What is the purpose of a PERT chart in project management?

A PERT chart, which stands for Program Evaluation Review Technique, is primarily used to visualize and sequence project tasks. This visual representation allows project managers and team members to see the project schedule, identify the order of tasks, and understand the relationships among them. By laying out the tasks involved in a project, along with their durations and dependencies, a PERT chart helps in assessing the timeline and critical path necessary for project completion.

The ability to visualize tasks in this way is crucial for effective planning and scheduling, as it highlights how delays in one task can impact subsequent tasks. This aids in better decision-making and resource allocation, enhancing the overall efficiency of project management.

While options regarding calculating costs, assigning resources, and evaluating project performance are related to various aspects of project management, they do not directly pertain to the primary function of a PERT chart. The focus of a PERT chart is on task visualization and sequencing, which is essential for outlining the project’s workflow and ensuring timely completion.
