Scrum Artefacts and their Application

Correct Answer: The Product Owner should regularly refine and prioritize the Product Backlog, and the team should provide feedback.

The best answer is 'The Product Owner should regularly refine and prioritize the Product Backlog, and the team should provide feedback.' This is the proper way to handle a growing product backlog in a Scrum environment. As the Product Owner, it's their responsibility to manage the backlog, including expansion and prioritization. The team's input is also crucial as they are involved in implementing these items. The other answers either suggest unproductive solutions (like working longer hours or stopping the addition of new items, which may compromise project goals) or give inappropriate responsibilities to the Scrum Master (who doesn't have the authority to delete backlog items indiscriminately).

Correct Answer: The team involves the Product Owner to pull more items into the Sprint from the Product Backlog.

In the Scrum methodology, when a team completes all the items in the Sprint Backlog before the Sprint time frame is over, they should involve the Product Owner to pull more items into the Sprint from the Product Backlog. This maintains the collaborative and adaptive nature of Scrum, optimizing the team's efficiency and making best use of the remaining time from the Sprint. The team should not consider the Sprint finished and start a new one immediately as it opposes the time-boxed nature of a Sprint and could lead to improper planning and analysis. Also, taking a break until next Sprint or working on anything without consulting the Product Owner isn't suggested as it wastes the available time and could lead to the team working on not so valuable items.

Correct Answer: The Scrum Master should coach the team member to improve their estimates, and the team should adapt by planning more realistically in future Sprints.

In a Scrum team, when a team member is consistently unable to finish their tasks within the Sprint time frame, the team should not take drastic measures such as excluding the member from future Sprint planning meetings. Neither should they ask for extensions to the current Sprint. The focus should instead be on understanding why this is happening and improving the estimation and planning process. The Scrum Master should coach the team member to improve their estimates. This is significant as Scrum values self-management and continuous improvement. Asking for extension or assigning fewer tasks might not solve the root issue and does not help in the overall growth and efficiency of the team. Adapting and planning more realistically in future Sprints based on past Sprint experiences encourages learning and improves overall team performance.
