In Scrum, who has the final say on what features are included in the product?

The Product Owner has the final say on what features are included in the product because this role is responsible for managing the Product Backlog, which is a prioritized list of features and requirements for the product. The Product Owner makes decisions about which items are most valuable to the business and the stakeholders, ensuring that the team's efforts are aligned with the overall product strategy and vision.

This encompasses understanding customer needs, balancing stakeholder interests, and making trade-offs regarding features, functionality, and priorities. The Product Owner collaborates closely with the Development Team to refine the Backlog and is empowered to make decisions on the product direction to maximize value delivery.

While the Scrum Master facilitates the Scrum process and helps the team operate effectively, and stakeholders provide input and feedback, neither of these roles have the authority to determine the final product features. The Development Team is responsible for delivering the work and estimates the effort needed but does not decide on the content of the product features.
