What are some of the advantages in the use of AOA notation as opposed to AON? Under what circumstances does it seem better to apply AON methodology in network development? Solution AOA means activity on arc. In network diagrams AOA notation uses arrow diagram where each activity is represented by an arrow joining 2 circles (nodes). The circles or the nodes represents the transition between activities, which are called events. AON means activity on node. Here activities are represented by circles and the arc represents the events. The advantage of using AOA as opposed to AON is that AOA is more suitable for analytical techniques. Path tracking in case of AOA is simplified by event numbering. Lastly key events are easy to identify. AON is better under the following circumstances:.

Solution
AOA means activity on arc. In network diagrams AOA notation uses arrow diagram where each
activity is represented by an arrow joining 2 circles (nodes). The circles or the nodes represents
the transition between activities, which are called events.
AON means activity on node. Here activities are represented by circles and the arc represents the
events.
The advantage of using AOA as opposed to AON is that AOA is more suitable for analytical
techniques. Path tracking in case of AOA is simplified by event numbering. Lastly key events
are easy to identify.
