Final answer:
The time-box for a Sprint Review in a 2-week Sprint is typically up to 4 hours. A precise stopwatch would be helpful for accurately timing sprint races with close finishes. Tracking sleep over two weeks can reveal its impact on energy and performance levels.
Step-by-step explanation:
The time-box for a Sprint Review in Scrum, assuming a 2-week Sprint, is typically a maximum of 4 hours. This time frame is a guideline and can be adjusted based on the size of the team and the complexity of the work done in the Sprint. However, for a 2-week Sprint, this duration is usually sufficient to ensure that the team can discuss the completed work, and the sprint backlog, and demonstrate the outcomes to stakeholders. It's also an opportunity to receive feedback to help plan the next steps for the upcoming sprint.
As for the school's last track meet scenario where the difference between the first and second-place sprinters was only 0.03 seconds, having a new, precise stopwatch would certainly help time the sprint team as it would provide accurate measurements for such close races. The precision would assist coaches in making informed decisions based on the athlete's performance.
Regarding the mini activity on sleep, tracking sleep over two weeks could reveal significant insights into how much sleep an individual needs to maintain optimal physical and mental energy levels. It's a personal experiment to explore the effects of sleep on daily performance.
