A burndown chart is a simple way of measuring a team's progress during a sprint by comparing the working days in the sprint to the total number of story points to which the team committed.
A story is considered complete when it does not have any remaining story points and after it has been accepted by a product owner. A sprint can be considered complete when the total story points to which the team committed reaches zero or when the time allotted to the sprint (1-4 weeks) runs out. Ideally, this occurs before the last working day of the sprint. Stories not completed in time are not accepted by the product owner and are moved to a subsequent sprint. Working days in a sprint are defined by the working days in your organization's company calendar.
Serena Agile includes an out-of-the-box sprint burndown chart as part of the Tracking module. The sprint burndown chart is used to view the current status of the sprint. The list of stories, sorted by work state will appear in the related backlog pane. The burndown chart shows the backlog from which the burndown chart is based as part of the release, sprint, and task burndown chart views.
