Q16 · Level 5 · CM-PMG-0003
A PERT-CPM hybrid project has the following data for activity X:
- Optimistic = 6, Most likely = 9, Pessimistic = 18 days
- ES = 10, LS = 16
- Activity X feeds into activity Y (ES_Y = 19) and activity Z (ES_Z = 22).
Calculate: (a) PERT expected time, (b) Total float, (c) Free float, (d) If the project deadline requires TF ≤ 3 days for all activities, should activity X be expedited, and by how much?
Q17 · Level 5 · CM-PMG-0008
A PERT network has two possible critical paths:
Path 1: Expected duration = 40 days, Variance = 25 days²
Path 2: Expected duration = 38 days, Variance = 49 days²
The project deadline is 45 days. Which path is more likely to cause a delay, and what is the probability of completing the project within the deadline considering both paths?
