Activity On Arrow (AOA)

1 Definition

Network diagramming technique in which activities are represented by arrows. The tail of the arrow represents the start of the activity; the head of the arrow represents the finish of the activity. The length of the arrow does not represent the expected duration of the activity. Activities are connected at points called nodes (usually drawn as circles) to illustrate the sequence in which activities are expected to be performed. Also called precedence diagramming method (PDM).
