While this book may serve as a textbook, it is not a theoretical book. Instead, it contains a wealth of practical knowledge collected by the editorial board. This practical knowledge and the introduction to the field of IT service management make the book useful even for those not preparing for the examination. Since no single publication can have the answers to all the questions that arise in a field so multifaceted as IT Service Management, the aim of the book is to raise key questions, to encourage discussions and the comparison of the best practices found in the book with the reader"s own experience.
