For an activity in a CPM analysis the Early Start time is 15 and the Late Start time is 20. Which of the following statements is true?

a. The duration of this task is zero.
b. The slack for this activity is 20.
c. The activity's late start must happen before its early start.
d. The activity is not on the critical path.
e. The duration of this task is 20.

Sagot :

Answer: D. The activity is not on the critical path.

Explanation:

The critical path refers to the longest path from the start of a project to it's completion and it shows the minimum time that is necessary to complete the entire project.

In this case, the activity is not on the critical path as the early start time and the late start time isn't equal. Also, the difference between the late start time and early start time is 20-15 = 5 and not 0.
