Burndown Chart Definition and Summary

When combined with a velocity estimate, burndown charts can predict if your team is likely to complete the outstanding work in the available time. A burndown chart is also a helpful tool to identify any scope creep, as items will take longer to complete than expected. It can be used to track the total work remaining in the sprint, and to project the likelihood of achieving the sprint goal. By tracking the remaining work throughout the sprint, a team can manage its progress, and respond to trends accordingly.

You can do this by gathering your estimates and comparing them against your logged time. It’s a good idea to keep your logged time in a shared space where team members can access the data throughout the project. At the end of the fifth day, each of the tasks should add up a total of 80 hours as estimated in the first step. It’s important to understand each of the pieces that make up a burndown chart so that you can effectively read and create one of your own.

For example, imagine your Agile team had 50 story points left to complete. (A story point is a unit of measurement that Scrum teams assign to tasks or stories to indicate how much effort they think will be required.) Then, a change occurred, which added 10 more SPs.

A burndown chart shows the amount of work that has been completed in a sprint and the amount of work that is remaining.

The daily progress is then captured in the table against each task. It is important to remember that the value captured for each day is the estimated effort to complete the task, not the actual effort.
