Who decides the Team PI Objective Business Value scoring after negotiation?

Business Owners are key ART stakeholders who have the primary business and technical responsibility for return on investment (ROI), governance, and compliance. They evaluate the fitness for use and actively participate in ART events and solution development. They also use a scale of 1 (lowest) to 10 (highest) to assign the business value to the team PI objectives after negotiation with the teams and other stakeholders. They typically assign the highest values to the customer-facing objectives. References: Business Owners - Scaled Agile Framework, PI Objectives - Scaled Agile Framework
