Which activity has the highest crash cost in the crashing data?

• A. Activity E
• B. Activity A
• C. Activity B
• D. Activity D

Answer: (A)

In crashing data, the crash cost represents the extra money required to reduce an activity’s duration by one time unit. The activity with the highest crash cost is the most expensive to crash per unit of time saved. Here, Activity E has the largest crash cost value, so shortening its duration costs more per time unit than any other activity. That’s why it’s the least attractive option to crash early in a schedule—crashing it yields less cost-efficient time savings compared with others. In practice, you’d typically crash activities with lower crash costs first to gain the most time per dollar, and only crash Activity E if you’ve exhausted cheaper options or if overall timing demands it.
