Just wanting to make sure I completed the homework assignment correctly. Thank you.
BA 476 Project Management
Week 9 Assignment – Crashing a Project
Complete the worksheets below to calculate the total costs for each duration of the project. In each worksheet:
Fill in the values in all boxes, including the letter x where appropriate
Respond everywhere you see an underscore (the cost questions and the question at the end)
Highlight the box(es) for the activities that you crashed
Add emphasis to arrows to show the critical path(s) (see example and note in the first worksheet below).
Activity | Crash cost (slope) | Max crash time | Normal time | Normal cost | ||
20 | 60 | |||||
40 | 40 | |||||
30 | ||||||
10 | 10 | |||||
90 | 100 | |||||
50 | 20 | |||||
40 | 60 | |||||
30 | 40 | |||||
100 | 110 | |||||
Total: | 470 |
Project duration: 17 time units (indirect costs, $2000)
With the exception of the costs, I’ve completed this first worksheet for you. This worksheet shows the normal times, so I did not highlight any of the boxes.

To add emphasis to the arrows on the critical path (as shown in the worksheet above):
Click on the arrow to select it (or use Ctrl+Click to select multiple arrows)
Click the Format tab on the ribbon
Click the Shape Outline dropdown arrow
Point to Weight, and click the 3 pt option
Repeat for all arrows on the critical path(s).
Steps might vary slightly in different versions of Microsoft Word.

No need to crash beyond this point. Just respond to the following question:
What is the optimum cost-time point for the project (i.e. the duration that produces the lowest overall cost)? Provide the number of time units and the total project costs for that time unit. _______________
12 Units / 1250+740=1990
