What does the Sprint Burndown measure?

The Sprint Burndown chart is a visual representation of the work remaining in a Sprint, specifically focusing on the remaining effort in the Sprint Backlog over time. It tracks how much work is left to be done as the team progresses through the Sprint. This allows the Development Team and stakeholders to see how much of the planned work has been completed and how much remains, providing insights into the team's progress and the likelihood of completing the Sprint goal within the scheduled time.

By monitoring the remaining Sprint Backlog throughout the Sprint, teams can identify whether they are on track, adjust their pace if necessary, and facilitate discussions during the Daily Scrum to address any impediments. This focus on remaining work is crucial for maintaining transparency among the team and stakeholders, making it a key measurement in Scrum practices.

The other choices misinterpret the role of the Sprint Burndown. While total completed work at the Sprint’s end is important, it does not encapsulate the tracking of progress during the Sprint itself. The estimated time remaining might imply a focus on a time-based metric rather than the specific backlog items. Lastly, measuring productivity is a broader and more ambiguous metric that does not directly relate to the purpose of the Sprint Burndown in reflecting work remaining.
