The beginning of the century has been prolific in rapid and radical transformations in the consultancy sector, as a result of the questioning of models of strategic diversification undertaken by several consultants. But, even if these changes constitute a barrier to the legitimacy of the sector, the truth is that this assumption has also contributed to the development of the sector study in the academic environment, especially over the last twenty years it has existed a set of substantial literature that has come to reflect the contribution, conceptualization and understanding of the nature of consulting work and the real value of consultants in the way that demonstrate value to their customers. It emphasizes two key questions. Management consulting is for whom? It should be the management consultant an internal auditor of its own performance? So, what I want to emphasize in this article is exactly one set of assumptions that allow describing a set of requirements that must be implicit in the characterization of the intrinsic characteristics of a consulting services manager, because the premise of this profession must understand that it is the professional adviser that should manage their activities and not the activities to manage the professional adviser.
