PMP Practice: Consolidate the project/phase plans

Birch Volkov is leading a predictive project to upgrade the customer relationship management system for Bold Ridge Labs, a freight and warehousing company operating across twelve distribution centers. During integrated planning, Kira has received component plans from the procurement lead, technical architect, training manager, and change management consultant. The procurement lead's timeline assumes vendor equipment will arrive in six weeks, but the technical architect's infrastructure plan requires nine weeks for data center preparation before equipment installation can begin. The training manager's schedule shows customer service staff training starting in week eight, but the change management consultant's stakeholder assessment indicates that regional managers—who supervise those staff—have not yet been engaged and may resist the new system. Kira needs to reconcile these plans into a cohesive project schedule and budget. Which approach would be MOST effective for integrating these component plans?
