PERT (Program evaluation review technique)

PERT (Program Evaluation and Review Technique) is a method for analyzing the tasks involved in complex projects. It estimates the time needed for each task and identifies the shortest time to complete the whole project. PERT breaks the project into activities with sequential relationships. It estimates optimistic, pessimistic, and most likely durations for each activity to calculate the expected duration while accounting for uncertainty. The critical path is determined as the longest sequence of activities to identify the minimum time needed and activities that could delay completion. PERT charts are used to plan, schedule, and monitor project progress through updating.
