PERT

Abstract

The program (or project) evaluation and review or PERT is a statistical tool designed to analyze and represent the tasks involved in completing a given project. It is used in project management and commonly together with the critical path method or CPM to control, plan and schedule.

This project management method is used for analyzing all the tasks involved in completing a project focusing on dealing with completion time rather than the costs of the project. It incorporates details about all the task such as their duration and required finished activities, also managing the uncertainty of the complete duration of each task.

PERT and CPM are often used together due to the fact that they complement each other, while CPM uses one time and one cost estimation, PERT uses three time estimates, but no costs for each activity. However, PERT use has been increasingly applied to all CPM scheduling.[1]
