What is a PERT Chart and how does it differ from a GANTT Chart?

A PERT (Program Evaluation Review Technique) Chart is a project management tool that provides a graphical representation of a project's timeline. It allows for the analysis of the tasks involved in completing a given project, including the time needed to complete each task and the dependencies between tasks. On the other hand, a Gantt Chart is a type of bar chart that illustrates a project schedule. It shows the start and finish dates of the terminal elements and summary elements of a project. The key difference between a PERT chart and a Gantt chart is the way they present information. While a Gantt chart presents a linear representation of tasks, a PERT chart presents tasks in a network diagram to show their interdependencies.

Question was asked on:

However, even the tasks you do plan for can hold your project back. That's because many tasks are dependent on one another - even those that don't happen in order. A PERT Chart is a visualization that tracks these various tasks in a freeform flowchart to show their dependency on one another with arrows. Instead of a GANTT Chart that flows left to right in a timeline format, tasks might not be solely sequentially dependent, as you might have to go back and repeat work on one task that changes a future task and vice versa. The arrows also dictate whether something is directly connected versus dependent without resources. Dependent without resources refers to when the tasks aren't connected to each other but still relate. (Slide 5)
