Exercise 1: Draw a Precedence Diagramming Method (PDM) (a visual representation technique that depicts the activities involved in a project ) and calculate the critical path.

Precedence Diagramming Method (PDM) is a graphical representation technique. It shows the inter-dependencies of activities and is used in schedule development. The other name for this technique is Activity on Node (AON).

We use this method in drawing the project schedule network diagrams; for example, critical path network, critical chain network diagram, and others.

The Precedence Diagramming Method shows activity relationships. Hence, it is an important communication tool for stakeholders.
