'''Arrow diagramming method''' (ADM) is a network diagramming technique in which activities are represented by arrows.<ref>CPM in Construction – A Manual for General Contractors(Copyright 1965 by the Associated General Contractors of America)</ref> ADM is also known as the activity-on-arrow (AOA) method.

Line 8 ⟶ 6:

ADM is used for scheduling activities in a [[project plan]]. Precedence relationships between activities are represented by circles connected by one or more arrows. The length of the arrow represents the duration of the relevant activity. ADM only shows finish-to-start relationships, meaning that each activity is completed before the successor activity starts.

Sometimes a "dummy task" is added, to represent a [[dependency (project management)|dependency]] between tasks, which does not represent any actual activity. The dummy task is added to indicate precedence that can't be expressed using only the actual activities. Such a dummy task often has a completion time of 0.
