program evaluation and review technique (PERT) Project management technique that shows the time taken by each component of a project, and the total time required for its completion. PERT breaks down the project into events and activities, and lays down their proper sequence, relationships, and duration in the form of a network.
While CPM is easy to understand and use, it does not consider the time variations that can have a great impact on the completion time of a complex project. The Program Evaluation and Review Technique (PERT) is a network model that allows for randomness in activity completion times.PERT was developed in the late 1950's for the U.S. Navy's Polaris project having thousands of contractors.It has the potential to reduce both the time and cost required to complete a project.ince the critical path determines the completion date of the project, the project can be accelerated by adding the resources required to decrease the time for the activities in the critical path. Such a shortening of the project sometimes is referred to as project crashing.
