A Comparative Study Between Gantt Chart & Pert Chart

A chart wise decomposition of work of a project will be helpful makes it much easier to be done. There are various kinds of management tools one can use to understand and complete the work at hand. Gantt chart and Pert Chart are two such graphical tools used for project management which help you with scheduling and organising your project.

Gantt Chart and Pert Chart are very similar to each other yet there are some differences as well. Here is a comparative study between the two that will help you to understand how they work.

  • Pert Charts a.k.a Program Evaluation and Review Technique charts, are created to analyse the work at hand. These charts also help to estimate the least amount of time that one can take to finish it. Whereas, Gantt Charts assist you to coordinate and track the progress of the work in hand. To make your work easier, there are Gantt chart maker tools that allow you to build Gantt chart online for free.
  • Pert Charts are used to break down, plan and schedule the time of a project before the beginning of the project. It helps in analysing the task and estimation of how much time it might take to complete the project. These charts also help to understand time estimation for tasks individually. Gantt Chart, on the other hand, helps you to determine the timeline while the work is being done. It is the estimation of how much time is actually needed for the work to be completed.

  • Pert Charts do not give you exact timelines of the project since these are based on hypothetic grounds. So, a Pert Chart will only allow you to administer your project and schedule it according to priority. Gantt Charts will give you the exact timeline of you work progress. These charts will emphasize and show how much work has been completed in the estimated time.
