PMP Practice: Identify and Analyze Conflict Sources

Juniper Bautista-Kim is leading an agile team at Electric Pangolin Co developing a machine learning recommendation engine. During the sprint review, the marketing director, Amara Okonkwo-Diallo, expresses frustration that the feature prioritization doesn't align with an upcoming product launch campaign he's planned. The product owner, Elif Karahan, counters that the current backlog order maximizes user value based on customer research and that marketing wasn't involved in recent refinement sessions. Dante responds that he wasn't invited and threatens to escalate to the executive sponsor if his features aren't moved up. The tension is visible to the entire team, and two developers exchange uncomfortable glances. What should Juniper do to address this conflict?
