Network Diagram

In Plain English

A flowchart that shows the logical order and dependencies between all project activities.

Definition

A network diagram is a graphical representation of the logical relationships between project activities in a CPM schedule, showing predecessor-successor dependencies and the flow of work from project start to completion. The Activity-on-Node (AON) format is standard in modern scheduling software. Network diagrams are used to perform forward and backward pass calculations to determine early/late dates and float.
