The Burn Down Chart
A burn-down chart is a graphical representation that shows the progress made during the development cycle.
The Burn Down Chart can be used to show outstanding work for a release or for a sprint and in both cases, the chart represents the amount of work remaining for the completion of the release or sprint versus time.
How the Burn Down Chart works?
The vertical axis (Y-axis) of the chart presents the work remaining to complete the release or sprint while the horizontal axis (X-axis) represents the time.
The chart typically presents 2 lines going from the top left section of the chart towards the bottom right. While the first line presents an estimate of work delivered over time, the second line shows the actual values. As such, the Burn Down Chart is useful for predicting when the work scheduled for the current release or sprint will be completed.
