Although relatively simple to construct and easy to read, burndown
charts nonetheless provide several clear advantages, even when compared
to more detail-intensive burnup charts.
Probably the most obvious benefit of the burndown chart is that it
offers a clear snapshot of project progress. It gives agile teams an
easy-to-follow visual representation of how the sprint is going, acting
as a status report, and showcasing the most important data to help
ensure that everyone involved is on the same page.
Burndown charts also assist in planning and tracking. They offer a
clear view into the progress of the project—its speed, acceleration, and
any slow patches that may arise. This not only improves reporting and
analysis, it also helps teams create more accurate plans and goals for
future projects.
Likewise, an effective burndown chart helps teams identify issues as
they occur. When the work stalls, team members can coordinate to locate
and resolve root causes before they become significant problems. This
reduces the risks involved in projects, increasing the likelihood of
achieving favorable outcomes.
Finally, burndown charts promote effective communication. By creating
a simple graphic detailing progress on the project, collaboration and
communication becomes easier.
