The quick improvement method of manufacture productivity is exclusively based on the reduction or elimination of the machine/operator/material inactive time. The inactive time of these three elements is recognized to be the main reason for inefficiency. The method here discussed is especially applicable to Brazilian manufacturing industry (which represents 17% of the GDP). It utilizes five of the most simple, elementary and well-known techniques and it is applicable to the most frequent situations of the manufacturing industries. The background of the author assures that the method can improve productivity by more than 30% in a short time (in one particular enterprise, it was possible to improve by 160% the productivity of its machining department). The application of the method and the implementation of its suggested rules are made with great ease and, because of that, the results appear very quickly. The paper will datail the reduction in machine wait-time during the inspections, as well as the reduction in operator wait-time.
