Question

Consider the following statements regarding project management:Which of the given statements are INCORRECT?

1. PERT is probabilistic and CPM is deterministic.
2. In PERT, network slack on various events is calculated,
3. In PERT, activity duration is normally distributed and project duration is beta distributed.
4. The critical path of a network is the path that takes the shortest time.

• A. All
• B. 3 only
• C. 3, 4
• D. 2, 3

Answer 1

Answer:

C. 3, 4

PERT is probabilistic and CPM is deterministic. PERT calculates network slack while CPM calculates floats. Activity duration in PERT is normally distributed while project duration is beta distributed. The critical path in CPM is the largest path in the network from starting to ending event and defines the minimum time required to complete the project.
