Who creates the definition of "Done"?

The definition of "Done" is primarily established by the development organization as a whole, incorporating input from the Development Team. This definition is crucial as it sets the criteria for when a product increment is considered complete and usable. It is not solely the responsibility of the Product Owner, Scrum Master, or any single stakeholder; instead, it ensures that everyone involved in the development process is aligned on what constitutes completion, quality, and adherence to set standards.

The development organization includes the Development Team, which actively participates in defining and refining this definition through the various Scrum events. The definition of "Done" is intended to be clear, shared, and understood by all members of the Scrum Team, making it a collaborative effort to maintain transparency and accountability across the organization. This collective approach helps to ensure a shared understanding of quality across all increments delivered.
