Velocity Chart

Correct Answer: Facilitate better communication between the product owner and development team to improve the clarity of user stories.

The best reaction from a ScrumMaster to resolve the issue of fluctuating velocity due to ambiguous user stories is to facilitate better communication between the product owner and the development team. This will help in clarifying the user stories, improving their understanding and subsequently result in better estimations and steady velocity. Now let's examine the other options:- Telling the development team to estimate better despite unclear stories isn't a good solution, as estimations are highly dependent on the clarity of the user story. Unclear user stories will lead to inaccurate estimations - Asking the product owner to write clear user stories without collaborating with the development team isn't effective either. It's crucial for the team to be involved in the creation of user stories to ensure there is shared understanding - Ignoring the problem and expecting it to resolve on its own isn't a proactive or constructive approach. As the ScrumMaster, it's essential to facilitate and address any issues that may impact the effectiveness and performance of the team.

Correct Answer: The team might be taking on tasks outside the scope of the sprint impacting product development.

In Scrum, velocity is a measure of how much product backlog effort a team can handle in one sprint. If the velocity chart shows a constant velocity, it implies that the team is consistently completing their committed tasks for each sprint. However, if the overall product scope is not progressing adequately, it indicates that those tasks aren't contributing significantly towards the product development. This could be because the team might be taking on tasks outside the scope of the sprint, which deviate from the main product goals. In this case, the role of the Product Owner is incorrect. A product owner's responsibility is to ensure that the team is working on business value-oriented tasks rather than refilling the work. The premise 'The development team isn't working efficiently' is incorrect since the velocity is consistent which indicates the team is actually working efficiently on the tasks given to them. Lastly, the answer 'The Scrum Master is not managing the team well' is not necessarily the case. The Scrum Master's role is more about ensuring the team follows Agile principles and Scrum rules. The discrepancy in product scope progress can exist even when a Scrum Master is performing their responsibilities adequately.

Correct Answer: The team has been facing external problems that are hindering their progress.

The team's velocity chart showing a consistent decrease over the last three sprints may well be a result of the team facing external problems that are hindering their progress, such as technical difficulties, task dependencies or other unforeseen hindrances. This could essentially be affecting their productivity and slowing down the team's velocity despite their best efforts. The team becoming efficient would mean that they are getting better at their tasks and thus their velocity should increase, not decrease. Hence, this answer is not valid. The team being given too many easy tasks should also ideally increase the velocity, because the tasks are easier to complete. Therefore, this answer isn't logical either. Lastly, the product owner's involvement isn't directly correlated with the team's velocity. While the product owner plays a critical role in prioritizing the backlog and interacting with the team, his or her involvement won't necessarily directly impact the team's velocity to the point of causing a consistent decrease over three sprints.
