The principle that indicates the minimum duration of a project in the Program Evaluation and Review Technique (PERT) is the critical path. The critical path comprises the sequence of dependent tasks that determine the longest stretch of necessary activities and the minimum time required to complete the project. Any delays in the critical path directly affect the project's overall completion time, emphasizing its importance in project management.

Understanding the critical path allows project managers to identify which tasks must be completed on time to ensure that the project stays on schedule. This concept is central to effective project planning and helps in prioritizing tasks, allocating resources, and managing timelines efficiently. In contrast, lag time refers to the delay between tasks, lead time involves overlapping activities or shortening delays, and fast track means scheduling tasks to occur simultaneously to expedite the project, none of which define the minimum duration of the project as effectively as the critical path does.
