Which project management tool helps in providing a visual display of all project tasks and their interdependencies?

The Network Diagram is the correct choice because it effectively illustrates the sequence of project tasks and their interdependencies. It visually represents the project activities as nodes connected by directed lines, highlighting which tasks must be completed before others can begin. This visual representation helps project managers identify the critical path, manage task scheduling, and optimize resources by showing the relationships between tasks clearly.

In contrast, the Critical Path Method focuses on identifying the longest path through the project, determining how delays in certain tasks can affect overall project timelines. The Work Breakdown Structure organizes project deliverables into manageable sections but does not illustrate task interdependencies. A Bar Chart, while useful for tracking the progress of tasks over time, does not provide a clear visual representation of how tasks are interconnected. Therefore, the Network Diagram stands out as the most effective tool for visualizing project tasks and their relationships.
