Graphical evaluation and review techniques are essentially a first-generation PERT approach to scheduling, in which both the completion probabilities and activity costs to be built into a network representation are considered.

Question

Quizplus · Accepted Answer

Graphical Evaluation and Review Technique (GERT) allows for probabilistic treatment of both network logic and activity duration estimates, which is more advanced than the first-generation Program Evaluation and Review Technique (PERT) that primarily focuses on deterministic models and does not incorporate activity costs directly into the network model.
