What Is a Burn Down Chart?

Burn down chart (English: burn down chart ) is a work chart used to represent the remaining workload. It consists of the horizontal axis (X) and vertical axis (Y). The horizontal axis represents time and the vertical axis represents workload. This kind of chart can intuitively predict when the work will be completed. It is often used in agile software development in software development, and can also be used for other types of workflow monitoring.

If the actual work line is higher than the ideal work line, it means that the remaining work is more than originally predicted, and the project is behind schedule.

If the actual work line is lower than the ideal work line, it means that the remaining work is less than originally predicted and the project is completed ahead of schedule.

One issue that may be noticed in burndown charts is whether the actual working line is higher or lower than the ideal working line depends on the accuracy of the original time estimate. This means that if the team constantly overestimates time requirements, progress will always occur ahead of time. If they often underestimate time requirements, they will always be behind schedule. Correct this problem by including the efficiency factor in the burn chart. After the first iteration of the project, the efficiency factor can be recalculated to allow a more accurate estimate during the next iteration. Some templates automatically calculate efficiency as the project progresses. This can be used to identify areas / stages where there are always inaccurate estimates.
