Network Technique

Ø  Network technique is also known as program evaluation and review technique (PERT) and critical path method (CPM). Program evaluation and review technique and Critical path method are popular network technique used to plan and control time and cost of a project. It is very must useful in planning, implementing, monitoring and controlling phase of project. The purpose of PERT is to develop a network of activities and their interrelationship to highlight critical time intervals that affect the overall project. PERT is a planning tool that use a network to plan projects involving numerous activities and their interrelationship CPM is the longest path in which the project can be completes in shortest time.

# Steps in PERT

1.       Identify the activities to be performed and events the will mark their completion.

2.       Develop a network showing the relationship among the activities and events.

3.       Calculate the time needed for each event and the time necessary to get from each event to the next.

4.       Identify within the network the longest path that leads to completion of the project. This path is known as critical path.

5.       Refine the network.

6.       Use the network to control the project.
