PMP Practice: Implement Resolution Strategies

Marisol Santos-Reyes is facilitating the sprint retrospective for her agile team at Lagom Logistics, a mobile game development studio. During the retro, two senior developers—Kenji and Lila—begin a heated argument. Kenji insists the team should focus exclusively on new features to meet the roadmap commitments made to stakeholders. Lila argues the team must allocate at least 30% of capacity to refactoring technical debt, which has accumulated over the past four sprints. Both developers are visibly frustrated, and other team members are becoming uncomfortable. The team's velocity has dropped 25% over the last two sprints, and the product owner has expressed concern about missing the upcoming release milestone. Which approach would be MOST effective for managing this conflict?
