Sprint Backlog

Correct Answer: Organize a refinement session to go over the AC with the Product Owner and team to ensure a shared understanding.

The best way to address the issue of unclear Acceptance Criteria (AC) is by organizing a refinement session with both the Product Owner and the team, ensuring that everyone has a shared understanding of what is expected. Using the definition of done (DoD) as a substitute for AC does not address the problem because both serve different purposes. Escalating the issue to higher management is not in line with Scrum principles, which advocate for self-organizing teams. While splitting items into smaller tasks may help in some cases, it does not directly ensure that the AC is understood by the team; rather, it could lead to further confusion if not managed properly.

Correct Answer: Introduce a visual management tool such as a task board or a burndown chart.

The best solution as a Scrum Master when team members can't observe the status of tasks in the sprint backlog is to introduce a visual organization tool such as a task board or a burndown chart. A task board clearly demonstrates the status of each task in a sprint making it simpler and easier for everybody to see the progression of work. A burndown chart, on the other hand, graphically represents the actual and projected rate of work complete over time. Both these tools are effective ways to visualize progress and increase transparency. The remaining answers are not ideal solutions. Requesting the Product Owner to monitor the team's progress more closely does not address the core issue which is lack of visibility into the status of tasks. Suggesting the team members to work overtime won't necessarily aid in making the status of the tasks clearer, it might only overwork the team. Taking over the responsibility of Sprint backlog isn't Scrum Master's role and it doesn't solve the issue of visibility to the team.

Correct Answer: Encourage the Development Team to self-organize and find a solution to the complexities, ensuring transparency and preserving the Sprint scope as much as possible.

Scrum encourages teams to be self-organizing, to communicate among themselves, and to collectively tackle issues that arise during a Sprint. Extending the Sprint, reducing the definition of done, or unnecessarily escalating the problem contradicts Scrum principles of time-boxing, maintaining quality, and team autonomy. The correct answer emphasizes collaboration, transparency, and problem-solving within the team. Breaking down tasks or renegotiating the Sprint scope with the Product Owner could be considered if the team deems it necessary, but those actions should preserve the integrity of Scrum principles.
