Gantt and PERT Chart are two types of charts that are used by most project managers when embarking on a particular project. Both are used for a number of things, such as task scheduling, administering, control, and many other things that are needed for the smooth completion of a particular project.

However, there are some differences between the two. PERT is the short form of the Program Evaluation and Review Technique. This chart was first developed in 1950 by the United States Navy. In the event that you have a very complex task to accomplish, PERT charts are mostly used.

The various tasks that are needed to be done in a project are clearly represented using a PERT chart; it usually starts with a central node, which later divides into many others. On the other hand, the Gantt chart was first introduced by Charles Gantt in 1917 in order to help project managers show the proper sequence of all the tasks to be done in a project. Gantt chart reveals how much time it will take a project to be completed.

If in case you are not familiar with these, these are known to be two types of charts that are available. The PERT chart is known to be effective for creating network diagrams, while the Gantt chart is known to be a bar chart. You should first know what PERT means.

This stands for Program Evaluation and Review Technique. This chart has been created back in the 1950s and has been used ever since for trying to gauge the amount of time needed to complete the project. A Gantt chart was created during the first world war. The main goal of this is to test how long it will take for a project to be completed in a certain amount of time.
