A critical path activity is delayed by 3 days due to material delivery issues. How does this affect the overall project completion?
Correct Answer
A) Project is delayed by 3 days
Any delay to a critical path activity directly delays the project completion by the same amount since critical path activities have zero float.
Why This Is the Correct Answer
Critical path activities are those that determine the minimum project duration and have zero float or slack time. When any activity on the critical path is delayed, there is no buffer time to absorb the delay, so the entire project completion date is pushed back by exactly the same amount. Since the material delivery delay affects a critical path activity by 3 days, and there is no float to absorb this delay, the project completion is delayed by exactly 3 days.
Why the Other Options Are Wrong
Option B: No effect on project completion
This is incorrect because critical path activities have zero float, meaning any delay directly impacts project completion. If this were a non-critical activity with sufficient float, then there might be no effect, but critical path delays always affect the project end date.
Option C: Project is delayed by less than 3 days
This is incorrect because critical path activities have zero float time to absorb delays. The delay cannot be less than the actual delay experienced since there is no buffer time available to reduce the impact on the overall project timeline.
Option D: Project is delayed by more than 3 days
This is incorrect because the delay to project completion equals exactly the delay to the critical path activity, not more. Additional delays would only occur if the delay caused other activities to become critical or if there were cascading effects, which is not indicated in this scenario.
Memory Technique
Think 'Critical = No Cushion' - critical path activities have no time cushion (float) to absorb delays, so delays pass directly through to project completion
