1
What is an accurate difference between the Program Evaluation and Review Technique (PERT) and critical path method (CPM)?
a. Unlike CPM, PERT estimates only when there is no risk of uncertainty.
b. PERT uses different duration estimates whereas CPM uses one specific duration estimate.
c. CPM addresses the risk associated with duration estimates whereas PERT does not.
d. CPM involves more work than PERT because it requires several duration estimates.
