Activity Network Diagram Critical Path. Once you ve identified all tasks and their dependencies it s time to create a network diagram also known as a critical path analysis chart. Critical path analyses are presented using circle and arrow diagrams.
The number shown in the left hand half of the circle allows you to identify each one easily. Some activities will depend on the completion of others. Plot the activities as a circle and arrow diagram.
In these circles show events within the project such as the start and finish of tasks.
Key steps in critical path method step 1. Next calculate the length or duration to complete each path by adding up the duration of all activities along that path. In this step the correct activity sequence is established. The activity network diagram an activity network diagram is a diagram of project activities that shows the sequential relationships of activities using arrows and nodes.
