Responsibilities of Testers in a Scrum Team
In Scrum, there is no separate role for testers; instead, the responsibility of ensuring quality is shared among the Developers. This approach promotes collaboration and collective ownership of the product quality.
Exam Question
What are two responsibilities of testers in a Scrum Team? (choose the best two answers)
- A. Scrum has no “tester” role.
- B. Finding bugs.
- C. Verifying the work of programmers.
- D. Tracking quality metrics.
- E. The Developers are responsible for quality.
Correct Answers
A. Scrum has no “tester” role.
E. The Developers are responsible for quality.
Explanation
Why A and E are Correct
A. Scrum has no “tester” role: In Scrum, there are no predefined roles such as testers or quality assurance engineers. Instead, the Scrum framework promotes a cross-functional team where Developers take on various responsibilities, including testing and ensuring the quality of the product.
E. The Developers are responsible for quality: The Developers in a Scrum Team are collectively responsible for the quality of the product. This means they must ensure that all work meets the Definition of Done, which includes rigorous testing and validation.
Why B, C, and D are Incorrect
B. Finding bugs: While finding bugs is part of ensuring quality, in Scrum, this responsibility is not assigned to a separate tester role but is a collective responsibility of the Developers.
C. Verifying the work of programmers: Verification of work is part of the collaborative effort among Developers, rather than being a distinct responsibility of a separate tester role.
D. Tracking quality metrics: Although tracking quality metrics is important, it is not a specific responsibility assigned to testers in Scrum. The Scrum Team as a whole focuses on delivering quality through continuous improvement and adherence to the Definition of Done.
Key Points
- Cross-Functional Team: In Scrum, all Developers share the responsibility for quality, including testing and verification.
- Collective Ownership: Ensuring quality is a collective effort, with no separate tester role.
Responsibilities in Scrum

Understanding the responsibilities of the Scrum Team, particularly the collective ownership of quality, is crucial for the PSM I exam. This knowledge highlights the importance of cross-functional teams and the absence of traditional roles such as testers in Scrum.
Conclusion
In Scrum, there is no separate tester role. Instead, the Developers are collectively responsible for ensuring the quality of the product. This approach promotes collaboration, shared responsibility, and continuous improvement within the Scrum Team.
