It takes into accounts reflections from recognized authors, which apply equally to industrial and service companies, as well as some experiences of the author. The conclusion makes special emphasis that approach to analyze the issue of costs, and the role that assume the people who make this approach from the areas of production, sales and administration of companies, not only must be adapted to the reality of the current scenario of global and digital competence, but to question the paradigms that were given by certain by some authors just a few decades ago.
