How do the building blocks of aon and aoa differ?

Answer 1

The building blocks of AON (Activity on Node) and AOA (Activity on Arrow) differ primarily in their representation of project activities. In AON, each activity is represented by a node (a point or circle), with arrows indicating the dependencies between activities. Conversely, AOA uses arrows to represent the activities themselves, while nodes represent the points where activities begin or end. This fundamental difference affects how project schedules and dependencies are visualized and managed in project management.
