It analyzed in the environment manufacter the execution of the tasks of each laborer, its movements and processes of work, perfecting them and rationalizing them gradual. As the period of Taylor was marked by its book Principles of the Scientific Administration (1911) that it concluded that the rationalization of the laboring work would have to be folloied of a general estruturao of the company who had to make use of a compatible architecture eats rationalization of the times and movements. Taylor assured that the industries of its time suffered of 03 (three) males: the systematic vagrancy of the laborers who reduced the production to keep its wages; the unfamiliarity on the part of the management of the routines of work and the necessary time for its accomplishment; the lack of uniformity of the techniques or methods of work. Identified these factors of risk, it created a system based on the intensification of the rhythm of work in search of the enterprise efficiency. The knowledge of Taylor if had perpetuated through the times for having carried through a complete analysis of the work, its times and movements, necessary standards of execution, specialization of laborers and of the direction and installation of a planning room. The useless movements were discarded whereas the useful ones were simplified, rationalized or casting. With use of the chronometer it can evaluate the time expense in the accomplishment of each movement, that added to the exit and open assembly times of the laborer of the production line to take care of its personal necessities, resulted in the call & ldquo; time padro& rdquo;. It was materialize theory of Adam Smith when times before, praised that: Amongst males of the routine, it would have the division of the work without the control of the work for the worker – these are the essential ingredients of the marxist analysis of the time transformed into product.
