PMP Practice: Implement Resolution Strategies

Dakota Chen-Blackwood is managing a 14-month infrastructure upgrade project for Jugaad Innovation Corp, a biotech research facility. Two senior team members—Diego, the network architect, and Lila, the security lead—have been in escalating conflict over firewall placement strategy. Diego insists on deploying at the network perimeter for performance reasons, while Lila demands segmented internal firewalls to meet compliance requirements. The conflict has now spilled into team meetings, with both refusing to collaborate on the integrated design document due next week. Other team members report feeling uncomfortable and avoiding involvement. The project's critical path includes finalizing this design within five days to avoid delaying hardware procurement. Dakota has confirmed that both approaches have technical merit and that a hybrid solution is feasible but requires joint analysis. What should Dakota do to resolve this conflict?
