A bible to read for all transformation agents and leaders!

Jérôme Lavancier, Program Director Agile@Scale Transformation Coordination chez Société Générale

Rather than offering us yet another series of case studies or a list of best practices that have been covered to death, Olivier Zara offers us a real model for achieving decision-making excellence and thus managing decision-making risks in complex situations.

Arnaud Brouxel, ex-Safran & Thales, Risk Management Expert

After reading this book, you will question your way of deciding and much more!

Charles Didier, Transformative Business Leader at Huntsman Corporation

This book proposes a robust and coherent model for managing complexity and crises, but it also invites us to value our human, ethical and altruistic qualities. Are you ready to take a journey into a 21st century enterprise?

Paul-Louis Moreau, Change & Digital Transformation Manager at BNP Paribas

A relevant book, given the context of the COVID-19 crisis, which offers a holistic and systemic reflection on decision-making intelligence. This book allows us to better understand (theory) and approach (practice) this complex subject in a more accurate way, both by making us aware of the benefits of new managerial approaches and by revealing the causes of failure of organizational transformation projects and programs. To be put in the hands of all decision-making agents within organizations.

Sabrina Bouraoui, Leadership Development Consultant, Founder of Shades of Gray

I strongly recommend reading this book if you feel the need to secure your decision making process in a complex and uncertain environment (which you should!). Are you sure you're running in the right direction? You will find tools and best practices to renew your change management habits. Aimed at leaders, managers and consultants.

Florence Meyer, Coach & Leadership Consultant, Speaker & Author

If you are concerned by decision-making process, Olivier’s book is a real must-read book if you seek to survive in a complex environment.

Marc Weltmann, CEO of Nexidée, International Purchasing Specialist

An indispensable book to understand this complex subject from all perspectives and discover the benefits of new managerial approaches.

Olivier Bernard, Deputy Director of Flight Safety at Air France

This book is a treasure trove of explanations on the causes of failure in business transformation projects and programs. The Decision-Making Excellence Manifesto should not be included as an appendix to this book, but on the syllabus of all management schools!

Charles Escoula, Project Manager at AVEM-group

Olivier Zara’s sassy, iconoclastic and fresh new opus provides techno-language-free incisive and useful advice to make decisions that work! This book reveals a very powerful technology yet as old as homo sapiens to make it happen. A must "read & test" without moderation!

Thierry Roussin, Founder at Aguialabs, Changemaker in Disruptive Innovation, Impact Investing, and Venture Philanthropy to drive Societal Change

Olivier presents his model and framework with a clear and precise approach and processes. He has a great talent for writing in a simple but never simplistic way. We feel the depth and experience behind his words.

François Lavallée, organizational biologist, Founder of AliterConcept www.aliterconcept.com

The work behind this book is colossal. One feels that it is the fruit of a long experience. Inspiring and pragmatic, this book invites us to take action in a world that must change. The stakes of ecology and globalization, undermined by a simple virus, are just a few reasons. It is no longer time to look for heroes who know everything, it is time to use collective intelligence to enable our decision-makers to make the best decisions. Olivier Zara explains how to use collective intelligence effectively and coherently in the enterprise. And above all, he doesn't just tell you what to do, he tells you why!
