Collaborative Solution

Correct Answer: Ask the team member to present their case at the upcoming sprint planning session, encourage open discussion and collaboratively decide based on potential benefits and cost impact.

The best answer is to 'Ask the team member to present their case at the upcoming sprint planning session, encourage open discussion and collaboratively decide based on potential benefits and cost impact.' This approach aligns with the principles of Agile and Scrum, which value communication, collaboration, and adaptation. The Scrum Master's role is to facilitate this process and ensuring all perspectives are considered before making a decision. 'Reject the idea outright due to potential increased costs', 'Ignore the suggestion and follow the original plan' and 'Implement the change without any discussion' are all contrary to Agile principles. They discourage collaboration and open discussion, and do not allow the team to adapt to potential improvements.

Correct Answer: Facilitate a workshop with the team and stakeholders to brainstorm and vote on the best solution.

The best approach during a sprint review when the team faces a difficult situation like implementing a new feature would be to facilitate a workshop with the team and stakeholders to brainstorm and vote on the best solution. This is following the principles of Agile methodology, where collaboration, communication, and coming up with solutions as a team is the key focus. Assigning someone to devise a solution on their own would negate the collective wisdom of the team and stakeholders, and might not serve the best interests of the project or the sprint. Taking control and prescribing a solution also goes against Agile principles, wherein a single person does not dictate the course of action, but it's a collective decision. Avoiding implementation of the new feature just to maintain the sprint velocity is also counterproductive as it prevents the team from adapting to changes and improvements, which is one of the cornerstones of Agile methodology.

Correct Answer: Seeking external expertise through consultants or another team within the organization, while ensuring the team's involvement in understanding the solution

The best course of action when faced with a technical issue that none of the current team members have the skills to tackle, is 'Seeking external expertise through consultants or another team within the organization, while ensuring the team's involvement in understanding the solution'. This approach not only addresses and solves the current issue but also equips the team with new knowledge and skills to tackle similar problems in the future, thereby enhancing their productivity and efficiency. On the other hand, 'Ignoring the issue and hoping it resolves itself' isn't a productive method as it doesn't resolve the problem at hand and can potentially delay the project further. 'Asking a team member to learn the skills overnight' may put undue pressure on the team member and there is no guarantee that the team member can learn and apply the new skills efficiently in such a short time. 'Hiring a new team member to solve this issue only' is neither time-efficient nor cost-effective, as hiring processes can be lengthy and training new members can slow the progress of the current sprint.
