what do you know about PERT ?

 PERT (Program Evaluation and Review Technique)

 The program evaluation and review technique (PERT), a technique that evolved partly from the Gantt chart, is a scheduling tool that does emphasize the interrelationship of tasks.

But, what is meant by PERT?

It is a network of project activities showing both the estimates of time necessary to complete each activity and the sequence of activities that must be followed to complete the project.

The PERT network contains two primary elements, activities, and events.

 Activities are specified sets of behavior within a project, while events are the completions of major project tasks.

Within the PERT network, each event is assigned corresponding activities that must be performed before the event can materialize.

Steps in designing a PERT network

When designing a PERT network, managers should follow four primary steps:

 Step (1): Listing all the activities / events that needed to be accomplished for the project and the sequence in which these activities / events should be performed.

 Step (2): Determining how much time will be needed to complete each activity / event.

Step (3): Designing a PERT network that reflects all of the information contained in step (1) and (2).

 Step (4): Identify the critical path. We can show this in Figure 2.3 that represents a PERT network designed for building a house.
