Network Path
An ordered chain of activities linked by dependencies within a project schedule network diagram.
Key Points
- A network path is a contiguous sequence of activities connected by dependency relationships.
- Paths can run from the project start (or a predecessor) to the project finish (or a milestone).
- The longest network path is the critical path and sets the overall project duration.
- Float and schedule risk are evaluated by examining and comparing different network paths.
Example
In a software project, one path might be: Define Requirements -> Design -> Develop -> Unit Test -> Integration Test. These tasks form a single network path because each depends on the completion of the previous one.
PMP Example Question
During schedule development, the PM identifies Design -> Code -> Unit Test -> Integration Test as a continuous set of dependent activities. What is this set called?
- Work package
- Network path
- Activity list
- Milestone sequence
Correct Answer: B — a chain of dependent activities in the network diagram
Explanation: A network path is an ordered set of activities connected by dependencies; the other options do not represent a dependency-linked sequence.
