Burn Down Chart: To observe the progress of project development Burn Down Chart is used. It illustrates the
remaining work in respect of time. The horizontal axis of Burn Down Chart displays time; the vertical axis shows the
amount of work (story point, work hour, team days) remaining.
A sprint Burn Down Chart exhibits daily progress. The remaining work should reduce at every day of a sprint, so the
ideal scenario for sprint Burn Down Chart would look like downward straight line as Fig. 3. However, in real time some
deviations from actual straight line exist due to wrong estimation, programmer inefficiency or addition of new
requirements by the product owner
