Final answer:
Arrows on an Activity-On-Node (AON) project network represent dependency between activities.
Step-by-step explanation:
In the context of an Activity-On-Node (AON) project network, arrows represent dependency between activities. Each activity in the project has a specific order in which it must be completed, and the arrows show the sequence of activities.
For example, if Activity A must be completed before Activity B can start, there would be an arrow from A to B indicating the dependency. This means that Activity B depends on the completion of Activity A.
The arrows do not represent project flow or the activities themselves. They simply show the relationships and dependencies between the activities in the project.
