Abstract
This chapter presents the seven models of access to power as observed in France: the "chosen few", the examination, seniority, the pick-of-the-crop model, the baronial model, the professional model, and the meta-model of diversity which begins with an analysis of the situation then the choice of intervention to best develop the dominant model. This meta-model raises the question of just how much executive diversity or homogeneity is required in the firm, particularly in firms that are international and formed from expansion.
