A Review - Quality Assurance & Quality Control

Abstract

Quality Assurance (QA) and Quality Control (QC) are complementary systems ensuring product quality, with QA being process-focused and preventative (building quality in through standards and procedures) and QC being product-focused and reactive (inspecting and testing to find defects in finished goods). Together, QA sets the framework and QC verifies the outcome, both vital for meeting customer needs, adhering to regulations, and delivering safe, effective products in fields from software to pharmaceuticals.
