Abstract
The small and medium sized entreprise needs specific managerial criteria, taking account of the high level of diversity among those firms. That specificity results from the global character of the management system, needing to analyse together the goals, the environment, the organization and the activities, getting concepts connecting those poles. The specificity is also due the proéminent role of the entrepreneur. Many classifications exist. It is suggested to make a distinction between the entrepreneur focusing on a patrimonial logic, and the other one focusing on a flow logic.
