value is less than your alpha, you may reject the null. If you want to convert the p-value to your chi square test statistic, use the 'chiinv' to transform the 'probability' statistic to your 'chi square test statistic.' Although you may use Excel in this assignment, you first must still calculate the 'Expected Values" as described in the Sample exercise. Here are the steps..... 1. Now you should have a table with the actual counts, and a separate table with the expected values. 2) If you have an fx in your top Excel bar, click on the fx and type in CHITEST, and OK. If you do not have an fx on the home page, click on INSERT in the top menu and then click on FUNCTION. Next type in CHITEST. 3) Once you have the pop up screen for CHITEST, highlight the data for both the ACTUAL RANGE and the EXPECTED RANGE. Click on OK. 4) The statistical result that you are seeing is the p-value. If your p-value is < your alpha level, you may reject the null. 5) If you would like to convert your p-value to a chi square test statistic, click on fx again and select CHIINV. The CHIINV will convert the p-value to your chi square test statistic. You will then compare this result with your chi square critical value. Since this assignment requires that you report the chi square test statistic, you will be using both the CHITEST function and the CHIINV if you solve the assignment with Excel. If you would like to print this tip, right click on the cell and select EDIT COMMENT. Then just highlight and copy the text, and paste in a document for printing.

Analyze (ANOVA)

Objective:
It was decided to look at different branch operations of the bank to
determine if there was one branch that had better deposit cycle time than the
other branches. The deposit cycle time for making money available to a customer
in Branch 1 appeared to be lower than the other banks.
Use a one way ANOVA to determine if the difference in the deposit cycle time
for Branch 1, as compared to the other Branches, was due to chance fluctuation
or was statistically significant at the 95% confidence level.
Instructions:
1. State the Null and Alternative Hypotheses.
2. Calculate the variance for each of the four branches.
3. Calculate the Total Sum of Squares .
4. Calculate the Branch Sum of Squares.
5. Calculate the Error Sum of Squares.
6. Determine the F-calculated value.
7. Determine the F-critical value from the table in the book.
8. What is your conclusion when comparing the F-calculated with the F-critical value?

Improve (DOE)

Objective:
The bank wants to improve its deposit cycle time. Management feels that some combination of training,
mentoring, and bonus will help them achieve an optimum deposit cycle time. One of your team
members suggests the use of a designed experiment to manipulate three factors (i.e., the amount
of training, the amount of mentoring, and the amount of bonuses). The experiment will manipulate these
factors at different levels (i.e., training at 30 hours vs. 130 hours, mentoring at 87 hours vs. 92 hours, and
varying the amount of the bonuses from $55 to $65). This will be done to see if any of these three factors
individually have an effect on reducing deposit cycle time, or whether there is an interactive effect from
any of these factors that might show an improvement.
Instructions
You will be running an 8 trial full factorial design because interactions are expected.
Low ( - ) High (+)
Training will vary from 30 hours to 130 hours Training 30 130
Mentoring will vary from 87 hours to 92 hours Mentor 87 92
Bonus will be set from $55 to $65 Bonus $55 $65
1. Construct an Main Effects Plot for all three of the factors. We will do the first one for you as
an example: Note: You don't have to use Excel to do this. If you want to do this on a simple piece of paper,
that is fine too. We are not asking for pretty charts if pretty charts don't help you to better
answer the question(s) you are trying to get answered.
Take an average of the results when "training" was set at (30 - low). Then, do the same thing
for when "training" was set at (130 high).

Control (Control Chart)

Objective:
You have learned a lot through the use of the tools and
techniques of Six Sigma. You learned that you had a bi-modal
distribution when you used the histogram. The team determined
the cause of the bi-modal nature and drastically improved the process
right there--and the tool was quite easy to use.
You learned even more with the designed experimentation.
The optimal settings were determined from the results of the DOE.
You thought you were going to learn from the use of the
scatter diagram, but you found out there was no correlation…but, wait
one minute…YOU DID LEARN SOMETHING. You learned there is
no correlation. That is knowledge, isn't it? You also thought you would get
some insight from the use of the mystery tool (aka T test), but you failed
to reject the null. But again, you learned something that you wouldn't
have known otherwise. All good stuff. The team has claimed success.
Other tools were used in this project (aside from the one's you used) and
some design changes were put into place and from all of this, you
have succeeded. Now, you want to be sure that the new process stays that way.
Your team decides to use the XmR chart to ensure the process variation is
behaving predictably. So, in this deliverable, you need to create an XmR primarily
to answer the question, "Is there any assignable-cause variation evident
in the process." You are given total deposit cycle time (in hours) by period.
Instructions
We want to make sure you can calculate control limits. You will need to Control Charts in Excel 2003

