The Concept of Sprint 0 in Scrum
In Scrum, the concept of “Sprint 0” is often debated. However, it is essential to understand what Scrum officially prescribes regarding the start of Sprints and the roles and responsibilities within the framework.
Exam Question
What is the accountability of the Product Owner during Sprint 0? (choose the best answer)
- A. Create the overall release plan to ensure that organizational goals are met.
- B. Make sure enough Product Backlog items are refined to fill the first 3 Sprints.
- C. Gathering, eliciting, and analyzing the requirements to build the Product Backlog.
- D. Determine the composition of the Scrum Team to meet the release plan.
- E. There is no such thing as Sprint 0.
Correct Answer
E. There is no such thing as Sprint 0.
Explanation
Why E is Correct
E. There is no such thing as Sprint 0:
In Scrum, the concept of “Sprint 0” does not exist. Scrum emphasizes a continuous flow of work starting with the first Sprint, where a usable Increment is expected. The idea of a preparatory phase before the actual Sprints contradicts the principles of Scrum, which advocate for delivering a potentially releasable product increment at the end of each Sprint.
Why A, B, C, and D are Incorrect
A. Create the overall release plan to ensure that organizational goals are met:
While release planning is important, it is not a task designated for a “Sprint 0” but rather an ongoing activity managed by the Product Owner.
B. Make sure enough Product Backlog items are refined to fill the first 3 Sprints:
Product Backlog refinement is an ongoing process and not something confined to a preparatory phase.
C. Gathering, eliciting, and analyzing the requirements to build the Product Backlog:
Building and refining the Product Backlog is a continuous process that happens throughout the project lifecycle.
D. Determine the composition of the Scrum Team to meet the release plan:
The composition of the Scrum Team is typically determined at the start of the project and adjusted as needed, not during a preparatory phase.
Key Points
- Continuous Delivery: Scrum emphasizes starting with the first Sprint and delivering value incrementally.
- No Preparatory Phase: The notion of “Sprint 0” contradicts the Scrum framework, which advocates for immediate and continuous delivery.
- Ongoing Activities: Activities such as backlog refinement, requirement gathering, and release planning are ongoing and not confined to a specific phase.
Roles and Responsibilities in Scrum
- Product Owner: Responsible for managing the Product Backlog, ensuring it is refined and ordered, and maximizing the value of the product.
- Scrum Master: Facilitates Scrum events and ensures the team adheres to Scrum principles.
- Developers: Work collaboratively to deliver potentially releasable increments every Sprint.
Relevance to the PSM I Exam
Understanding that there is no “Sprint 0” in Scrum is crucial for the PSM I exam. This knowledge helps candidates appreciate the continuous and iterative nature of Scrum and the importance of starting with delivering value from the first Sprint.
Conclusion
There is no such thing as “Sprint 0” in Scrum. Scrum advocates for starting with the first Sprint and continuously delivering potentially releasable increments. Understanding this principle is essential for adhering to the Scrum framework and ensuring effective Scrum implementation.
