Question

Three critical activities (A, B, and C) have crash costs per hour of $100, $150, and $200, respectively. Which of these activities should be crashed first?

Group of answer choices

a. Cannot be determined from the information given

b. A

c. B

d. C

Answer 1

Activity A should be crashed first in a project schedule because it has the lowest crash cost per hour of $100, compared to B and C which have higher crash costs of $150 and $200 respectively.

Step-by-step explanation:

When deciding which activities to crash in a project schedule, the goal is to determine which activity will have the smallest impact on the overall project cost when the duration of the activity is reduced. The activities A, B, and C have crash costs per hour of $100, $150, and $200, respectively. To minimize the additional cost, we should start with the activity that has the lowest crash cost per hour.

Given the options, activity A should be crashed first as it has the lowest crash cost of $100 per hour. Crashing activity A before activities B and C will result in less additional cost to the project when the goal is to shorten the project duration. Thus, the correct answer is choice b: Activity A.
