This book provides a clear, easy to digest overview of Quality Management Systems (QMS). Critically, it offers the reader an explanation of the International Standards Organization’s (ISO) requirement that in future all new and existing Management Systems Standards will need to have the same high-level structure, commonly referred to as Annex SL, with identical core text, as well as common terms and definitions. In addition to explaining what Annex SL entails, this book provides the reader with a guide to the principles, requirements and interoperability of Quality Management System standards, how to complete internal and external management reviews, third-party audits and evaluations, as well as how to become an ISO Certified Organisation once your QMS is fully established. As a simple and straightforward explanation of QMS Standards and their current requirements, this is a perfect guide for practitioners who need a comprehensive overview to put theory into practice, as well as for undergraduate and postgraduate students studying quality management as part of broader Operations and Management courses.
