The best way for multiple Scrum Teams to deliver a valuable and useful Increment in a Sprint is to complete work that integrates with all of the other work from other Scrum Teams on the initiative. This means that the Scrum Teams collaborate and coordinate their work to produce a single Integrated Increment that meets the Definition of Done and the Product Goal. The Integrated Increment is the combined work of all the Scrum Teams that is potentially releasable and provides value to the customers and stakeholders 11.

The other options are not correct for the following reasons:

Each Scrum Team delivering done Increments of its own area of responsibility and integrating them into a whole product during stabilization prior to release is not a good idea, as it violates the Scrum principles and values. The Scrum Guide states that the Scrum Team delivers a product Increment that is usable and valuable at the end of every Sprint, not at the end of the release 22. Delaying the integration until the stabilization phase would compromise the transparency, the feedback, and the adaptability of the Scrum Teams.

Each Scrum Team providing a unique done Increment that includes the team’s added functionality is not a good idea, as it does not ensure that the product Increment is integrated and consistent across the initiative. The Scrum Guide states that the product Increment is the sum of all the Product Backlog items completed during a Sprint and all previous Sprints 22. If each Scrum Team provides a unique Increment, they may not be aligned with the Product Goal and the Definition of Done, and they may create conflicts or dependencies with other Scrum Teams.

Functionality not integrated with the work of other Scrum Teams being delivered as unintegrated Increments to demonstrate the value created by the Scrum Teams unable to completely integrate their Increments is not a good idea, as it does not ensure that the product Increment is done and valuable. The Scrum Guide states that the product Increment must be usable and meet the Definition of Done 22. If some functionality is not integrated with the work of other Scrum Teams, it may not be usable or valuable to the customers and stakeholders, and it may introduce technical debt or quality issues.
