todolist # 14 - Sequence the activities

Once we know the activities, the next step is to sequence them based on their dependencies. Dependencies can be either internal to the project or external. Mainly we use two techniques for activity sequencing;


1) Activity on node diagram (AON)




















a) On activity on node diagrams (AON) , activities are represented on the nodes


b) AON can represent four types of dependencies (finish to start, finish to finish, start to start, start to finish)


c) It is the most widely used





2) Activity on arrow diagrams (AOA)





a) On activity on arrow diagrams, the activities are represented on the arrows.


b) Activity on arrow diagrams can represent only finish to start dependencies


c) Not widely used
