Part 187: Project Schedule Network Diagrams
(OUTPUT Project Schedule Management: Sequence Activities)
- A PROJECT SCHEDULE NETWORK DIAGRAM = graphical representation of logical relationships (dependencies) between the project’s activities
- Can be produced manually, or via project management software
- Can be detailed or broad
- Can include a summary narrative
- Narrative describes the diagram and approach used to develop the sequence
- Unusual activity sequences should be described in the narrative
- When an activity has multiple predecessors, we say that we have a Path Convergence. For example, we manufacture the tires, the engine, and the seats in the predecessor activities. These three activities converge into the assembly of the vehicle.
- When an activity has multiple successors, we say that we have a Path Divergence. For example, we produce rubber in one activity. This rubber is sent to manufacture tires, weather seals for the vehicle doors, and seals for the engine valves.
- Divergence and Convergence create higher risks, because one activity is affected by, or can affect multiple activities
