Abstract EN:

Since 1965, I have tried, through all my works, to find answers to the failures management has encountered in the western world as a consequence of the world widening relationship. In 1985, the results of these works led to the following interrogation: has management been altered by any phenomenon engendering an epistemological change similar to the one due to the emergence of quantum mechanics that happened in physics? In order to answer this question, i began to check the relevancy of such an assumption. First of all in a diachronic way, studying closely my work's evolution from 1965 to 1985, and then in a synchronic way investigating in both the assessment of a real convergence within contemporary epistemological changes and the springing of convergent evolvement of innovation within the management's methods. It then appeared that this phenomenon could be imputed to the emergence of the "subject" behind the "actor". As far as western humanism is concerned, this explanation seems to be fully relevant. In fact this emergence gives birth to a particular epistemological change. When going further in the implementation of this change, emergence of the "subject" behind "actor" could be translated by less syncretism in management. It can be pointed out that management syncretism has brought numbers of socio-economical failures. Moreover, the emergence of the "subject" behind the "actor" helped to build up a background of references out of which new steps could be taken in management. Action research belongs to these specific schemes? It gives evidence that, beyond the paradigm of modernity, both scientific knowledge and action could be allied in a new way.
