In scheduling terminology, which method represents activities on nodes and is commonly used with dependency types such as finish-to-start?

• A. Arrow Diagramming Method (ADM)
• B. Precedence Diagramming Method (PDM)
• C. Activity-on-Node (AON)
• D. Activity-on-Arrow (AOA)

Answer: (C)

Activities on nodes is the approach that places each activity as a node, with the sequencing relationships drawn between those nodes. This is the contemporary way to diagram schedules, known as the Activity-on-Node representation and it underpins the Precedence Diagramming Method. It naturally accommodates multiple dependency types, including finish-to-start (one activity must finish before the next starts) as well as start-to-start, finish-to-finish, and start-to-finish. The other common diagramming method places activities on arrows, which is less flexible for expressing these varied dependencies. So the correct concept is Activity-on-Node.
