Wideband Delphi

Correct Answer: Continue with the process but take the lesser expertise into account during the discussions.

In the Scrum methodology, all team members contribute valuable insight and the Wideband Delphi estimation process is a democratic approach. It benefits from a diversity of perspectives and experiences, even if those experiences are not as substantial as initially thought. Hence, the correct process would be to 'Continue with the process but take the lesser expertise into account during the discussions'. Excluding the team member or disregarding any input from them contradicts the values of Scrum, which is based on collective knowledge sharing and decision-making. Replacing the team member in the middle of the process could disrupt team dynamics and continuity of work.

Correct Answer: Approach the participant privately to investigate if there is a misunderstanding or differing assumptions.

In a Wideband Delphi estimation process, if one participant consistently provides estimates that are far off from the rest of the team, the best approach is to discuss the matter privately with them. This approach is preferred because it encourages open communication and allows issues such as misunderstandings or differing assumptions to be addressed without creating discomfort or tension within the team. Dismissing the participant from the estimation process may not identify any potential misunderstandings that could be influencing the estimates. Ignoring the participant's outliers could lead to inaccuracies in the final estimate, especially if their input is based on valid assumptions. Publicly questioning the participant's understanding may discourage them from actively participating in future discussions, preventing any meaningful resolution to the differing estimates.

Correct Answer: Explain the importance of the meetings, allow suggestions, and make suitable modifications to make the process more efficient.

The approach of a ScrumMaster should always lean towards the improvement of established processes and not completely abandoning them or insisting on strict adherence without considering team's feedback. This makes the option - 'Explain the importance of the meetings, allow suggestions, and make suitable modifications to make the process more efficient' as the best approach in this case. The ScrumMaster would support the team by ensuring that the process serves them and not the other way around. Increasing efficiency can result in less time invested and increased team satisfaction. On the other hand, 'Skip the consensus meetings and directly collect estimates' is not advisable as it contradicts the scrum principle of team collaboration and consensus building. Similarly, 'Insist on following the process strictly without any changes' does not serve the agile belief of responding to change and eliminates opportunity for improvement. ‘Exclude those who feel it is time-consuming’ is also not a favorable approach as it goes against the principle of collective responsibility and team collaboration.
