In a PERT network, non-critical activities that have little slack need to be monitored closely:
A) because PERT treats all activities as equally important.
B) because near-critical paths could become critical paths with small delays in these activities.
C) because slack is undesirable and needs to be eliminated.
D) because they are causing the entire project to be delayed.
E) because they have a high risk of not being completed.

Question

Quizplus · Accepted Answer

Non-critical activities with little slack are those that are close to the critical path, meaning that any small delay in them could cause them to become part of the critical path and delay the project overall. Therefore, they need to be monitored closely to avoid such delays. PERT does not treat all activities as equally important, and slack is not necessarily undesirable. Non-critical activities with little slack are not necessarily causing the entire project to be delayed or at high risk of not being completed.
