Manufacture productivity III - quick improvement me-thod of the manufacture productivity: reduction of the inative time and of the process material waiting time

The quick improvement method of the manufacture productivity is based on the reduction or on the elimination of the machine/operator/material inative time, exclusively. The inative time of this three elements is recognized to be main reason of the inefficiency. The method here discussed is specially applicable in the brazilian manufacturing industry (which represents 17% of the PIB). It utilizes five of the most simple, elementary and well-known thechniques and it is applicable in the most frequent situations of the manufacturing industries. The background of the author assures that the method can to improve the productivity beyond 30% in a short time (in a particular enterprise, it was possible to improve 160% the productivity of its machining department). The application of the method and the implementation of its suggested rules are made with right facility and, because that, the results appear very quickly. This paper will detail the reduction in the inativetimes, the reduction in the improductive times and the reduction in the unproductive activities and in productive activities realized in an unproductive form.
