This book might never have seen the light of day were it not for the support, the advice and the experiments conducted alongside all those who have worked on the subject of this book.
First, I would like to thank Samir Lamouri, Professor at ParisTech Arts et Métiers, for his encouragement and support during my research and Jean Luc Paris, Professor at IFMA, for his expert contributions.
I would also like to thank Michel Favre Bertin, who initiated the SCALE model and has contributed his experience with evaluation frameworks throughout the many years that we have worked together, for helping with the implementation of new supply chain audit approaches and his partnership in conducting company audits.
Next, I would like to thank all the ISLI students at KEDGE Business School, who were involved in the studies designing and implementing the company auditing tools. Through their innovative ideas and capacity for hard work, I gained further insights and ideas, without which this book might not have been possible.
Finally, I would like to offer particular thanks to my wife Laurence and my two sons Théo and Timothé for their unfailing support.
