Network Diagram for Activity On Node (AON) and Activity On Arrow (AOA) Technique.

There are two basic techniques to draw a network diagram for the activities of a project once their precedences are known.
AON - Activity on Node technique.
AOA - Activity on Arrow Technique.
There is not much difference between them. But in AON we represent the activity by the Node. While in AOA technique we represent the Activity on Arrow.
We also have to use the dummy activity at certain places in Activity on Arrow (AOA) method of network. This dummy activity does not take any resources or time but only helps in clarification of the relationship of the network diagram.
