PK0-005 Practice Question: A construction project is underway, and the…
A construction project is underway, and the project manager is using a Gantt chart to track progress. The project is divided into five phases: Foundation, Framing, Plumbing, Electrical, and Finishing. The project manager notices that the Framing phase is behind schedule because of a delayed material shipment. The Gantt chart shows that Framing has a predecessor of Foundation and a successor of Plumbing. The project manager updates the Gantt chart to reflect the delay. Which action should the project manager take next?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Recalculate the critical path to determine impact on finish date
When a delay occurs on a task (Framing) that is on the critical path (as it has predecessor and successor dependencies), the critical path may be affected, so recalculating the critical path is necessary to determine the impact on the project finish date. Option B is incorrect because adding a buffer to Plumbing without analyzing the overall schedule impact is premature and not a systematic response. Option C is incorrect because crashing (adding resources) should be considered only after assessing the critical path and determining if compression is needed. Option D is incorrect because informing stakeholders without first analyzing the impact is incomplete; the project manager should first understand the effect before communicating.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Recalculate the critical path to determine impact on finish date
Why this is correct
Correct. Recalculating the critical path allows the project manager to assess the impact of the delay on the overall project finish date and make informed decisions.
- ✗
Add a buffer to the Plumbing phase
Why it's wrong here
Incorrect. Adding a buffer to Plumbing does not address the root cause and may not be necessary; the impact on the critical path must be analyzed first.
- ✗
Crash the project by adding resources to Framing
Why it's wrong here
Incorrect. Crashing should be considered only after evaluating the critical path and determining that schedule compression is warranted; it is not the immediate next step.
- ✗
Inform stakeholders that the timeline has been updated
Why it's wrong here
Incorrect. Informing stakeholders is important but should come after analyzing the impact of the delay; otherwise, communication may be incomplete or inaccurate.
