PK0-004 Question #750: Real Exam Question with Answer & Explanation
The correct answer is B: Determine the critical path.. Building a project schedule from a network diagram requires identifying dependencies and durations before dates can be set, and the critical path can only be calculated after all prior steps are complete.
Question
A project manager has laid out a network diagram and is beginning to schedule activities for an upcoming project. Which of the following activities should be performed LAST?
Options
- ADetermine the start/finish dates.
- BDetermine the critical path.
- CDetermine the dependencies.
- DDetermine the task durations.
Explanation
Building a project schedule from a network diagram requires identifying dependencies and durations before dates can be set, and the critical path can only be calculated after all prior steps are complete.
Common mistakes.
- A. Start and finish dates are calculated after dependencies and durations are established, so they come before the critical path is determined, not last.
- C. Dependencies must be identified first to build the network diagram structure; they are the earliest step in the scheduling sequence.
- D. Task durations are estimated after dependencies are known but before dates or the critical path can be calculated.
