In view of the competitive scenario in which organizations are currently inserted, it is necessary for them to adopt a philosophy of continuous learning, aiming at improving their products and processes, besides encouraging an environment that allows knowledge exchange and innovation. On the one hand CNOs aim at increasing competitiveness through the flow of knowledge aggregated to products and processes in a formal environment.
