Module 5 — Sourcing, traceability and the supply base
Supplier data, traceability depth and documentation that survives an audit.
Traceability claims are only as deep as their weakest tier. This module covers sourcing decisions, material receiving and warehousing records, shipment documentation, and the factory data systems behind them. The emphasis is practical: what a chain-of-custody record looks like, which tiers are usually missing, and how to test a traceability statement before you repeat it.
By the end of this module: Judge how deep a supply chain trace really goes, and where the documentation usually breaks.
Prerequisite: Module 4 — traceability is evidence about evidence.
