The activity network diagram aids in the efficient scheduling of a project. It delivers an estimate of how long it will take to accomplish a project in the least and maximum timeframes. The following Precedence Network Diagram diagram emphasizes the seventh of the New Seven Management Development Tools. The Activity Network Diagram is a tool that Project Managers use to show project activities and relationships in a visual format. The goal is to determine the best case, worst case, and most likely project completion times (critical path). Furthermore, to determine which key route activities have the most impact on project completion. Some jobs can be done simultaneously (in parallel), while others must wait until the others are finished (in series). Some actions may only need to be partially finished before moving on to the next.
