QA vs QC

Quality assurance refers to the systematic and proactive approach to ensuring that products, services, and processes meet or exceed customer expectations. It involves creating and implementing policies, procedures, and standards that prevent defects or errors from occurring in the first place. QA focuses on prevention rather than detection, and it is concerned with the entire production process, from design to delivery.

On the other hand, quality control refers to the reactive approach of ensuring that products, services, and processes meet established quality standards. QC involves testing and inspecting products or services at various stages of production to identify defects or errors that may have occurred. It is concerned with detecting and correcting defects before they reach the customer.
