Enforcing Scrum Rules

Correct Answer: Coach the team in refining their estimations to fully utilize the Sprints.

The most suitable action for the ScrumMaster when the team consistently finishes their tasks before the end of the Sprint would be to coach the team in refining their estimations to fully utilize the Sprints. This means improving planning and estimation skills so the team can better predict how much work they can get done during a sprint, and thus maximize their productivity. On the other hand, scheduling additional items for the team to work on disrupts the prioritization of the backlog and breaks the time-boxing principle of Scrum. Ending the Sprint early and starting a new one immediately would require additional overhead of Sprint planning, review, and retrospective, which could create disruptions. While free time can foster creativity, it's not really addressing the issue at hand, which is the team underestimating the amount of work they can do in a sprint.

Correct Answer: Remind the team that only 'done' items can be presented during the Sprint Review.

The role of a ScrumMaster includes ensuring that the Scrum Team adheres to Scrum theory, practices, and rules. According to Scrum Guide, only 'Done' items can be presented during the Sprint Review. This means that all the development work, testing, and documentation for the backlog item should be completed. If the team shows unfinished backlog items claiming they will finish them soon, it indicates a violation of this rule. Hence, the ScrumMaster should remind the team that only 'done' items can be presented during the Sprint Review. Let's review the other answers. 'Allow the team to demonstrate the unfinished items, their progress must be recognized.': This answer is incorrect as it goes against the Scrum Guide, which states that only 'done' items should be presented. This could also raise a false sense of progress. 'Cancel the Sprint Review since they violated the Scrum rule.': This is too drastic and isn't generally recommended, unless the whole Sprint failed. 'Take note and discuss this during the Sprint Retrospective.': Although this seems like a proactive step towards inspection and adaptation, the violation should be addressed immediately in Scrum. So this answer doesn't solve the present problem.

Correct Answer: Remind the team of the purpose and timebox of the Daily Scrum, and encourage them to have detailed discussions outside the meeting

The best approach is to remind the team of the purpose and timebox of the Daily Scrum, and encourage them to have detailed technical discussions outside the meeting. The Daily Scrum is meant to be a brief, time-boxed event where each team member shares their progress, plans, and impediments. It is not intended for in-depth technical discussions, which can be held separately. Allowing the meeting to consistently exceed the 15-minute timebox defeats its purpose and can lead to ineffective communication. Canceling the Daily Scrum or reducing its frequency goes against the Scrum framework and may hinder the team's ability to synchronize and plan their daily work.
