The burndown chart is a graph that visualises the project‘s progress. This curve shows the project performance. The dark blue trend line shows the actual project course: if it lies directly on the light blue line, the project runs „normal“. If it‘s in the pink area, the performance is under quota, in the light blue area it‘s better than planned.

The figure beneath the graph states, how many percents the project is performing above/under the planned time. Thus discrepancies between plan and reality can be recognised early on and countermeasures can be taken.
