Arrow diagramming method
 | The topic of this article may not meet Wikipedia's general notability guideline. (September 2009) |
Arrow Diagramming Method (ADM) is a network diagramming technique in which activities are represented by arrows.
It is used for scheduling activities in a project plan.
The precedence relation between activities is represented by circles connecting to one or more arrows. The length of the arrow represents the duration of the relevant activity.
Sometimes a "dummy task" is added, to represent a dependency between tasks, which does not represent any activity.
Use of the Arrow Diagramming Method as a common project management practice has declined with the adoption of computer-based scheduling tools. The Precedence Diagram Method (PDM) is often favored over the Arrow Diagraming Method.
The Arrow Diagramming Method is also known as the Activity-on-Arrow (AOA) method.
