However, the distinction between the two concepts are not clearly defined. In order to try to clarify the issue seems interesting conceptual problem when it comes to resources, differentiate between it broadly or narrowly. Appeal broadly understood as one means used to achieve a goal set in advance. This definition of appeal also include the concept of capacity, ie, the capabilities of an enterprise will also be resources available to this account. The resources will be strictly defined as stocks of available factors that are owned or controlled by the firm (Amit and Schoemaker, 1993). In contrast, the power capacity would adequately manage the resources to perform a specific task within the company.

Therefore, in this context, capacity refers to the competence of a company to deploy resources, usually in combination, using organizational processes to produce a desired end. In line with the definition of Amit and Schoemaker (1993), Grant (1991) states that the resources (broadly defined) are inputs in the production system and the basic unit of analysis to internal corporate level. The author himself acknowledges that few resources by independent productive, appearing at this level the concept of capacity. A capability is the ability for a team of resources to perform some task or activity. While resources are the source of the company's capabilities, capabilities are the main source of their competitive advantage. But not only limited capacities to organize a coordinated set of resources, but also incorporate capabilities complex interactions between people and between people and other resources that make up the company.
