Advantages and disadvantages of PERT

Here we discuss the advantages and disadvantages of PERT but let’s know some basic information about PERT.

Program Evaluation and Review Technique (PERT) is a statistical tool which mainly used in project management. It is designed to analyze a project. PERT was invented by the US Navy.

Advantages and disadvantages of PERT

Since PERT is the most important tool but there are some advantages and disadvantages of PERT which are described below:

Advantages of PERT

1. PERT (Program Evaluation and Review Technique) compels managers to plan, which helps them see how the pieces fit together.
2. Each subordinate manager has to plan the events for which he or she is responsible.
3. It concentrates on critical elements that may need correction.
4. It makes possible a kind of forward-looking control.
5. The network system with its subsystems enables managers to aim reports and pressure for action at the right spot and level in the organization structure at the right time.

Disadvantages of PERT

1. Because of its emphasis on “activity-time” to its operation, PERT is not useful when no reasonable estimates of time schedule can be made.
2. Another disadvantage has been its emphasis on time only but not on costs.

PERT (Program Evaluation and Review Technique) is useful, but not a cure-all. However, it does not do the planning, although it forces planning.

It does not make control automatic, although it establishes an environment when sound control principles can be appreciated and used. And it apparently involves rather fewer expenses that one might expect.
