The Sprint Backlog is a fundamental tool in Agile Scrum methodology, essential for Certified Scrum Developers (CSD) to fully understand. It is a subset of the product backlog, encapsulating specific tasks to be executed during a sprint.
A Sprint Backlog serves as an instrument for team members to inspect their progress during the course of a sprint and only the development team can change the Sprint Backlog during the Sprint. It details how the team plans to convert the product backlog items into a deliverable increment of potentially implementable product functionality.
Let’s dig deeper into how best to practice utilizing a sprint backlog.
Understanding of Sprint Backlog
The development team typically takes on the responsibility of creating the Sprint Backlog during the Sprint Planning Meeting. They identify tasks required to complete the selected product backlog items. The team then communicates what can feasibly be delivered in the upcoming sprint, given the team’s ongoing progress and its capacity.
The Sprint Backlog is a living document. During the sprint, as tasks are completed, new tasks identified, or as estimates change, the team updates the Sprint Backlog accordingly. It provides a real-time picture of the work that the team plans to accomplish during the Sprint.
Best Practices for Utilizing the Sprint Backlog
- Prioritization: The team should prioritize tasks in the Sprint Backlog based on the priorities of the Product Backlog items to which the tasks pertain.
- Estimation: The team should estimate the effort required to complete each task on the Sprint Backlog. Using a method like Story Points or T-shirt sizes can help provide relative estimates.
- Discussion: The entire team should understand each Sprint Backlog item. This means discussing it thoroughly during its creation.
- Visible and Transparent: Keeping the sprint backlog in a visible, readily accessible place allows the team to track their progress. Tools like physical boards, JIRA, or Trello can help with this.
- Flexibility: The Sprint Backlog is not set in stone. As new information arises, the team should tweak things accordingly while ensuring they are not jeopardizing the Sprint Goal.
Example of Sprint Backlog Utilization
Consider a software development project to build a new mobile app. The product owner prepares the product backlog items, prioritizing them based on their importance.
Let’s say one of the high-priority items is “User Registration”. The development team might break this down into smaller tasks such as:
- Design User Registration Interface
- Develop backend API for User Registration
- Write unit tests for User Registration
- Deploy User Registration to stg environment for testing
These tasks went into the Sprint Backlog during the Sprint Planning Meeting. As and when tasks are completed, they are marked as done. If during the sprint, the team finds out that UI design is taking more time than estimated, they discuss with the Product Owner regarding its complexity and reprioritize or reschedule the remaining tasks, updating the Sprint Backlog.
In conclusion, the Sprint Backlog is a valuable tool enabling the Scrum team to self-organize and make changes quickly. The Sprint Backlog is the team’s plan and the members adjust it collaboratively throughout the Sprint.
In essence, becoming proficient in utilizing a sprint backlog requires understanding its purpose, implementing it strategically, and maintaining relevancy by updating it regularly. Mastery in these areas offers a critical skill set for anyone preparing for the Certified Scrum Developers (CSD) exam.
Practice Test

- c) Development Team
Answer: c) Development Team.
Explanation: Only the Development Team can change the Sprint Backlog once the Sprint has started because they are the ones doing the work and understanding the complexities and challenges.
Single select: What is the primary purpose of a Sprint Backlog?
- a) To track what the Product Owner wants
- b) To track what needs to be done in the current Sprint
- c) To document the work done in a completed Sprint
Answer: b) To track what needs to be done in the current Sprint.
Explanation: The Sprint Backlog is a set of Product Backlog items selected for the Sprint, plus a plan for delivering the product increment and realizing the Sprint Goal.
True or False: The Sprint Backlog only includes user stories.
- True
- False
Answer: False.
Explanation: The Sprint Backlog is more encompassing and includes user stories, tasks associated with those stories, and any other items required to achieve the Sprint Goals.
Multiple select: What can be included in a Sprint Backlog?
- a) User stories
- b) Tasks
- c) Designs or other resources
- d) Bug fixes
Answer: a) User stories, b) Tasks, c) Designs or other resources, d) Bug fixes.
Explanation: The Sprint Backlog can include any items necessary to achieve the goals of the Sprint. This can include user stories, associated tasks, necessary resources and materials, and bug fixes.
Single Select: Who is responsible for tracking the work done and updating the Sprint Backlog?
- a) Scrum Master
- b) Product Owner
- c) Development Team
Answer: c) Development Team
Explanation: The Development Team is responsible for updating the Sprint Backlog as they are the ones who are completing the tasks and they understand the work in detail.
True or False: The Sprint Backlog should be understood as a highly flexible and negotiable artifact within Scrum.
- True
- False
Answer: True.
Explanation: The Sprint Backlog is flexible, and the Development Team can re-negotiate the scope of the Sprint Backlog with the Product Owner as more is learned.
Single Select: Who owns the Sprint Backlog?
- a) Scrum Master
- b) Product Owner
- c) Development Team
Answer: c) Development Team
Explanation: The ownership of the Sprint Backlog lies with the Development Team as they are the ones doing the work and understanding how to get it done.
