Which method allows project managers to visualize task dependencies?

The critical path method (CPM) is specifically designed to identify and visualize task dependencies in a project. By defining the sequence of activities required to complete a project and determining which tasks are dependent on others, project managers can effectively map out the critical path—the longest stretch of dependent activities that dictates the project's minimum completion time.

While Gantt charts are valuable for visualizing project schedules and timelines, they primarily depict start and end dates for tasks rather than direct dependencies among them. PERT analysis is similar to CPM but is more focused on uncertainty and estimating time rather than establishing clear dependencies. A work breakdown structure (WBS) organizes project tasks into a hierarchical structure but does not visually represent how those tasks are interrelated concerning their sequence and dependencies.

Thus, the critical path method stands out as the most effective approach for visualizing task dependencies, allowing project managers to prioritize resources and manage timelines effectively.
