Which network scheduling method shows the sequences and interdependence of activities, highlighting the shortest time path for completion?

The method that shows the sequences and interdependence of activities while highlighting the shortest time path for completion is the Critical Path Method (CPM). This scheduling technique is specifically designed to determine the longest sequence of dependent tasks and calculate the minimum time required to complete a project. By identifying the critical path, it becomes clear which activities are essential for project completion and which can be delayed without affecting the overall timeline.

In contrast, a Gantt Chart is primarily a visual representation of a project schedule, illustrating the start and finish dates of various tasks but not explicitly showing the interdependencies between them or the critical path. The Work Breakdown Structure (WBS) offers a hierarchical breakdown of project tasks but does not provide scheduling or time analysis. The Program Evaluation and Review Technique (PERT) is also used for project scheduling, particularly in complex projects, but it focuses on uncertainties in task durations rather than the straightforward identification of the critical path.

Overall, the Critical Path Method is crucial for project managers to optimize resource allocation, minimize delays, and ensure timely project delivery, which is why it is the correct choice in this context.
