Answer:
AON (Activity-on-Node) is a project management approach used to identify a project's key route, predecessors, and successors. It includes displaying project-related activities as nodes and the dependencies between them as arrows.
Step-by-step explanation:
To Evaluate the tasks that need to be finished before a certain activity can begin to determine ancestors using AON. The predecessors are these earlier actions. You can quickly determine a node's forebears by looking at the arrows that go to it.
Similar to this, when identifying successors, search for actions that can only begin when a given activity is finished. These are the subsequent actions. A node's successors may be found by looking at the arrows coming from it.
The critical path, which is the longest path through a project network, shows how long it will take to finish the project in total. It is calculated by first identifying the activities that do not have any successors, then going backwards across the network and figuring out when each activity started and ended.
