Relative Mass Valuation

Correct Answer: They should revisit their estimation model, identify the inconsistencies and modify the model as necessary.

In such scenarios where a Scrum Team finds their Relative Mass Valuation model producing inconsistent results, the team should revisit their estimation model, identify inconsistencies and modify the model as they see fit. The steps will consist of the identification of inconsistencies, evaluation of reasons behind them, making necessary changes in the model and reapplying the modified model The option of continuing to use the current model as it is doesn't hold as changes can lead to more inconsistencies. There's already evidence of inconsistency and without addressing this, the problem will not self-correct. The thought of ignoring the inconsistencies as they will balance out in the long run is incorrect as well. Waiting for inconsistencies to get resolved on their own might lead to further project uncertainties, complications and unpredictability. Similarly, the option suggesting the usage of a different valuation technique to confirm existing results does not address the core issue of inconsistency in the current model. It might validate or disprove the existing results, but it does not solve the problem within the existing model. Use of a different model can't correct the problems with the existing model.

Correct Answer: They should break down the high-value features into smaller tasks and reassess their approach.

The best approach when high-value features are taking longer than expected is to break these features down into smaller tasks and reassess their approach. This approach allows for more manageable and realistic milestones, which can help the team to meet deadlines more effectively. The other options are not ideal. Focusing on completing low-value features might meet deadlines but won’t deliver the maximum value to the customer. Pushing the deadlines is not a good practice either, because it might lead to a slippery slope of constantly postponed goals and decreased team credibility. Finally, it is not sustainable or healthy for the team to work overtime to complete the high-value features on time as it can lead to burnout and decreased productivity in the long run.

Correct Answer: The Scrum Master should facilitate the team in finding a balance by suggesting shorter, more focused estimation sessions to ensure time is also dedicated to development activities.

The correct answer emphasizes the Scrum Master’s role in coaching the team towards finding a balance that respects the team's autonomy and existing practices while addressing the specific issue of excessive time spent on estimations. It recognizes the value of the team's chosen method (relative mass valuation) and suggests optimizing rather than replacing or drastically changing the current process. The wrong answers either suggest a direct interference with the team's autonomy, introduce unnecessary complexity, or fail to directly address the issue of time management in the estimation process.
