PMP Practice: Implement Approved Changes

Ariki Māhaki is managing a hybrid project for Intentional Serendipity Co to develop a sustainability analytics platform. The predictive infrastructure build is complete, but the agile product team is iterating on the dashboard features. During a recent sprint review, the compliance officer demanded immediate integration of new ESG reporting requirements that will be mandatory in three months. The product owner wants to deprioritize this work to focus on customer-requested visualizations that generate immediate revenue. The change would require approximately 15% additional development effort and would impact the planned go-live date. The project governance framework requires documented change approval for any work affecting baseline schedule or budget, but the agile team is accustomed to reprioritizing work within sprints based on product owner decisions. Which approach would be MOST effective for managing this situation?
