PMP Practice: Leverage emotional intelligence to build trust

Ash Reyes is managing a hybrid project for Bold Pulse Labs to implement a new warehouse management system. The development team is using two-week sprints for software features, while the hardware installation follows a predictive schedule. During a sprint review, the operations director insists on adding real-time inventory tracking features immediately, claiming it's essential for daily operations. The development team pushes back, stating this wasn't in the agreed sprint scope and would disrupt their committed work. The operations director has significant influence in the organization and has historically been resistant to IT projects. Ash has already confirmed the sprint backlog was finalized three days ago with team commitment. What should Ash do to build trust and influence both stakeholders?
