Definition Done

DoD is a shared understanding of what is a potentially releasable, useable, complete Increment.

It provides a transparency to the Scrum team.

Before the Sprint Planning, the Scrum Team has the shared understanding of the DoD.

During the Sprint Planning, the DT bases on the DoD to forecast how many PBIs it will complete in the upcoming Sprint.

During the Sprint Execution, the DoD guides the DT how to convert the PBIs to a potentially releasable, useable, done Increment.

During the Sprint Review, the DoD is the shared understanding to justify if the PBIs selected are done.

During the Sprint Retrospective, the Scrum Team may improve the DoD to approach a higher quality.

In any given Sprint, the DoD is first applied during Sprint Planning. It helps the Development Team understand the work that will be required to make the increment release-ready, and to plan that work accordingly.

However the DoD may be referenced before that Sprint, during Product Backlog refinement in earlier sprints. The DoD helps the team to understand the work involved in making Product Backlog Items of release quality, and to provide each item with an appropriate estimate.
