HKSM
Node
The point on a schedule network diagram where relationship lines join, usually depicting an activity or milestone.
Key Points
- Shows where dependencies attach to an activity or milestone.
- Used in precedence diagramming; relationships (FS, SS, FF, SF) connect at nodes.
- Often displays details such as activity ID, name, duration, and dates.
- Serves as the building block of the schedule network used for critical path analysis.
Example
In a website project, "Develop Backend" and "Test API" are nodes. A finish-to-start dependency line runs from "Develop Backend" and connects at the "Test API" node, indicating testing cannot start until development finishes.
PMP Example Question
In a precedence diagram, what does a node primarily represent?
- The connection point where dependencies link to an activity or milestone
- The total float available on the critical path
- A resource calendar constraint
- A detailed risk response plan
Correct Answer: A - The connection point where dependencies link to an activity or milestone
Explanation: A node is the point on the network diagram where dependency lines connect and typically represents an activity or milestone.
