What is a Quality Management System?

A Quality Management System (QMS) is a structured framework that documents and improves all processes, products, and services to meet customer expectations. ISO 9001 is the world's most recognized QMS standard, adopted by millions of organizations globally. A QMS ensures consistency, reduces errors, and drives continuous improvement.
