Burn Down Chart:
Burn down chart is a graphical illustration of the remaining work to do versus time. The quantity of labor remaining is shown on the vertical axis and time is pictured on the horizontal axis.
The chart shows the entire effort against the amount of work we tend to deliver every iteration. These charts are very simple to understand.
In the burndown chart X- axis is used to represent the project timeline and y- axis represents the remaining work in the project.
There are two types of Burn down charts:
- Sprint burn down chart
- Product burn down chart
Product burndown charts provides a complete read of the project. The chart shows how many product goals the team has met and the remaining which must be done. The sprint number is pictured on the horizontal axis and the story points is pictured on vertical axis.
