What is a Sprint Burndown Chart?
The Sprint Burndown or the Iteration Burndown chart is a powerful tool to communicate daily progress to the stakeholders. It tracks the completion of work for a given sprint or an iteration. The horizontal axis represents the days within a Sprint. The vertical axis represents the hours remaining to complete the committed work. As Mike Cohn rightly stated, the purpose of a sprint burndown chart is to show the total amount of work remaining.
The below table shows the number of hours remaining at the end of each day within a Sprint to create a sample Sprint burndown chart. The ideal remaining hours are calculated by assuming a uniform rate of task completion each day.
The Scrum Master creates a Sprint Burndown chart using such data. The below diagram depicts a sample Sprint Burndown chart with ‘Date’ represented on the horizontal axis and ‘Remaining Effort (Hours)’ represented on the vertical axis.
