Burn Down Charts

Correct Answer: Team is not updating the status of tasks in real time.

In the context of a burndown chart showing a steady downward trend, yet tasks are being rolled over each day, the most likely reason is that the team is not updating the status of tasks in real time. This would mean that although work is being done, the progress is not accurately reflected on the burndown chart because updates are not being properly tracked. If the team was completing all tasks ahead of schedule, it would not result in tasks being rolled over each day, and likewise, if the tasks were too easy or too complicated for the team, it would not necessarily result in consistent roll over of tasks. It's important for task statuses to be updated regularly to ensure accurate reflection of team progress.

Correct Answer: Discuss the issue in the daily scrum, identify the problems, and try to adjust their work to meet the sprint goal.

The best approach in this situation would be to discuss the issue in the daily scrum, identify the problems, and try to adjust their work to meet the sprint goal. This is because the purpose of Scrum is to promote self-organization, inspection, and adaptation. The burn down chart is simply a tool to visualize progress, and learning from it should be part of the process, rather than being seen as a problem. The team should figure out whether tasks are bigger than estimated, or if something is blocking progress, and then collaborate on a strategy to adjust their work to meet the sprint goal. The other answers are less effective or harmful. Cancelling the current sprint and planning a new one disrupts the workflow and is not a solution to the underlying issue. Increasing the team's working hours might seem like a quick fix but can lead to burnout and reduced productivity in the long run. Ignoring the burn down chart defeats the purpose of using Scrum, which emphasizes transparency and adaptability.

Correct Answer: The team has discovered new work or requirements that were not part of the original sprint backlog, adding to the total remaining effort.

The most likely explanation for an upward trend in the burn down chart, indicating an increase in remaining effort, is that the team has discovered new work or requirements that were not part of the original sprint backlog. This additional work adds to the total remaining effort, causing the actual progress line to move upwards. The other options are less likely because: - Overestimating task completion would cause the remaining effort to appear lower, not higher. - Completing tasks ahead of schedule would result in the actual progress line moving downwards, not upwards. - Team members not updating their task status in a timely manner might cause the progress to appear slower, but it would not directly increase the total remaining effort.
