Conclusion
Strategic management and corporate governance

Since the late 1970s, strategic management has been enriched by numerous concepts, models and practices, notably imported from law, political science, economics, sociology and psychology. The result has been a diversification of representations of the company, a doubling of its dimension – both organizational and institutional – and, consequently, a renewal of approaches to diagnosis and strategic decision-making, as well as to the management of organizational and cultural change within the company. These changes have helped to transform corporate executives into "complexity managers" and "leaders" of socio-professional groups and networks (see table 6 ).
