What is Program Evaluation and Review Technique (PERT)?

Last Updated on December 5, 2020 by Admin

The program evaluation and review technique is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project. Read more to know more about the program evaluation and review technique – PERT and how the PERT chart is a useful project management tool in the construction project.

Program Evaluation and Review Technique (PERT) is a method used to examine the tasks that are in a schedule and determine a variation of the Critical Path Method (CPM). It analyzes the time required to complete each task and its associated dependencies to determine the minimum time to complete a project.

What is PERT?

The Program Evaluation Review Technique, or PERT, is a project management tool used in project planning to calculate the amount of time it will take to realistically finish a project. Using the technique helps project planners identify the start and end dates, as well as interim required tasks and timelines. The information is displayed as a network in chart form.



PERT charts are tools used to plan tasks within a project – making it easier to schedule and coordinate team members accomplishing the work. PERT charts were created in the 1950s to help manage the creation of weapons and defense projects for the US Navy.

While PERT was being introduced in the Navy, the private sector simultaneously gave rise to a similar method called Critical Path.

PERT is similar to the critical path in that they are both used to visualize the timeline and the work that must be done for a project. PERT is one of the best project management tools used in construction scheduling.

However with PERT, you create three different time estimates for the project: you estimate the shortest possible amount of time each task will take, the most probable amount of time, and the longest amount of time tasks might take if things don’t go as planned. PERT is calculated backward from a fixed end date since contractor deadlines typically cannot be moved.
