Creating a Definition of Done is a collaborative and iterative process that involves the whole product team, as well as the stakeholders and the customers. To begin, you should start with the vision and goals of the product, and identify the main features and functionalities that are essential for the product to deliver value and solve the problem. Additionally, you should define the quality standards and acceptance criteria that each feature and functionality must meet, such as performance, usability, security, and reliability. Furthermore, you should define the technical and operational requirements that each feature and functionality must meet, such as code quality, testing, documentation, and deployment. Additionally, you should define the verification and validation methods that will be used to check and confirm that each feature and functionality meets the DoD, such as reviews, demos, and user testing. Finally, you should document and communicate the DoD to the team, the stakeholders, and the customers, and make sure everyone understands and agrees on it. It is also important to review and update the DoD regularly, based on the feedback, the changes, and the learnings from the product development process.
