What role does the Scrum Master play in regard to the Sprint Review time box?

The correct answer highlights that the Scrum Master's role is to ensure that the time box for the Sprint Review is respected and adhered to. Scrum emphasizes the importance of time-boxing as a way to enhance focus and efficiency during events. Therefore, the Scrum Master plays a crucial role in managing the time during the Sprint Review, ensuring that it starts and ends at the designated times.

This is important for maintaining a structured and productive review process, where discussions can occur efficiently within the allocated time. Adhering to the time box helps to maintain the rhythm of the Scrum events and encourages teams to prepare for meetings effectively. By enforcing time limits, the Scrum Master supports the team's ability to present their work succinctly and allows adequate time for feedback and discussion, aligning with the overall principles of Scrum.

Other options suggest roles that may not align with the fundamental duties of the Scrum Master. For example, facilitating discussion until the team finishes could lead to meetings extending beyond the intended time, which is not in line with the purpose of timeboxing. Similarly, deciding when to end the meeting or managing stakeholder expectations about timing does not align with the core role of the Scrum Master, as these aspects should ideally be collaborative efforts rather than dictated by the Scrum Master alone.
