PMP Practice: Determine Critical Information Requirements

Naledi Dlamini is the project manager for Silver Badger Consulting, a biotech startup developing a new diagnostic device. The product roadmap includes both regulatory compliance milestones (which require detailed documentation and sequential approvals) and user interface design iterations (which benefit from rapid prototyping and customer feedback). The executive sponsor, Yuna Park-Hashimoto, wants the project delivered in 14 months to meet a critical industry conference deadline. During initial planning discussions, the engineering team insists on using a waterfall approach for hardware development due to manufacturing constraints, while the software team strongly prefers two-week sprints with continuous deployment. The quality assurance lead warns that mixing methodologies could create integration bottlenecks. Naledi has not yet documented how these different work streams will be coordinated. What should Naledi do MOST effectively to address this situation?
