Burndown Chart Example
I can describe a simple example of a burndown chart to help you understand how it typically looks and what information it conveys. In this example, we’ll consider a Scrum project with a two-week sprint.
Let’s assume the team has estimated work in story points, and they have a total of 40 story points planned for the sprint. The burndown chart might look like this:
- Day 0 (Start of Sprint):
- Total Story Points: 40
- Completed Story Points: 0
- Remaining Story Points: 40
- Ideal Burndown Line: A diagonal line from the top left (40) to the bottom right (0) over the 10 days.
- Day 3:
- Completed Story Points: 10
- Remaining Story Points: 30
- Day 5:
- Completed Story Points: 20
- Remaining Story Points: 20
- Day 8:
- Completed Story Points: 30
- Remaining Story Points: 10
- Day 10 (End of Sprint):
- Completed Story Points: 40
- Remaining Story Points: 0
- Ideal Burndown Line: Reached the bottom right corner
The burndown chart visually represents the progress of the team over the sprint. The x-axis typically represents time (in this case, the days of the sprint), and the y-axis represents the amount of work (in this case, story points). The actual burndown line shows the actual work completed each day, and the ideal burndown line represents the ideal progress if all work was completed evenly throughout the sprint.
In a healthy sprint, the actual burndown line should be close to or following the ideal burndown line, indicating that the team is on track. Deviations might suggest challenges that need attention, such as scope changes, impediments, or underestimated work. Burndown charts are powerful tools for teams to visualize their progress and make informed decisions during the sprint.
Sample Burndown Chart
I can’t provide visual images, but I can describe a sample burndown chart for you. Burndown charts are typically created using tools like Jira, Excel, or other project management software. Here’s a textual representation of what a sample burndown chart might look like:
In this example:
- Day: Represents the day of the sprint.
- Ideal Burndown: Represents the ideal progress, assuming the team completes a consistent amount of work each day. It decreases linearly from the total estimated work at the beginning of the sprint (40 in this case) to 0 by the end of the sprint.
- Actual Burndown: Represents the actual progress made by the team each day. The numbers indicate the cumulative work completed. For example, on Day 3, the team has completed 5 story points, and on Day 5, they have completed a total of 24 story points.
The chart visually shows how the team’s actual progress compares to the ideal progress over the course of the sprint. A well-functioning team will have their actual burndown line tracking close to the ideal burndown line, while deviations might indicate issues that need attention.
