An activity network diagram is a graphical representation of the logical relationships and dependencies among project schedule activities. One of the methods used to create these diagrams is the Arrow Diagramming Method (ADM). In ADM, activities are represented by arrows, and the nodes or circles at each end of the arrow represent the start and end events (milestones). Due to this graphical convention, the ADM technique and the resulting diagrams are commonly referred to as arrow diagrams.

Scheduling Techniques

p. 468: "The two most common techniques for network construction and analysis are the program evaluation and review technique (PERT)

which is an event-oriented network

and the critical path method (CPM)

which is an activity-oriented network... PERT networks are also called arrow diagrams."
