Burndown Chart
A Burndown Chart is a graphical representation of work remaining versus time in a Sprint or release, showing whether the team is on track to complete the planned work.
Explanation
A Burndown Chart plots the amount of remaining work (typically in story points or hours) on the Y-axis against time (days in the sprint) on the X-axis. An ideal trend line slopes downward from the total planned work to zero by the end of the sprint. The actual line shows the team's real progress.
If the actual line is above the ideal line, the team is behind schedule. If it is below, the team is ahead. The chart makes it immediately visible whether the team is on track and is typically updated daily. It is one of the most commonly used information radiators in agile.
Burndown Charts can be created at the sprint level (Sprint Burndown) to track daily progress within a sprint, or at the release level (Release Burndown) to track progress across multiple sprints toward a release goal. Both provide transparency and support empirical process control.
Key Points
- •Plots remaining work versus time
- •Ideal line slopes from total planned work to zero
- •Updated daily to provide real-time visibility
- •Available at sprint level and release level
Exam Tip
A burndown chart shows remaining work trending toward zero. If you see a chart trending upward, it indicates scope is being added faster than work is being completed.
