This collective intelligence manifesto presents powerful concepts and practical advice, in particular silent meetings, the combination of oral and written communication and the role of the chief to enhance the intelligence of his employees.

We already knew that leaders eat last, they should also talk last according to Olivier Zara! Otherwise, everybody will agree with the manager / expert and the meeting will not effectively solve problems. This is not so easy to implement; therefore Olivier Zara gives us a methodology, tools and actionable tips to keep quiet during a meeting and bring out the best ideas of the team.

Florence Meyer, Coach & Leadership Consultant, Speaker & Author

Olivier Zara is once again taking one step ahead in management tools, by rebuilding the distribution of speech in a team or a group. This is a triple victory: employee engagement, the good health of organizations, which are thus vaccinated against toxic practices, and operational performance with an unequalled problem-solving capacity.
