Activity on Arrow Explanation:

The planning phase of a project involves listing and organizing all the project related activities in to a diagram. That diagram is called network diagram. A network diagram involves some principles that should be considered while developing it. Network diagrams can be made using different types of formats. One of the format that can be used is called Activity on arrow (AOA). In this format, every activity of the project is showed by an arrow and the description of the activity is written above the arrow. The activities are linked together by circles, called events, which show the start and end of each activity. A unique number is assigned to each event. The events establish the precedence relationship of the activities.
