A project network illustrates the relationships between activities (or tasks) in the project. Showing the activities as nodes or on arrows between event nodes are two main ways to draw those relationships. With activities on arrow (AOA) diagrams‚ you are limited to showing only the finish-to-start relationships - that is‚ the arrow can represent only that the activity spans the time from the event at the start of the arrow to the event at the end. As well‚ "dummy" activities have to be added
