There was used SMED (Single Minute Exchage of Die) for be considering to be a useful tool in the identification of the internal and external factors that concern an effective change. An increase was achieved in the use of machine (decrease of lost time), which the change it realizes in an effective way (decrease of the waste provoked by the take-off) and to support a machine after the change (increase of the productivity).
