Balancing Quality and Velocity in Scrum
Achieving high velocity is often seen as a measure of a team’s productivity in Scrum, but it should never come at the expense of quality. This article explores a specific exam question about balancing quality and velocity in Scrum, providing detailed explanations and insights relevant to the PSM II exam.
Exam Question
In the Sprint Retrospective, there is discussion that the quality of the Increment is not sufficient for going to production. In response, a Scrum Team member points out the high velocity reached by the team. What are the two best actions for the Scrum Master to take? (choose the best two answers)
- A. Stress the value of working product over measured velocity.
- B. Agree and praise the Developers for their hard work, so they are motivated to do even more in the next Sprint.
- C. Acknowledge the hard work but remind the Developers that they need to improve in order to do even more in the next Sprint.
- D. Facilitate a discussion on how to improve the quality to a level sufficient for production, even if the measured velocity will drop in the next Sprint.
Correct Answers
A. Stress the value of working product over measured velocity.
D. Facilitate a discussion on how to improve the quality to a level sufficient for production, even if the measured velocity will drop in the next Sprint.
Explanation
Correct Answers
A. Stress the value of working product over measured velocity: The primary goal of Scrum is to deliver a potentially releasable Increment at the end of each Sprint. A high velocity is meaningless if the quality of the product is insufficient for production. Emphasizing the importance of a working product reinforces the focus on delivering value to the customer.
D. Facilitate a discussion on how to improve the quality to a level sufficient for production, even if the measured velocity will drop in the next Sprint: The Scrum Master should guide the team in addressing quality issues and finding ways to improve. This might involve implementing better testing practices, improving the Definition of Done, or other quality assurance measures. The focus should be on delivering a high-quality product, even if it means reducing velocity temporarily.
Incorrect Answers
B. Agree and praise the Developers for their hard work, so they are motivated to do even more in the next Sprint: While recognizing hard work is important, praising high velocity without addressing quality issues can reinforce the wrong behavior. It might lead the team to continue prioritizing speed over quality.
C. Acknowledge the hard work but remind the Developers that they need to improve in order to do even more in the next Sprint: Similar to option B, this approach fails to address the core issue of quality. Encouraging the team to do more without focusing on improving quality can result in further technical debt and a subpar product.
Responsibilities in Scrum
- Product Owner: Ensures that the Product Backlog items are clear and that the quality standards are understood and met. They focus on maximizing the value of the product.
- Scrum Master: Facilitates Scrum events, coaches the team on Scrum practices, and helps remove impediments. They ensure that the team maintains a balance between speed and quality.
- Developers: Responsible for delivering a potentially shippable Increment at the end of each Sprint. They ensure that their work meets the Definition of Done and adheres to the agreed-upon quality standards.
Relevance to the PSM II Exam
Understanding the importance of balancing velocity and quality is crucial for the PSM II exam. It demonstrates advanced knowledge of Scrum practices and the ability of the Scrum Master to guide the team in delivering high-quality products consistently. Mastering this concept ensures that Scrum Masters can support their teams in continuous improvement and delivering real value to the customer.
Key Takeaways
- High velocity should not come at the expense of product quality.
- The Scrum Master’s role includes facilitating discussions to improve quality and ensuring that the team adheres to the Definition of Done.
- A working product that meets quality standards is more valuable than simply achieving high velocity.
Conclusion
Balancing quality and velocity is essential for the success of any Scrum Team. By focusing on delivering high-quality Increments and continuously improving their practices, Scrum Teams can achieve both high productivity and high quality. Understanding these principles is crucial for effective Scrum implementation and success in the PSM II exam.
