This presentation shows how Tier-1 manufacturers can reduce supply-chain risk by embedding rules-based supplier governance directly into PTC Windchill BOM generation. By applying cascading business rules (OEM, plant, and component-level) to enforce approved/excluded suppliers and compliance constraints, organizations can eliminate duplicate part numbers, improve traceability, and produce audit-ready BOMs in minutes—validated through a real-world Tier-1 automotive case study.
