The modes of organization and management of entrepreneurial processes are subject to influences and even reactive effects exerted by the overall management of the economy. A historical perspective makes it possible to link this particularity to the entrepreneurial policies pursued at least from the launch of industrialization plans in the early 1970s. The main objective of the analysis is to show that the exogeneity of the logics of reproduction of entrepreneurial processes has powerful effects on their modes of organizational structuring and governance, on the choices of their commitments and on the inter-functional relationships to be maintained between them. On an empirical level, the task consists of reconstituting the organizational and managerial realities of large private groups (NCA ROUIBA, GENERAL EMBALLAGE, SIM, AMOR BENAMOR, etc.), of establishing the structure and origin of their skills and the nature of their strategic movements (diversification or conglomeration strategy, succession or takeover strategies, etc.). The results of the explorations and analysis (historical and qualitative) of entrepreneurial processes are of four types: Low complexity of production functions and inter-functional entrepreneurial relationships in the economy. Also, development of unrelated forms of diversification in the economy in reason for the distrust maintained towards large size at the political level. Additionally, the subordination of the evolution of private capital to the managerial capacities offered by the family space. Finally, with the shift of competition from goods markets towards the spheres of access to regulated entrepreneurial resources.
