Multi team Product Backlog Refinement

Correct Answer: Facilitate a discussion between both teams to come to a consensus while ensuring that the solution aligns with the product's value and mission.

The Scrum Master's role is to facilitate the process and create an environment where teams can self-organize and make their own decisions. This means, instead of choosing a solution himself/herself, as suggested in one of the wrong answers, the Scrum Master should facilitate a discussion between the two teams to come to a consensus. This approach ensures that the final decision aligns with the product's value and mission. Allowing each team to implement their own solution, as suggested in another wrong answer, will lead to inefficiency and could conflict the solution's alignment with the product's aim. Lastly, completely leaving the teams to resolve it on their own, without providing the necessary facilitation, as suggested in the third wrong answer, can lead to prolonged disputes and ultimately delay the project.

Correct Answer: Facilitate a collaborative discussion encouraging teams to find common ground, and remind the teams of the shared goal.

The best approach as a Scrum Master when conflicts arise over differing technical views is to 'Facilitate a collaborative discussion encouraging teams to find common ground, and remind the teams of the shared goal.' This is because the role of a Scrum Master involves acting as a facilitator in helping the teams to solve their problems by themselves. This approach promotes a sense of mutual respect and understanding among the team members, and it also helps to ensure that the best technical solution is chosen which is in line with the product goals. The Scrum Master is not expected to impose his or her own views ('Choose the technical view which appears the most viable to you.'), or let the teams resolve their conflicts entirely without intervention ('Let the teams resolve their differences without your intervention, considering the self-organizing nature of scrum teams.') due to the risk of protracted conflicts that can negatively affect the project progress. Also, escalating the issue to higher authority ('Escalate the issue to higher authority for resolution.') should be the last resort only if the issue can't be resolved within the team, as it breaks the principles of team self-organization and responsibility.

Correct Answer: Use it as an opportunity to reassess and adapt the current forecast items. Get the entire team and owners involved to discuss and re-prioritize items.

The most appropriate way to deal with substantial feedback for old product backlog items that may influence current ones in the forecast is to use it as an opportunity to reassess and adapt the present forecast items. The entire team, along with the product owners, should be involved in this process to discuss how the insights from the old backlog item feedback may affect and possibly improve the priority and approach to the current forecast items. This approach is in line with the spirit of Scrum, which promotes adaptation and continuous improvement based on feedback. The other answers are not right because: 'Ignore the old feedback and continue working on current items as per the initial forecast.' - This is not the correct approach as Scrum calls for adapting based on feedback, which this approach does not support. 'Discuss the old feedback only with the product owner.' - While the product owner may be able to provide valuable input on the relevance of the old feedback, the entire team should be involved in these discussions to promote transparency and collective ownership. 'Delay all current work and focus on the old feedback items only.' - This approach does not align with Scrum practices as it lacks the consideration of prioritization based on the value the feedback can add to the current forecast items.
