Supply Chain Traceability
Supply chain traceability is the ability to identify, for any component in any shipped unit, its origin (supplier, lot or batch, certificates and handling) and, in the forward direction, every unit that consumed a given supplier lot. It links the as-designed product record and approved vendor list in PLM with the as-built lot and serial consumption captured in MES, extended upstream through supplier data.
In context
A brake caliper supplier reports that one casting lot was heat-treated out of specification. The OEM queries MES for every vehicle that consumed the lot, finds 1,140 units across two plants, pulls their configurations and owners from PLM and the dealer system, and issues a targeted recall within 48 hours. Without lot capture it would have recalled every vehicle built in the six-week window.
Why it matters
Traceability is what turns a supplier quality escape into a bounded service action rather than a population-wide recall, and what lets a manufacturer answer a regulator's origin question at the part level. It is increasingly a legal requirement under the EU Digital Product Passport, REACH, conflict minerals rules, FDA UDI and AS9100.
