Explanation:
An 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.

The ADM is also known as the activity-on-arrow (AOA) method, it only show finish-to-start relationship. ADM network drawing technique the start and end of each node or event is connected to an arrow.

The start of the arrow comes out of a node while the tip of the arrow goes into a node. Between the two nodes lies an arrow that represents the activity.

* The event represented by the circular node consumes neither time nor resources.
* 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 lies following this node can start.
