Coordinating Multiple Scrum Teams
When multiple Scrum Teams work on the same product simultaneously, coordination and integration are crucial to ensure that the teams deliver a single, coherent Increment at the end of each Sprint.
Exam Question
Which statements are true when multiple Scrum Teams work on a software product at the same time?
(choose the best two answers)
A. Code is merged at the Scrum of Scrums.
B. The Scrum Teams must integrate their work before the end of the Sprint.
C. Each Scrum Team should have a different Product Owner.
D. The Scrum Teams coordinate their work to deliver a single Increment.
E. All Scrum Teams work in their own version control branch.
Correct Answers
B. The Scrum Teams must integrate their work before the end of the Sprint.
D. The Scrum Teams coordinate their work to deliver a single Increment.
Explanation
Correct Answers
B. The Scrum Teams must integrate their work before the end of the Sprint:
When multiple Scrum Teams are working on the same product, it is essential that their work is integrated before the Sprint ends. This integration ensures that the Increment delivered at the end of the Sprint is cohesive, functional, and potentially shippable. Failure to integrate could result in incomplete or conflicting features, undermining the quality of the Increment.
D. The Scrum Teams coordinate their work to deliver a single Increment:
Scrum Teams working on the same product must coordinate closely to ensure that they deliver a single, unified Increment. This coordination typically involves regular communication, alignment on goals, and synchronization of work to avoid conflicts and ensure that all components work together seamlessly.
Why the Other Options Are Less Appropriate
A. Code is merged at the Scrum of Scrums:
The Scrum of Scrums is a coordination meeting, not a point where code is merged. Merging code is an ongoing activity that should be part of the teams’ continuous integration practices, not something deferred to a particular meeting.
C. Each Scrum Team should have a different Product Owner:
Having multiple Product Owners for a single product can lead to conflicting priorities and a lack of coherent direction. Typically, there should be one Product Owner responsible for the Product Backlog to ensure a unified vision and clear prioritization of work.
E. All Scrum Teams work in their own version control branch:
While teams may use branching strategies to manage their work, having each team work in isolation can lead to significant integration challenges. It is generally better to work with shared branches and continuous integration practices to reduce the risk of conflicts and integration issues.
Relevance to the PSD Exam
Understanding how to coordinate multiple Scrum Teams working on the same product is essential for the PSD exam. It highlights the importance of integration, collaboration, and delivering a single, unified Increment.
Key Takeaways
- Integration before the end of the Sprint ensures a cohesive, functional Increment.
- Coordination among Scrum Teams is essential to deliver a single, unified Increment.
- One Product Owner should typically manage the Product Backlog for a single product to maintain consistency and focus.
Conclusion
When multiple Scrum Teams work on the same product, they must coordinate their efforts and integrate their work before the end of the Sprint to deliver a single, cohesive Increment. This practice ensures that the product remains functional, high-quality, and ready for potential release at the end of each Sprint.
