PMP Practice: Identify and Analyze Conflict Sources

Henrik Vestergaard is managing a fixed-price aerospace manufacturing project for Kwame Asante-Mensah Systems to deliver 50 custom avionics units over 18 months. The contract requires strict adherence to DO-178C certification standards and includes penalty clauses for late delivery. During the third month, conflicts emerge between engineering and quality assurance teams. Engineers want to adopt two-week iteration cycles with frequent design changes to optimize performance, citing agile benefits they've read about. The QA lead insists this violates the approved verification plan and will invalidate certification documentation already submitted to regulators. Three heated exchanges have occurred in status meetings, and the teams are now bypassing each other entirely. The project baseline and all deliverables were formally approved by the customer four weeks ago, and the change control board meets monthly. What should Henrik do to address this conflict?
