If you have more than one Scrum team working on the same product, they must share a minimum Definition of Done. These are common quality checkpoints that every team has agreed to execute before calling the product backlog item “done.” Individual teams are welcome to have a larger DoD but the organizational DoD must be common among all teams. Individual teams should strive to have a DoD that gets as close as possible to production. Do keep in mind that the full product will be completed as fast as the slowest team. Thus, as teams expand their individual DoD, the organizational DoD should also expand once all other teams have adapted the new steps.
