- The Precedence Diagramming Method (PDM), also called Activity-on-Node (AON), uses boxes or nodes to represent activities and arrows to show logical relationships (dependencies) between them. PDM supports all four relationship types: FS, FF, SS, and SF. It is the most commonly used network diagramming method in modern project management. ADM (Activity-on-Arrow) places activities on the arrows instead.