Instructor: The formulas for the control limits of the XmR chart are found on pages 681-685 of Book 4 of 4 of your white manuals. Do you understand why we are using a XmR chart in this assignment versus an X-barR chart? ANSWER - We only have individual data points. We do not have rational subgroups.
Instructor: "Yes you do. Next question." (smile)
Instructor: Whether or not a measurement system is discriminate is covered in the lecture in two places. It is covered in the control chart section and it is also covered in the 'Measurement System Evaluation" lecture. First, look at your data. What unit of measurement is being used? You are measuring in hours. For example, if the UCL of your range chart is 42.xx hours and you are measuring fine enough to see 1 hour intervals in the data, then your measurement system is discriminate. It would be possible to have 43 (42+1 for zero) 'possible' units under the UCL of the range chart because you are measuring in one hour intervals. I HIGHLY recommend attending (reviewing) the Control Chart virtual class session for additional information and helpful hints for the assignment!
Instructor: You do not need fancy software to create a control chart. In the "Appendx' there are control chart forms if you prefer not to use Excel.
Instructor: You may calculate r-bar by hand, but here is an alternative for calculating r-bar with Excel. This is a 2-step process. First you need to find the absolute values for the range of each subgroup. Why do we use absolute values? If we only calculated the 'difference' between the cells, we would get both positive and negative numbers. To measure distance, such as range, we only want to work with positive numbers, such as the absolute value. 1. Click on the empty cell directly right of the second value (33) 2. Either click on the fx function in the task bar and select ABS (for absolute value) (If you do not have an fx function in your task bar, select Insert, and select ABS) 3. Click on the first cell (45) 4. Type in a minus sign. 5. Click on the second cell (33). Make sure that the second cell reference is inside of the ( ). 6. Click OK. You should get 12. 7. Now, grab the bottom right-hand corner of the cell you are working with, and drag it all the way down to the bottom of the list of data. This will repeat the formula for you all the way down the list of data. You should have all the range values starting with 12 and ending with the last value of 8. 8. For the 2nd step of this process, you will be taking an average of all of your range values. 9. Click on any empty cell. 10. Click on fx and select AVERAGE or Insert - Function - AVERAGE. 11. Highlight the column of range values that you just created. 12. Click OK and you will have r-bar or the average of your ranges. If you would like to print this tip, right click on the cell and select EDIT COMMENT. Then just highlight and copy the text, and paste in a document for printing.
More help on calculating R-bar using Excel We really intend on you doing this step by hand. R-bar is the average of all of the ranges of subgroup size of 2. For more information about a moving range, you need to revisit the lecture on moving ranges.
Self check: You should get an r-bar between 12 and 15.
Instructor: Please refer to the lecture on how to calculate control limits. This one in particular is for the range.
Self check: You should have gotten a value between 40 and 45.
Instructor: Please refer to the lecture on how to calculate control limits. This one in particular is for the individuals.
Self check: UCL between 75 and 80. LCL between 5 and 10.
Instructor: You should get a value between 12 and 15.
Instructor: You should get a value between 40 and 45.
Instructor: You should get a value between 75 and 80.
Instructor: You should get a value between 9 and 12.
Instructor: We want to see at least 6 'possible' points under the UCL of the range chart. Look at your raw data. What are the closest measurement intervals? 44, 45 or 1 hour intervals You are measuring at 1 hour intervals. We may not have data points at each 1 hour interval, but we are measuring fine enough to detect variation at the 1 hour interval. Based on the UCL of the range chart, would you have more than 6 possible points under the UCL of the range chart? Adequate discrimination just means that we are measuring fine enough to detect variation if it exists. ** Also refer to the helpful hint provided in the Instructions for 4b above!
