Difference between Gantt and PERT Chart

In the project management world, there are two main types of charts that are used to visualize the progress of a project: Gantt and PERT. Both have their own strengths and weaknesses, but which one is right for your project? Let’s take a look at the difference between Gantt and PERT charts.

What is Gantt Chart?

Gantt charts are a popular project management tool for planning and scheduling projects. A Gantt chart \ ids each task in a project as a horizontal bar that extends from the start date to the end date. The length of the bar indicates the duration of the task, and the position of the bar indicates when the task should start and finish. Gantt charts also typically include a vertical axis that lists all of the tasks in the project, as well as other important information such as deadlines, assigned resources, and task dependencies. By using a Gantt chart, project managers can quickly see which tasks need to be completed in order to meet the project’s goals.

What is PERT Chart?

PERT stands for Program Evaluation Review Technique. It is a statistical tool used to predict the amount of time needed to complete a project, broken down into its individual tasks. The PERT Chart was originally developed by the U.S. Navy in the 1950s, as a way to manage the construction of nuclear submarines. Today, it is widely used in a variety of industries, from construction to software development.

PERT charts are particularly useful for large projects with many moving parts, as they provide a clear overview of the different tasks and their interdependencies. PERT charts can also be used to identify potential bottlenecks and to plan for contingencies. In short, PERT charts are an essential tool for any project manager looking to finish on time and on budget.

Difference between Gantt and PERT Chart

Gantt and PERT charts are two of the most popular tools used for project management. While they both have their advantages, there are some key differences between the two.Gantt charts are typically used for more straightforward projects with well-defined tasks. This makes them ideal for projects that can be completed relatively quickly and with a limited number of people. In contrast, PERT charts are more suited for larger and more complex projects.

This is because PERT charts allow for more flexibility in task order and timing. As a result, PERT charts can help to avoid potential Bottlenecks that can occur with Gantt charts.Ultimately, the choice of which chart to use depends on the specific project requirements. However, both Gantt and PERT charts can be useful tools for managing projects effectively.


The Gantt chart is a more popular tool, but the PERT chart can be more effective when it comes to project management. It’s important for business owners and project managers to understand the difference between these two tools so they can choose the right one for their needs.
