This book will be of particular interest to those who have used BS 15000 for service improvements, audits or training and need to update their material to reflect the BS ISO/IEC 20000 standard.

BS ISO/IEC 20000 was based on BS 15000, and this book provides a detailed comparison of BS ISO/IEC 20000 and BS 15000, for both Parts 1 and 2. It shows the differences in structure, clause numbering and references.

The core of this book is a series of tables detailing the changes to the requirements and recommendations clause-by-clause, as well as any re-wording that has been provided to give clarification for an international audience.

It includes an explanation of why the changes were made and the implications of each of the changes. This book is based on the material produced by the Project Editor during the drafting of both Parts 1 and 2 of BS ISO/IEC 20000.
