As it can be seen from the definition of Raven, capabilities will also be within the reach of the company’s organisational, resources that will energize the rest of resources that owns a business organization. However, other authors consider by resources, inter alia, to human skills and the organizational routines that for others is clearly a capability. For its part, Barney (1991) and Grant (1991) recognize the existence of organizational resources, which shall not be more than a concept very similar to the capacity. As it can be seen from the above, the debate about these concepts is not yet closed. However in this study will be the trend for the broad sense of the term resource.

Another point that emerges of importance in this work is the distinction between resources and distinctive competences. For this clarification, the reflection is needed on the traditional concept of sustainable competitive advantage (Coyne, 1986). The resource-based approach identifies resources as a source of competitive advantages. But it is not enough to have a competitive advantage, this must also be sustainable in time and company should be able to appropriating income generated. The competitiveness of the company then depends on its ability to set up a portfolio of unique resources, which confer a series of distinctive competences. Selznick (1957), refers to the concept of distinctive competence of an organization, not as what you can do, but what you can do well. Andrews (1971) for its part already gives you a current conception to refer to the experience in producing and marketing a line of products, development of capacities of individuals comprising the Organization, the degree in which the individual capacity applies to the common task, and the quality of individual effort and Group coordination. Other authors define the competences of the Organization as the level and patterns of deployment of resources and past and present abilities that help the organization achieve its goals and objectives, to differentiate them from resources is obtained and resources deployed so that they can not be easily duplicated by others.
