In software, a Definition of Done may be: “Done means coded to standards, reviewed, implemented with unit Test-Driven Development (TDD), tested with 100 percent test automation, integrated and documented.”
In a services context, it might look something like this: "Done means every task under the User Story has been completed and any work created is attached to the User Story so the Product Owner can review it and make sure it meets his or her expectations."
At Scrum Inc., a business services organization, this can include word documents, excels sheets, presentation decks, e-mails or any number of other work produced. In order for the Product Owner to accept the story these elements need to be attached to the User Story for it to be called done.
The Definition of Done ensures everyone on the Team knows exactly what is expected of everything the Team delivers. It ensures transparency and quality fit for the purpose of the product and organization. As Jeff points out in video, getting stories done can double a Teams Velocity. The slides delineate how to get stories both Ready and Done."
The Definition of Done promotes transparency by providing everyone a unified understanding of the work completed during the Increment. If a Product Backlog item doesn't meet the Definition of Done, it shouldn't be released or presented at the Sprint Review. Instead, it's returned to the Product Backlog for future consideration. If the Definition of Done for an increment is a part of the organization's standards, all Scrum Teams should follow it as a minimum. If it's not an organizational standard, the Scrum Team must create a Definition of Done appropriately for the product. The Developers (anybody who is working on the sprint increment) must conform to the Definition of Done. If multiple Scrum Teams are collaborating on a product, they must mutually define and comply with the same Definition of Done. The Definition of Done is the commitment contained in the Increment artifact.
