		Total Normal Cost

1. Calculate the acceleration cost/month for each activity.

2. List all paths and their associated total normal time.

Path example: Start -> .... -> .... -> Finish = ... months.

3. Which path is the critical path? Why?

4. How long will it take to finish this project using the normal time?

5. Calculate the total normal cost.

6. If you want to reduce the project duration by 1 month, which activity will you

accelerate? Why? What is the total normal cost + acceleration cost.

7. After reducing the project duration by 1 month, you still want to reduce the project duration by another 1 month for a total of 2 months. Which activity will you accelerate? Why? What is the total normal cost + cumulative acceleration cost.
