Final answer:
The Product Owner defines the final scope of a committed iteration in the Scrum framework.
Step-by-step explanation:
The Product Owner defines the final scope of a committed iteration in the Scrum framework. They are responsible for prioritizing the product backlog and deciding what features and deliverables should be included in each iteration.
The Product Owner collaborates with the Development Team and the Scrum Master to ensure a clear understanding of the project goals and to adjust the scope as needed. They consider the business priorities, user feedback, and technical constraints when defining the scope.
The Scrum Master, Development Team, and Release Train Engineer may provide input and insights, but the ultimate authority lies with the Product Owner.
