BMW PartChain: Automotive Supply Chain Transparency

The Challenge: Automotive supply chains involve numerous players across multiple delivery stages with frequent changes. BMW needed to ensure seamless traceability of components and raw materials to prevent counterfeits, verify quality compliance, and meet regulatory requirements. Traditional EDI handled transactions but couldn't provide tamper-proof verification of component origins.

The Solution: BMW developed PartChain, using cloud technologies (Amazon Web Services, Microsoft Azure) combined with blockchain to track component origins between all participating partners without risk of manipulation. The 2019 pilot focused on purchasing front lights, involving two BMW plants and supplier Automotive Lighting. EDI continues handling purchase orders and invoices, while blockchain records critical verification events.

The Results:

  • Expanded implementation: Platform rolled out to ten suppliers in 2020

  • Tamper-proof tracking: Origin of components tracked between all partners without manipulation risk

  • Data privacy maintained: Standardized and anonymized format ensures security

  • Long-term roadmap: Plans to extend beyond parts to track critical raw materials from mine to smelter

  • Industry collaboration: BMW co-founded Mobility Open Blockchain Initiative (MOBI) in 2018, comprising 120+ automotive, mobility, and technology companies developing common standards.
