Process for Creating AOA Diagrams
1. Find all of the activities that start at node 1: Draw their finish nodes and draw arrows between node 1 and those finish nodes; put the activity letter or name and duration estimate on the associated arrow
2. Continue drawing the network diagram, working from left to right: Look for bursts and merges
Bursts occur when a single node is followed by two or more activities
A merge occurs when two or more nodes precede a single node
3. Continue drawing the project network diagram until all activities are included on the diagram that have dependencies
4. As a rule of thumb, all arrowheads should face toward the right, and no arrows should cross on an AOA network diagram
Activities are represented by boxes
Arrows show relationships between activities
More popular than ADM method and used by project management software
Better at showing different types of dependencies
