The Principles of Scientific Management

fundamentals of SCIENTIFIC MANAGEMENT 25 common use for doing the same thing, perhaps forty, fifty, or a hundred ways of doing each act in each trade, and for the same reason there is a great variety in the implements used for each class of work. Now, among the various methods and implements used in each element of each trade there is always one method and one implement which is quicker and better than any of the rest. And this one best method and best implement can only be discovered or developed through a scientific study and analysis of all of the methods and imple- ments in use, together with accurate, minute, motion and time study. This involves the gradual substi- tution of science for rule of thumb throughout the mechanic arts. This paper will show that the underlying phi- losophy of all of the old systems of management in common use makes it imperative that each work- man shall be left with the final responsibility for doing his job practically as he thinks best, with comparatively little help and advice from the management. And it will also show that because of this isolation of workmen, it is in most cases impossible for the men working under these systems to do their work in accordance with the rules and laws of a science or art, even where one exists. The writer asserts as a general principle (and he proposes to give illustrations tending to prove the fact later in this paper) that in almost all of the mechanic arts the science which underlies each act of each workman is so great and amounts to so much
