Supplier CAPA Review: Evaluating the Effectiveness of Supplier Corrective Actions

Why Supplier CAPA Effectiveness Matters When a supplier quality issue is identified — whether through incoming inspection, customer complaint, audit finding, or process monitoring — the corrective and preventive action (CAPA) taken by the supplier determines whether the issue is truly resolved or merely patched temporarily. Ineffective supplier CAPAs lead to recurring quality issues, supply chain disruption, customer dissatisfaction,…
