This arises from the fact that in order to grow for a company; it should take into account the commitment and variation in this regard, in their clients. In this article the growth options of PyMes based upon the search for standardization, certification and the implementation of their processes with the aid of standard norms such as ISO 9000 are highlighted. This process should be on the basis of the level of the commitment of all their employees, as in the absence of such commitments, such processes will be viewed as unnecessary costs which will not help the growth of the company.
