3. Accelerate the project by 2 days; you may have to do so 1 day at a time.
Record the total cost. When compressing an activity, reflect the increase in
its direct cost as an extra cost (acceleration cost) in its budget in the schedul-
ingprogram.YoumayhavetocreateanExcelspreadsheettocalculatethe
total cost.
4. Accelerate the project by an additional 2 days. Record the total cost.
5. Accelerate the project 1 extra day at a time. Determine the least cost and
least-cost duration. Print a tabular report and a bar chart displaying all activities,
along with their durations, organized by Responsibility.
6. Keep accelerating the project until it is completely crashed. Determine the crash
duration and the associated crash cost.
7. On a separate page, record the following:
a. Normal duration (number of days and date) and normal cost
b. Least-cost duration and least cost
c. Crash duration and crash cost
