What is the Definition of Done?

This shared definition helps eliminate misunderstandings about what "finished" means and ensures that everyone on the team is aligned on quality standards. The DoD can evolve over time as teams mature, technologies change, and companies learn from experience. With a clear boundary between work in progress and work that's genuinely complete, teams can maintain consistent quality and avoid the accumulation of technical debt.

Establishing a Definition of Done is an essential step to define clarity and alignment across the entire development team and stakeholders. It eliminates subjective interpretations of what is completed work. A well-defined DoD offers several critical benefits:

• Creates clear expectations for quality standards across all team members.
• Prevents technical debt accumulation by ensuring thoroughness.
• Reduces rework by catching issues before they are considered complete.
• Improves estimation accuracy since the full scope of completion is understood.
• Boosts transparency with stakeholders about what "done" actually means.
• Provides a framework for continuous improvement by revisiting the definition.

Without a clear Definition of Done, teams risk inconsistent quality, miscommunication, scope creep, and diminished trust between development teams and business stakeholders.

Acceptance criteria and Definition of Done serve different but complementary purposes in the software development lifecycle. Acceptance criteria are specific to individual user stories or features and define the precise conditions that must be met for that particular item to satisfy business requirements and user needs. In contrast, the Definition of Done applies to all work items and represents the level of quality that every increment must satisfy, regardless of its specific functionality.

Acceptance criteria vary from story to story and typically focus on functional aspects like behavior, performance, and user interactions related to that specific feature. DoD, on the other hand, focuses on broader quality aspects such as code quality standards, testing requirements, documentation, and compliance considerations that remain consistent. Acceptance criteria answer "Is this specific feature working as intended?", and the DoD answers "Is this work ready for release with sufficient quality?" In that sense, both elements work together to create a comprehensive quality assurance framework.

The Definition of Done is a way to create a shared understanding that benefits both a development team and customers in multiple ways. This approach, which is a critical part of Scrum and Agile team workflows, establishes a clear meaning of "complete," provides a built-in quality assurance mechanism, and ensures consistent product quality. These help the development team understand how to allocate resources and prioritize tasks to achieve their DoD. Likewise, this reduces the chances of redoing work that has already been done.

With the Definition of Done, customers receive consistent product quality and reliability, along with greater transparency about the results. This practice also ensures that technical implementation aligns with business value. This allows the development team to verify that all necessary aspects are present to deliver products that better meet customer needs. The shared understanding created by a well-defined Definition of Done connects technical execution and business requirements, which can come into conflict without such clear requirements.
