Final answer:
The correct answer to how multiple Scrum Teams should deliver a done, useful, and valuable Increment is: c) Teams collaborate to deliver a shared Increment.
Step-by-step explanation:
Multiple Scrum Teams should work together to create a single cohesive Increment by collaborating during the Sprint to produce a potentially shippable product increment. The Product Owner helps align the teams with the product vision.
In the context of Scrum, when multiple Scrum Teams are working on the same product, they should coordinate their efforts to create a single cohesive Increment by the end of each Sprint. This is because Scrum favors cross-functional teams that work together to achieve project aims and work towards producing a potentially shippable product increment at the end of each Sprint. It is not a task designated to a single role like the Product Owner or the Scrum Master; rather, it is a collective effort.
The Product Owner is responsible for maximizing the value of the product and works with the Scrum Teams to ensure that the right work is being done. As such, collaboration among the teams is essential to align the development efforts and ensure that the product evolves in a coherent way with all teams contributing to the overall vision and goals set by the Product Owner.
