Benefits of a Good Definition of Done
A well-crafted Definition of Done (DoD) is essential for ensuring that the Scrum Team maintains high-quality standards and consistently delivers valuable Increments. It provides clarity and sets the framework for what is considered complete in the development process.
Exam Question
What are the top three benefits of a good Definition of Done?
(choose the best three answers)
A. A full description of all test steps.
B. Clear communication of the Scrum Team’s quality standards.
C. Guidance on the specific patterns to be implemented in code.
D. A fully valuable, useful Increment by the end of each Sprint.
E. An ongoing strategy or technique for steadily addressing technical debt.
Correct Answers
B. Clear communication of the Scrum Team’s quality standards.
C. Guidance on the specific patterns to be implemented in code.
E. An ongoing strategy or technique for steadily addressing technical debt.
Explanation
Correct Answers
B. Clear communication of the Scrum Team’s quality standards:
The Definition of Done provides a shared understanding of the quality standards that the Scrum Team adheres to. This ensures that all team members know what is expected for an Increment to be considered complete and ready for release. This clarity helps maintain consistency in the quality of the work delivered.
C. Guidance on the specific patterns to be implemented in code:
The Definition of Done can include guidelines on the coding patterns and practices that should be followed. This helps ensure that the codebase remains consistent, maintainable, and adheres to best practices, which is crucial for long-term sustainability and quality.
E. An ongoing strategy or technique for steadily addressing technical debt:
By incorporating strategies to manage technical debt into the Definition of Done, the Scrum Team can steadily address and reduce technical debt over time. This proactive approach helps prevent the accumulation of technical debt, which can degrade the quality of the product and slow down future development efforts.
Why the Other Options Are Less Appropriate
A. A full description of all test steps:
While testing is important, the Definition of Done does not need to include a detailed description of every test step. The focus should be on ensuring that the necessary quality checks are completed, not on detailing every test step.
D. A fully valuable, useful Increment by the end of each Sprint:
While delivering a valuable Increment is the goal of every Sprint, it is the outcome rather than a direct benefit of the Definition of Done. The Definition of Done focuses on setting the criteria that must be met to consider the work complete, not on the delivery itself.
Relevance to the PSD Exam
Understanding the benefits of a good Definition of Done is crucial for the PSD exam, as it emphasizes the importance of clear quality standards, code consistency, and technical debt management in delivering a high-quality product.
Key Takeaways
- Clear communication of quality standards ensures consistency and shared understanding within the team.
- Guidance on coding patterns helps maintain a consistent and maintainable codebase.
- Addressing technical debt as part of the Definition of Done helps maintain long-term product quality and sustainability.
Conclusion
A good Definition of Done is vital for maintaining high-quality standards, guiding coding practices, and managing technical debt effectively. It ensures that the Scrum Team has a clear understanding of what is expected and maintains a consistent standard of work across all Sprints.
