CAPM Practice: Demonstrate an understanding of a project management plan schedule

The Precedence Diagramming Method (PDM) network diagram explicitly shows all logical relationships (FS, SS, FF, SF) between all activities, revealing the full project logic. While Gantt charts show dependencies, they provide less visual clarity on complex relationships. The network diagram is the foundational tool for identifying the critical path and all activity dependencies.

**Why not B:** A milestone list identifies key project events and dates but does not show the logical relationships or dependencies between activities. Milestones mark significant points but do not reveal the sequencing logic that connects project activities.

**Why not C:** A Gantt chart shows activities plotted against a timeline and can display some dependencies, but it is primarily a scheduling and communication tool. It does not provide the same level of clarity on complex logical relationships (such as SS, FF, and SF dependencies) as a network diagram.

**Why not D:** A resource histogram shows resource allocation and utilization over time. It is a resource management tool that does not display logical relationships between activities — it focuses on when and how much of each resource is needed.
