What is the purpose of using the Program Evaluation Review Technique (PERT) chart?

The purpose of using the Program Evaluation Review Technique (PERT) chart is fundamentally about project scheduling and management, particularly dealing with uncertainty in task durations. PERT is a statistical tool that helps project managers visualize the timeline of project activities.

The primary advantage of PERT charts is that they allow project managers to estimate the minimum time required to complete a project when the time estimates can vary. This is achieved by calculating different task duration scenarios—optimistic, pessimistic, and most likely—and then using these estimates to create a comprehensive view of when tasks should start and finish.

Consequently, converting task durations into actual dates on a project calendar aligns directly with PERT's capabilities. By detailing the sequence of tasks and their dependencies, a PERT chart gives the necessary insight to set realistic timelines that reflect the project’s actual schedule. This facilitates planning and helps prevent delays in project execution.

The other options illustrate different aspects of project management but do not align directly with the core purpose of PERT charts. Evaluating project quality, identifying stakeholders, and assessing financial risks are essential tasks within project management, yet they are not the primary function of PERT charts. Instead, PERT is specifically designed to handle time management and scheduling complexities, making option B the
