The definition of 'Done' can be prepared in the development organization and used in all projects as a minimum. If additional content is required for the definition or it's not prepared in the organization level, the Development Team would
be responsible for preparing it. The definition of 'Done' can evolve during the project as more is learned. It's also dependent on the project and its environment. Multiple teams can have different definitions of 'Done', as long as
they are compatible and capable of creating an integrated Increment at the end of the Sprint.
