An Increment is the sum of all the product items completed during a sprint. At the end of the sprint, the increment must be useable and should meet the team's definition of done.
The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product.
If the Definition of Done for an increment is part of the standards of the organization, all Scrum Teams must follow it as a minimum. If it is not an organizational standard, the Scrum Team must create a Definition of Done appropriate for the product.
