Q: What is a quality management system?

A: A quality management system (QMS) defines and establishes an organization's quality policy and objectives. It also allows an organization to document and implement the procedures needed to attain these goals. A properly functioning QMS ensures that procedures are carried out consistently, that problems can be identified and resolved, and that the organization can continuously review and improve its procedures, products and services. It is a mechanism for maintaining and improving the quality of products or services so that they consistently meet or exceed the customer's implied or stated needs and fulfill their quality objectives.

ISO 9001, Quality management systems - Requirements, outlines the essential characteristics of an ISO 9000 quality management system.
