What Should a Scrum Master Do When Acceptance Criteria Are Unclear?
In a Scrum project, the development team is consistently missing sprint commitments. The daily standup reveals that they are blocked by unclear acceptance criteria. What should the scrum master do?
Quick Answer
The correct answer is to coach the product owner on writing clear acceptance criteria and ensure stories are refined before sprint planning. This is the right action because the scrum master serves as a servant-leader and process coach, not a task assigner; when the team misses sprint commitments due to unclear acceptance criteria, the root cause is a breakdown in backlog refinement, which the scrum master must address by guiding the product owner to define precise, testable conditions of satisfaction before the sprint begins. On the PMP exam, this scenario tests your understanding of the scrum master’s role in facilitating stakeholder collaboration and removing impediments at the process level, often appearing as a distractor where you might be tempted to have the scrum master rewrite the criteria themselves or simply tell the team to “try harder.” A common trap is confusing the scrum master with a project manager who directly fixes the work; instead, remember that the scrum master empowers others to improve. Memory tip: “Coach, don’t fix—teach the PO to write the mix.”
⚠ Common exam trap
Test-takers frequently confuse the Scrum Master's role as a facilitator with that of a problem-solver who directly removes technical blockers, rather than recognizing that the correct action is to coach the Product Owner to prevent the blockers from recurring.

Correct answer & explanation
✓
Coach the product owner on writing clear acceptance criteria and ensure stories are refined before sprint planning
The Scrum Master's primary responsibility is to ensure the Scrum framework is followed and to coach the team and Product Owner in effective practices. Unclear acceptance criteria are a symptom of insufficient backlog refinement, which the Product Owner owns. By coaching the Product Owner on writing clear acceptance criteria and ensuring stories are refined before sprint planning, the Scrum Master addresses the root cause of the blockers, enabling the team to deliver committed work consistently.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduce the team's velocity for the next sprint to match their actual performance
Why it's wrong here
Adjusting velocity is a result, not a solution; the root cause should be addressed.
- ✗
Increase the sprint length to give the team more time to complete work
Why it's wrong here
Changing sprint length is a process change that does not address the root cause of unclear criteria.
- ✓
Coach the product owner on writing clear acceptance criteria and ensure stories are refined before sprint planning
Why this is correct
Addressing the root cause will help the team make realistic commitments and reduce blockers.
- ✗
Remove the blockers during the standup by clarifying the acceptance criteria yourself
Why it's wrong here
While removing blockers is good, the scrum master should empower the product owner to do this consistently.

Same concept, more angles
2 more ways this is tested on PMP
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. In a Scrum project, the development team consistently fails to complete all committed stories in each sprint. The daily stand-up meetings are running long and often devolve into problem-solving sessions. As the Scrum Master, what should you do?
easy- ✓ A.Coach the team to keep the stand-up focused and time-boxed, and facilitate separate sessions for detailed discussions
- B.Add more stories to the sprint backlog to increase velocity
- C.Cancel the daily stand-up and replace it with email updates
- D.Allow the stand-up to run longer to ensure issues are resolved
Why A: The Scrum Master's role is to enforce the time-boxed nature of the daily stand-up (15 minutes) and prevent it from becoming a problem-solving session, which violates the Scrum Guide. By coaching the team to keep the stand-up focused on the three key questions (what was done, what will be done, and impediments) and facilitating separate sessions for detailed discussions, the Scrum Master addresses the root cause of the long meetings and helps the team improve sprint commitment completion. This aligns with the 'Process — Managing Technical Aspects' domain, as it involves optimizing team workflow and meeting efficiency.
Variation 2. During a sprint retrospective, a team member complains that the daily standups are too long and unproductive. Several others agree. What is the BEST action for the Scrum Master to take?
medium- A.Enforce a strict 15-minute timebox for future standups
- B.Cancel the daily standups and replace them with written status reports
- C.Move the standup to a later time when team members are more focused
- ✓ D.Ask the team to propose improvements to the standup format and agree on changes
Why D: The retrospective is the appropriate place to discuss process improvements. The Scrum Master should facilitate a discussion to modify the standup format based on the team's feedback.
