What is another term for an activity network diagram?

An activity network diagram, also known as an arrow diagram, is a visual representation used in project management to illustrate the sequence of activities and the dependencies between them. This diagram typically employs arrows to represent tasks and lines to indicate the flow of the project. It helps in identifying the critical path, which is crucial for effective scheduling and resource allocation.

While flowcharts depict processes and the flow of decisions, they do not specifically represent the relationships between various activities in a network format. Matrix charts are structured to compare relationships between different entities and do not focus on the temporal relationships of activities. Decision trees visually display choices and potential impacts of decisions but do not specifically document the sequencing of project activities as an activity network diagram does. Therefore, the term "arrow diagram" distinctly captures the essence of the activity network diagram, emphasizing the connections and sequence of activities within a project.
