Yves learned me the real Agile based on the respect, tolerance keeping in view the entreprise targets. Somehow we shared the vision and Idea we have to meet the entreprise targets and to satisfy customers. Yves learned me the scrum life and how to organize my backlog without stress, What is and what is not acceptable, how to manage problems we can have in a geant oganisation.Thanks a lot Yves for your help and integrity.
