Following technological developments and the overall economic situation, companies use a logic of innovation to survive in a competitive environment. These industries have become aware of their own wealth: human potential. For some years, they have been using a tool of participative management, the reaction report. They use the reaction of new agents to improve their techniques. Just like companies, hospitals undergo constraints: accreditation, control of expenses, and optimization of human and material resources. These are many factors which require health professionals to adapt to improve the services offered to the patients. The developments with which health establishments are confronted oblige them to show initiative, creativity, and to exist within a dynamic of change. They are increasingly seeking the involvement and participation of agents to ensure their primary mission: to meet the population’s care needs. As a consequence, so as to promote the participation of their personnel, health establishments are understandably inspired by this tool of management. But it is not easy to get a new method into people’s habits. The reaction report can, however, be an efficient and relevant tool in the world of health. It can reveal itself as an essential asset in participative management and in a quality approach which has become a legal and statutory requirement.
