Understanding Burndown Charts in Scrum
Burndown charts can be a useful tool in Scrum for visualizing the progress of a Scrum Team. They help track the amount of work remaining and provide insights into the team’s progress over time. However, it is important to note that burndown charts are not mandatory in Scrum; they are an optional practice that teams may choose to use.
Exam Question
If burndown charts are used to visualize progress, what do they track?
(choose the best answer)
- A. Accumulated business value delivered to the customer.
- B. Individual worker productivity.
- C. Accumulated cost.
- D. Work remaining across time.
Correct Answer
D. Work remaining across time
Explanation
D. Work remaining across time
Work Remaining: The primary purpose of a burndown chart is to track the amount of work remaining in a Sprint or a project. This is typically represented on the vertical axis, while time is shown on the horizontal axis.
Progress Visualization: By visualizing the work remaining over time, the Scrum Team can see whether they are on track to complete the work by the end of the Sprint or release. It helps in identifying trends and making necessary adjustments.
Optional Tool: While burndown charts can assist the Scrum Team in managing their progress and adapting their efforts to meet the Sprint Goal, they are not a required practice in Scrum.
Incorrect Options
- A. Accumulated business value delivered to the customer: While delivering business value is crucial, the burndown chart specifically tracks work remaining, not the value delivered.
- B. Individual worker productivity: The focus of a burndown chart is on the collective work remaining for the team, not individual productivity.
- C. Accumulated cost: Burndown charts do not track costs. They are used to monitor progress in terms of work remaining over time.
Responsibilities in Scrum
- Product Owner: While the Product Owner is responsible for maximizing the value of the product, they do not directly use burndown charts to track progress. They use the information from these charts to make informed decisions about the Product Backlog.
- Scrum Master: The Scrum Master helps the team use the burndown chart effectively to visualize progress and identify any impediments that may need to be addressed.
- Developers: The Developers use the burndown chart to track their progress towards completing the Sprint Goal and to make any necessary adjustments to their work plan.
