- A
Expedite the remaining tasks by adding more resources to critical chain tasks.
Why wrong: Expediting may help but first the PM should analyze why buffer is being consumed and address underlying issues.
- B
Analyze the reasons for the delays and implement corrective actions to prevent further buffer erosion.
Root cause analysis and corrective action are proactive steps to protect the project schedule.
- C
Add more buffer to the project schedule to accommodate the delays.
Why wrong: Adding buffer is a reactive approach and does not address root causes. It may also increase the project duration.
- D
Inform stakeholders that the project will likely be delayed and request additional time.
Why wrong: Communicating potential delays is important but should come after analysis and corrective actions are considered.
Quick Answer
The correct answer is to analyze the reasons for the delays and implement corrective actions to prevent further buffer erosion. This is because the critical chain method relies on a project buffer to protect the overall schedule against cumulative task delays; when buffer consumption outpaces planned progress, it signals that the underlying schedule is at risk and requires immediate root-cause analysis rather than simply monitoring the buffer. On the Project Management Professional PMP exam, this scenario tests your understanding of buffer management as a proactive control mechanism, often appearing in questions that contrast it with passive tracking—a common trap is to assume you should simply add more buffer or ignore the trend. A strong memory tip is to think of the buffer as a “canary in the coal mine”: if it’s being consumed too fast, you don’t just watch the canary; you fix the mine.
PMP Process — Managing Technical Aspects Practice Question
This PMP practice question tests your understanding of process — managing technical aspects. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your project is using a critical chain method. You have identified that the project buffer is being consumed faster than planned due to delays in several tasks. What should you do?
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
Analyze the reasons for the delays and implement corrective actions to prevent further buffer erosion.
The PM should analyze the root causes of the delays and take corrective actions to protect the buffer. This may involve resource reallocation or schedule compression techniques.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the PMP exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
