Product traceability is a critical component of quality assurance (QA) systems, particularly in industries where safety, compliance, and consumer trust are paramount. Traceability ensures that every product can be tracked throughout its lifecycle—from raw materials to production, distribution, and end use. This capability is essential for identifying and addressing quality issues, managing recalls, and meeting regulatory requirements. This article delves into the concept of product traceability, its significance in QA, methodologies for implementation, and the challenges and benefits associated with a robust traceability system.
