PK0-004 Question #171: Real Exam Question with Answer & Explanation
The correct answer is C: Crash the schedule.. When budget is not a constraint and schedule must be compressed, crashing the schedule by adding resources is the correct approach.
Question
A project manager does not have enough time to complete several tasks on a critical path. The budget is a low concern. Which of the following should be used to complete the tasks on time?
Options
- AFast-track the tasks.
- BUtilize positive float.
- CCrash the schedule.
- DRemove the critical path
Explanation
When budget is not a constraint and schedule must be compressed, crashing the schedule by adding resources is the correct approach.
Common mistakes.
- A. Fast-tracking overlaps tasks that are normally done sequentially, reducing schedule duration without additional cost - it is the preferred method when budget is constrained, not when budget is irrelevant.
- B. Positive float refers to the slack time available on non-critical tasks before they affect the project end date, and it cannot be applied to compress critical path task durations.
- D. The critical path cannot be removed; it is the longest sequence of dependent tasks that defines the minimum project duration and always exists in any network schedule.
