Supplier Quality Assurance ensures that externally sourced materials, components and processes meet quality and regulatory requirements. Distinct from internal/in-process quality and from design quality, this focus centers on the supply base: qualifying and auditing suppliers, driving supplier corrective actions (SCAR/8D), applying advanced product quality planning (APQP/PPAP/FAI) before mass production, monitoring supplier KPIs, and partnering with procurement and engineering to prevent defects and reduce variation across the supply chain.
