What type of diagram is often used to depict relationships between project tasks?

The dependency diagram is specifically designed to illustrate the relationships and dependencies between various tasks within a project. It helps project managers visualize which tasks must be completed before others can start, highlighting the sequence and interconnections between them. This is particularly useful for identifying critical paths, potential bottlenecks, and overall project flow.

In contrast, other diagrams serve different purposes. A flowchart is more geared towards depicting processes or workflows rather than task relationships, while an organizational chart shows the hierarchy and roles within a team or organization but does not connect tasks. A Gantt chart, on the other hand, is typically used for scheduling and visually tracking project timelines but does not explicitly focus on the relationships between tasks.
