'''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.

==Usage==

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.

Line 17 ⟶ 22:

* A node is a specific, definable achievement in the project.

* It has zero duration and consumes nil resources.

* All activities that lead into a node must be completed before the activity lines following this node can start.
