The DoD should be the same for all the teams


The Definition of Done applies to the Product Increment (not to Product Backlog items like User Stories) which is potential releaseable. Every team can have it’s own Definition of Done, but when multiple teams are working on the same product, they have to deliver one integrated Product Increment by the end of the Sprint. And to assure that this integrated Increment is Done, all teams must have the same Definition of Done, but each team is free to extend their own DoD.
