Burndown Charts

Correct Answer: The team is overestimating efforts and ending up rushing towards the deadline.

This situation suggests that the team is overestimating efforts and ending up rushing towards the deadline. This rush towards zero at the end of the Sprint often shows a tendency of the team to overcommit or poorly estimate their work, and thus having to accelerate their efforts to deliver workitems in the last moment. It can also indicate problems with how tasks are distributed or perhaps a lack of understanding of the Scrum process. This is not a sign of efficiency as the workload is imbalanced during the sprint, and processes are not constant The answers suggesting that the Scrum Master is not updating the chart regularly, members of the team worked overtime in the last two days, or the team is efficiently utilizing their time in the sprint are not necessarily correct. The Scrum Master not updating the chart regularly would lead to inaccuracies in the Burndown Chart, but wouldn't necessarily result in a rush towards zero. Team members working overtime could potentially result in a rush towards zero, however, it's not best practice and is not sustainable for long-term projects. Lastly, an efficient utilization of time would mean a balanced line in the Burndown Chart, not a rush towards the end.

Correct Answer: The team did not complete any tasks during those days.

The Burndown Chart represents the amount of work which has been completed in a given sprint. If the line on the chart seems to be horizontal for a few days, it indicates that there has not been any change in the amount of work done during those days. So, the most plausible explanation for such a situation can be that the team did not complete any tasks during those days. Let's consider the alternatives. 'The Scrum Master failed to update the chart' is incorrect because the Burndown Chart is usually updated automatically as tasks are marked as completed in the project management tool, although a manual update is possible but unlikely to be neglected. 'The team has achieved their sprint goal early' is incorrect because, if that was the case, the line would drop to the bottom, and not stay horizontal. Lastly, 'the charting tool has a technical glitch' is a possible explanation but less likely than the team failing to complete tasks, this would be clear if other aspects of the tool are working correctly.

Correct Answer: New tasks were added in the middle of the sprint, but the team managed to complete all tasks.

The best possible answer is 'New tasks were added in the middle of the sprint, but the team managed to complete all tasks.' Why? In Scrum, a Burndown Chart represents the work left to do versus time. If the chart shows a slight trend upwards but eventually ends below the ideal line, this could indicate that additional tasks were added mid-sprint, causing the work left to do to increase temporarily (upwards trend). However, the Scrum team was able to finish all tasks by the end of the sprint (ends below the ideal line). The answer 'The team did not make progress and failed to complete the tasks.' is incorrect, because the chart ends below the ideal line, indicating that all tasks were completed. The answer 'The team was overestimating task complexity at the start of the sprint.' is incorrect because an upward trend suggests more work was added, not less. Lastly, the answer 'The team is not using the Burndown Chart properly.' is incorrect since the pattern described is a possible event that can occur in Scrum projects when dealing with uncertainties and could be accurately reflected on a Burndown Chart.
