Part 1 Exercise Questions (40 points)

Complete exercise questions 1 (5 pts), 3 (5 pts), 5 (10 pts), 6 (5 pts) and 9 (15 pts) found at the end of Chapter 8.

Part 2 Scheduling Problem (50 points)

Complete the following:

Your child is a member of the school theater group and have been asked to prepare the schedule, etc. for a skit to be performed during the 4th of July celebration in the local village square.  As a volunteer, you offer to serve as the project controller because of your expertise in schedule management.

1. Construct an AON diagram similar to the format used in the Youtube videos found in the commentary using an MS Excel spreadsheet.  Ensure that you include a Start activity and a Finish activity.  Include a legend (example is the one completed in Question 1, Part 1.

2. Calculate the estimated time for each activity using PERT techniques for the 3 estimates provided.  Include a sample calculation.

3. Prepare a table that identifies all paths and their lengths.  Which path is the critical path?

4. During the execution phase of the skit project, one of the activities on the critical path is delayed by one day.  Is this serious?

5. Using the activity estimates for optimistic, pessimistic and most likely time to complete activities on the critical path, qualitatively discuss the estimate uncertainty of the critical path.

You will be assessed on content and mechanics.

Content (90 points): Each element of this assignment has a correct answer.  Your content will be assessed on whether or not you produced a correct diagram, estimate, result, etc. or the degree to how you demonstrate knowledge of scheduling practices in case your diagram, estimate or result are incorrect.

Mechanics (10 points):  The results must include sample calculations (where applicable) and be presented in a professional manner. This is not an academic paper, therefore you do not need to follow APA guidelines. 

 

Your Instructor will use Turn-it-in to ensure your paper is authentic work.  To avoid plagiarism, see the course home page for more information and use the Purdue Online Writing Lab to learn how to paraphrase, summarize and cite the references you use in all academic writing assignments.

Good

Responses have minor errors or omissions and may or may not fully demonstrate a thorough understanding of the material.

30 pts

Poor

Responses are incomplete, contain errors and omissions that result in failing to demonstrate understand of the material.

0 pts

No Response

No response or exceptionally poor response submitted for 1 or more questions.

40 pts

This criterion is linked to a Learning OutcomePart 2- AON Diagram

15 pts

Excellent

A complete AON diagram includes start and finish nodes and is a correct representation of all paths in the network

12 pts

Good

The completed AON diagram has some minor errors but includes all paths in the network

10 pts

Poor

The completed AON diagram has major errors that led to incorrect paths or missing paths

0 pts

No Response

No response or the AON diagram is in need of major reconstruction - as submitted it does not demonstrate understanding of diagramming technique.

15 pts

This criterion is linked to a Learning OutcomePart 2 - PERT Estimates

15 pts

Excellent

A table is used to present results of most likely estimates using PERT technique correctly. A sample calculation is included to verify the student's understanding of 3-point estimating with PERT

12 pts

Good

The estimated times for activities has minor errors or omissions that are easily identified; a sample calculation is correct.

10 pts

Poor

The estimated times are incorrect and have some major errors in the technique used to determine them, or a sample calculation has not been provided.

0 pts

No Response

No response or the table of estimated time does not demonstrate an understanding of 3-point estimating technique using PERT analysis.

15 pts

This criterion is linked to a Learning OutcomePart 2 - Paths

15 pts

Excellent

A table shows the correct number and lengths of all paths.

12 pts

Good

One or two paths are missing, or a minor error in calculating path length is observed

10 pts

Poor

Several errors and omissions; Paths have not been identified; Path lengths have errors;

0 pts

No Response

No response or the table presented has major errors and omissions such that the instructor cannot confirm the student demonstrates an understanding of the material.
