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.
- 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.
- Calculate the estimated time for each activity using PERT techniques for the 3 estimates provided. Include a sample calculation.
- Prepare a table that identifies all paths and their lengths. Which path is the critical path?
- During the execution phase of the skit project, one of the activities on the critical path is delayed by one day. Is this serious?
- 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.
Activity | Predecessor | Time (days) |
| | Optimistic | Most Likely | Pessimistic |
1 | None | 2 | 4 | 6 |
2 | None | 5 | 5 | 5 |
3 | 2 | 3 | 5 | 7 |
4 | 1 | 7 | 10 | 13 |
5 | 1 | 11 | 12 | 13 |
6 | 2,4 | 5 | 6 | 7 |
7 | 3 | 9 | 10 | 11 |
8 | 3,6 | 5 | 7 | 9 |
9 | 4 | 7 | 9 | 11 |
10 | 5 | 3 | 3 | 3 |
11 | 7 | 15 | 17 | 19 |
12 | 8 | 6 | 8 | 10 |
13 | 9,10 | 7 | 8 | 15 |
14 | 7 | 12 | 14 | 16 |
15 | 12,13 | 16 | 17 | 18 |
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.
Criteria –
Part 1 | Each response is complete and correct with sufficient detail to demonstrate a thorough understanding of the material. 40points | Responses have minor errors or omissions and may or may not fully demonstrate a thorough understanding of the material. 34points | Responses are incomplete, contain errors and omissions that result in failing to demonstrate understand of the material. 30points | No response or exceptionally poor response submitted for 1 or more questions. 0points |
|
Part 2- AON Diagram | A complete AON diagram includes start and finish nodes and is a correct representation of all paths in the network 15points | The completed AON diagram has some minor errors but includes all paths in the network 12points | The completed AON diagram has major errors that led to incorrect paths or missing paths 10points | No response or the AON diagram is in need of major reconstruction – as submitted it does not demonstrate understanding of diagramming technique. 0points |
|
Part 2 – PERT Estimates | 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 15points | The estimated times for activities has minor errors or omissions that are easily identified; a sample calculation is correct. 12points | 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. 10points | No response or the table of estimated time does not demonstrate an understanding of 3-point estimating technique using PERT analysis. 0points |
|
Part 2 – Paths | A table shows the correct number and lengths of all paths. 15points | One or two paths are missing, or a minor error in calculating path length is observed. 12points | Several errors and omissions; Paths have not been identified; Path lengths have errors; 10points | 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. 0points |
|
Part 2 – Questions 4 and 5 | Responses to questions are complete and correct. 5points | Responses have minor errors or omissions. 4points | Responses don’t demonstrate an understanding of critical path in the application of the July 4th skit 3points | No response. 0points |
|
Mechanics | Solutions are presented in a professional manner with good grammar, correct spelling, and easy to find solutions. 10points | Minor errors in grammar and spelling that are not distracting to the reader. Professional appearance in work submitted. 8.5points | Errors in grammar and spelling are distracting or the presentation of solutions are poor and not easy to follow. 7points | No response. 0points |
