The Principles of Scientific Management

by Frederick Winslow Taylor

The general steps to be taken in developing a simple law of this class are as follows: First. Find, say, 10 or 15 different men (preferably in as many separate establishments and different parts of the country) who are especially skilful in doing the particular work to be analyzed. Second. Study the exact series of elementary operations or motions which each of these men uses in doing the work which is being investigated, as well as the implements each man uses. Third. Study with a stop-watch the time required to make each of these elementary movements and then select the quickest way of doing each element of the work. Fourth. Eliminate all false movements, slow movements, and useless movements. Fifth. After doing away with all unnecessary movements, collect into one series the quickest and best movements as well as the best implements. This one new method, involving that series of motions which can be made quickest and best, is then substituted in place of the ten or fifteen inferior series which were formerly in use. This best method becomes standard, and remains standard, to be taught first to the teachers (or functional foremen) and by them to every workman in the establishment until it is superseded by a quicker and better series of movements. In this simple way one element after another of the science is developed.
