The project team determined that using a multipoint estimate is more appropriate than single point estimate. Which of the following network diagram methods would be MOST appropriate?

Graphical Evaluation and Review Technique (GERT) is used for projects with probabilistic branching and loops, which goes beyond simply using multipoint estimates for activity duration.

Critical Chain Project Management (CCPM) focuses on managing resource dependencies and buffers, not directly on incorporating multipoint estimates for individual activity durations in the same way PERT does.

The Program Evaluation and Review Technique (PERT) is specifically designed to use multipoint estimates, typically three-point estimates (optimistic, pessimistic, most likely), to calculate activity durations and project completion probabilities. PERT accounts for uncertainty in activity durations by assigning a weighted average based on these multiple estimates, which is a core characteristic when multipoint estimation is deemed appropriate.

The Critical Path Method (CPM) traditionally uses single-point estimates for activity durations, making it less suitable than PERT when multipoint estimates are preferred.
