Which network schedule uses the Activity-on-Node method?

• A. Gantt Chart
• B. Critical Path Method
• C. Arrow Diagram Method (ADM)
• D. Precedence Diagramming Method (PDM)

Answer: (D)

In network scheduling, how each activity is represented is the key idea. Activity-on-Node means every activity is a node, and the dependencies between activities are shown with directed connections between those nodes. This is the Precedence Diagramming Method. It’s the standard way in modern project planning to build the network: you place a node for each activity and link them to reflect finish-to-start or other relationships (FS, SS, FF, SF). This setup lets you trace the sequence, identify the critical path, and calculate floats. The other formats don’t fit this description. A Gantt chart is a timeline visualization, not a network diagram. The Arrow Diagram Method represents activities as arrows and uses nodes for events, which is the opposite of AO N. The Critical Path Method is the technique you use to determine the longest path and schedule, and it can be implemented with different diagram styles, but the specific Activity-on-Node representation is characteristic of the Precedence Diagramming Method.
