What advantage does PERT/CPM provide in project management?

The advantage that PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) provides in project management is their ability to help highlight relationships among project activities. These methodologies are designed to map out the various tasks involved in a project and illustrate how they are interconnected. By visualizing these relationships, project managers can identify the sequence of activities, their dependencies, and the potential impact of delays on the overall project timeline.

This detailed mapping allows teams to focus on the critical path— the sequence of tasks that determines the minimum project duration. Understanding these relationships is crucial for effective project planning, scheduling, and resource allocation, as it enables project managers to identify tasks that can be completed in parallel as well as those that cannot be delayed without affecting the project's completion date. Consequently, PERT/CPM becomes an essential tool for driving efficiency, maintaining schedules, and successfully managing project scope.
