If we have been able to arrive at one first stage of growth in which already a very considerable number of clients is had and the suitable mechanisms settle down to know them deeply and to extract the necessary information, we have the possibility of being able to send to products services that satisfy every better time their necessities and, this way, to still obtain many more clients. Consequently, to manage to raise a second step in the growth stairs. The competitors who do not have this knowledge that provides the volume of clients, hardly will be able to know what improvements must do in products and, therefore, to enter this dynamics. Finally, a company also can enter a dynamics of increasing yields by the fact that its model of business enjoys the effect learning. This situation we found it, specially, in intensive companies in knowledge, that is to say, every time in more companies. If the model has east effect learning, the companies that more quickly obtain the dynamics of creation of more knowledge from already acquired, they raise hardly superable barriers of market by the competitors.
