INTRODUCTION
• PERT was developed in the late 1950 by the US Navy submarine missile
programme and was applied in 1958.
• PERT shows the time taken by each component of project & the total time
required for its completion.
• PERT breaks down the project into events, activity& lays down their proper
sequence relationship & duration in the form of network.
• PERT is a technique of representing project plan in network.
• This is represented in a graphic form known as network diagram.

DEFINITION
The programme or project evaluation and review technique commonly
abbreviated as PERT, is a statistical tool, used in project management,
which was designed to analyse and represent the tasks involved in
completing a given project & to illustrate the flow of events in a project.

TYPES
• There are two types of network diagram,
Activity On Arrow(AOA):
In the first variant the duration is denoted on arrow
connecting diagram nodes, such diagram type called AOA.
Activity On Node (AON):
In such diagram the information about the task
duration is denoted in the diagram node & each task is
represented in the form of rectangle with definite set of fields.

NEED OF PERT
Prediction of deliverables
Planning resource requirement
Controlling resource allocation
Internal programme review
Performance evaluation
Uniform wide acceptance
Reduction in cost
Saving time
Determination of activities
Elimination of risk in complex
activities
Flexibility
Evaluation of alternatives
Useful effective control
Useful decision making
Useful research work

PROCESS
PERT Planning involve the following steps:

1. Identity Activities & Events:
• The activities are tasks require to complete the project.
• The events marking the beginning & end of one or more
activities.
• It is helpful to list the tasks in a table that in later steps can be
expanded to include on sequence is duration.
