PERT

PERT is a well-known and widely used project scheduling technique used to create an activity timetable taking variability activity durations into account. It relies on principles borrowed from statistics such as the central limit theorem and the normal distribution (see “The Program Evaluation and Review Technique (PERT): Incorporating activity time variability in a project schedule”).

The Program Evaluation and Review Technique (PERT) is a project scheduling technique to analyze and represent the tasks involved in completing a given project. It incorporates activity duration variability and relies on similar concepts as the critical path method (CPM, see “The Critical Path Method (CPM): Incorporating activity time/cost trade-offs in a project schedule”).
