Throughput

Correct Answer: Show patience for the team to become proficient in the new language, until then focus on smaller stories.

In an Agile context like Scrum, learning and adaptation are key values. Hence, 'Showing patience for the team to become proficient in the new language, and focusing on smaller stories in the meantime' is the best suggested action based on these principles. For the explanation of why the other answers are not suitable, the reasoning is as follows: For 'Forcing the team to work in the old programming language', it is counter to the spirit of continuous improvement and adaptation that is core to Agile and Scrum. The third option mentioned, 'Demanding faster output from the team' can result in rushed and potentially low quality work, which does not line up with the principles of Scrum. The final suggestion, 'Hiring new developers who are proficient in the new language and letting go of the current team' overlooks the value of the team's existing knowledge and domain expertise, and would likely also create a poor team culture, as Scrum emphasizes individuals and interactions over processes and tools.

Correct Answer: Analyze the impact of the legacy code on the team's velocity and collaborate with the team and Product Owner to prioritize technical debt in the product backlog.

The correct approach involves acknowledging the drag caused by the legacy code on the team's velocity and working towards a sustainable solution by prioritizing the technical debt in the backlog. This way, the team can systematically address the issue without compromising on the delivery of new features. The wrong answers, although related to development practices, either suggest creating sub-teams (which can dilute the focus and efforts of the team), altering sprint duration (which doesn't address the root problem and might lead to burnout), or enforce pair programming (which is beneficial but not a standalone solution to handling problems associated with legacy code).

Correct Answer: Arrange a cross-team workshop to understand the challenges and identify a process to smoothen the integration with minimum disruption to throughput.

The correct answer focuses on collaboration and problem-solving within and across teams to address the integration issues causing a decrease in throughput. Advocating for new tools or allocating fixed time slots may seem like solutions but do not address the root cause of the problem or involve collaborative problem-solving. Reporting the issue to higher management for intervention sidelines the empowerment and self-organization principles of Scrum teams.
