When multiple Scrum Teams are working together, what must they mutually define?

When multiple Scrum Teams are collaborating on the same product or project, it is essential for them to mutually define their Definitions of Done. The Definition of Done is a shared understanding of what it means for a piece of work to be considered complete. This agreement ensures consistency across teams, allowing for a unified approach to quality and delivery.

By having a collectively established Definition of Done, all teams can ensure that they are meeting the same quality standards and that the output is cohesive when integrated. It fosters transparency and accountability and minimizes the risk of discrepancies in how work is completed across different teams.

In the context of the other options, while Product Goals, Sprint Goals, and team compositions are important, they do not necessarily require mutual definition among all Scrum Teams. Product Goals can be aligned but typically reside at the product level rather than individual team levels. Sprint Goals are defined by individual Scrum Teams for their respective Sprints, reflecting their specific focus for that iteration, and team compositions relate to the internal structure of each team rather than collaborative work across teams. Thus, mutual agreement on the Definition of Done is crucial for ensuring seamless collaboration and achieving a shared vision of the product’s quality.
