The growth of industrial SMEs will be achieved by consolidating product and inventory management systems, reducing costs and improving competitive advantages. This scheme has been called "inventory management". For its development and its contribution to generate competitive advantages, it is necessary to create conditions from the administrative point of view to achieve this purpose. From the operational or administrative process approach, organized companies created as a going concern, depend on a series of external conditions that are part of systems, such as the industry to which they belong to the economic system and society. They receive inputs, transform them and distribute them to their environment, through functions such as: planning, organization, personnel integration, direction and control, which makes them open systems of interaction between the company and its external environment. National and regional economic development can be supported by a productive strategy focused not only on competitive advantages derived from prices, but also on advantages associated with differentiation.
