Many project managers use the PDM to create a specific type of project network diagram.  In a PDM diagram:


Although a precedence diagram has specific information, such as predecessor, successor, and duration, written on each box, it is different from a conventional flow diagram.  It cannot, for example, contain loops, because this would require moving backward in time.

Each box in a precedence diagram represents an activity at the WBS work element level; these boxes are called nodes.  Nodes are linked by arrows that show the nature of the relationship between predecessor and successor activities.
