A project network diagram is a flow chart depicting the sequence in which a project’s non-summary activities (“terminal elements”) are to be completed, showing all their dependencies.
The network diagram is excellent for planning and replanning project activities sequencing, and it also identifies the project’s critical path. Upon completing the construction of the network diagram, the activities which represent the longest path from project start to project end, are identified. That means if any of these critical path activities slip, so does the project completion date.
