PERT is a technique used for which one of the following?

PERT, which stands for Program (or Project) Evaluation and Review Technique, is a sophisticated project management tool developed in the 1950s [t1]. It is primarily used for planning, scheduling, and coordinating complex projects, especially those where the time required for individual tasks is uncertain [t1][t2]. Unlike the Critical Path Method (CPM), which uses fixed time estimates, PERT employs a probabilistic approach using three time estimates: optimistic, pessimistic, and most likely [t2][t4]. This allows project managers to calculate expected durations and identify the critical path while accounting for potential risks and variability [t3][t4]. It is widely applied in diverse fields such as construction, research and development, and innovative product launches to ensure projects are completed within budget and on time [t2][t3].
