Since the publication of the first edition of this book in 2000 the revised ISO 9001 standard has been implemented and is being used widely. While the basic premise of the original book is still sound the reality of auditing the new standard has shown up various areas which require refinement - this new edition addresses that need. It remains a pragmatic guide, covering all aspects of auditing, including certification assessment, supplier investigation and internal audit, enabling auditors to appreciate the approaches adopted by those working in related areas. With its detailed analysis of the requirements of ISO 9001:2000, this book will also be of interest to all those involved in implementing certified quality management systems, as well as the auditors who are required to examine those systems.
