‘PERT’ which is short for ‘Program Evaluation and Review Technique’ is an event-oriented planning aid. A PERT Chart is usually computerised and is used in order to estimate project duration when there is any hesitation in estimates of time duration for individual activities. It helps the project team to order the activities that must be completed so that a decision can be implemented.
The PERT Chart demonstrates the critical path of the project and the dependencies between the tasks and activities. The critical path helps the project team to identify the minimum set of tasks to be completed. This is called the critical set.
This may seem to be a contradiction in terms because you might think that the completing all tasks is required to complete a project. However, the critical path represents not the ideal set of tasks to be completed for your project but rather the minimum set. It is this path which you must go through in order to reach completion of your project on time.
Other tasks, while important to the overall completion, do not influence the final delivery for the project. These can, therefore, be rescheduled if time is tight or circumstances change. This being said, tasks on your critical path will affect the delivery time of the project and therefore should only be modified in extreme conditions.
What Are The Advantages Of A PERT Chart?
A PERT chart gives managers the opportunity to evaluate the time as well as resources which are required in order to manage a project. This evaluation encompasses the ability to track required assets during any stage of production during the course of the entire project.
