Using the Arrow Diagramming Method

The arrow diagramming method (ADM) approach to activity sequencing uses arrows to represent the activities. The arrows are "connected" on nodes. ADM only uses finish-to-start relationships. In some instances, dummy activities are required to express the logical relationship between two activities. A dummy activity is illustrated with a dashed arrow between the nodes. The following illustration is a simple example of an ADM network diagram.

ADM is an example of "activity-on-arrow" (AOA) networks. This approach is not as popular as PDM, but may still be prevalent in some industries. ADM can be created manually or through a project management information system (PMIS).
