Velocity Tracking

Correct Answer: Discuss realistic expectations and the variables that have changed since the last sprint.

As a ScrumMaster, the main responsibility is to ensure there is an environment where the team can work most effectively. The sudden increase in velocity from 20 to 30 could potentially be a sign that the team is overestimating their capabilities or there may be an external pressure pushing them to increase their workload, which can lead to burnout. The best course of action is to have a discussion with the team about realistic expectations and what has changed since the last sprint that makes them believe a 50% increase in velocity is achievable ("Discuss realistic expectations and the variables that have changed since the last sprint."). Other actions like insisting on maintaining the past velocity, suggesting working longer hours, or adjusting project requirements to match the projected velocity might lead to misaligned expectations, overworking, or invalidating the team's estimates respectively. All these actions can introduce unnecessary stress and conflict within the team, hence are not advisable in an agile setting.

Correct Answer: Explain the circumstances and reassure stakeholders that velocity is a guide, not a fixed measure.

The best answer is to 'Explain the circumstances and reassure stakeholders that velocity is a guide, not a fixed measure.' As a Scrum Master, transparency and communication are key, it's important to inform stakeholders of changes that impact the project and provide reassurances about how these changes are being managed. Velocity in a Scrum team is a guide indicating the team's capacity, it is not a constant metric and can vary according to many factors, like a team member being pulled to another project. The other answers are incorrect because they either involve providing false assurances or unrealistic expectations ('Assure stakeholders the velocity will be back up in the next sprint, even if you're not sure it's achievable.'), deceit ('Ignore the reduction in velocity and convince stakeholders all is running smoothly.'), or a lack of consideration for the team's work-life balance ('Ask the team to work extra hours to regain the lost velocity.'). These approaches do not align with the Agile values of openness, honesty, and sustainable development.

Correct Answer: Evaluate and adjust the team's story point estimation process and ensure the team understands the velocity concept.

The best solution to fluctuating velocity problems in a Scrum team is to evaluate and adjust the team's story point estimation process and ensure the team understands the velocity concept. Velocity is a measure of how much work the team can complete in a given time frame, so it's essential that everyone has a clear understanding of this concept. Evaluating and adjusting the estimation process could help ensure that the estimates are more accurate, and this in turn would help stabilize the team's velocity. The other options suggested are not the best solutions: Averaging the velocities and setting this as the team's target velocity (second option) does not address the root problem which is unstable velocity. Asking the team to work harder to deliver more story points (third option) does not necessarily improve the accuracy of the team's estimates or their understanding of velocity. Assigning more tasks to the most productive team members (fourth option) could lead to imbalances in the team which could result in other issues.
