A good Definition of Done (DoD) is a critical part of Agile development that sets clear expectations for when a user story, task, or feature is considered complete and ready for delivery. It helps ensure that all work meets the necessary quality standards and is in a deployable state. Here's how to write a good Definition of Done:
Collaborate with the Team: The DoD should be a collaborative effort involving the entire Agile team, including developers, testers, product owners, and stakeholders. Gather input from everyone to ensure completeness and buy-in.
Use Clear and Specific Language: The DoD should use clear, specific, and unambiguous language to leave no room for interpretation. Each item on the DoD checklist should be easily understood by all team members.
Align with Team and Project Standards: Ensure that the DoD aligns with the team's and project's standards, practices, and constraints. Consider any regulatory requirements, coding standards, or industry best practices that apply.
Include All Necessary Activities: Define all the activities and criteria that must be completed for a user story or feature to be considered done. These activities can include coding, testing, code review, documentation, integration, and more.
Functional and Non-Functional Aspects: Cover both functional and non-functional aspects of the work. This includes functionality, performance, security, usability, and any other relevant criteria.
Testing and Quality Assurance: Specify the testing requirements, such as unit testing, integration testing, and user acceptance testing (UAT). Ensure that these tests are successfully passed before considering the work done.
Code Review and Peer Review: Include code review and peer review as essential steps in the DoD. Code should meet coding standards and be reviewed for quality and maintainability.
Documentation: Mention the documentation requirements, such as user documentation, technical documentation, and inline code comments. Ensure that documentation is up-to-date.
Automation and Continuous Integration: Specify whether automation tests need to be created and whether the code must successfully pass through the continuous integration (CI) pipeline.
Performance and Scalability: If applicable, outline performance and scalability criteria, such as response times, load testing, and capacity planning.
Regulatory Compliance: If the project requires adherence to specific regulations or compliance standards, ensure that these are included in the DoD.
Review with Stakeholders: Review the DoD with stakeholders to ensure that their expectations are met. This helps manage expectations and prevents misunderstandings.
Iterative Improvement: Recognize that the DoD can evolve over time. Periodically review and update it as the team's processes and standards mature or as the project's needs change.
Measurable and Verifiable: Ensure that each item on the DoD checklist is measurable and verifiable. Team members should be able to confirm whether each criterion has been met.
Visually Present: Make the DoD visible to the entire team, often on a physical or digital board. This reinforces the commitment to quality and reminds team members of their responsibilities.
A well-crafted Definition of Done not only helps maintain consistent quality but also promotes transparency and shared understanding within the Agile team. It ensures that all stakeholders have a common understanding of when work is complete and helps prevent misunderstandings or rework.
