Time study is the art of recording, analyzing, and synthesizing the time of the elements of any operation, usually a manual operation, but it has also been extended to mental and machinery operations.

Motion Study is a means to permanent and practical waste elimination, — hence a prerequisite to efficient preparedness that shall be adequate, constructive and cumulative.

A better name for scientific management is "measured functional management." It is not sufficient to call it " labor saving 'management " for it deals with more than labor and labor saving. It is a way for obtaining methods of least waste. It not only saves useless labor, but it improves labor conditions; improves quality of product; prolongs the period of the worker's productivity; conserves, teaches and transfers skill and experience. The committee have caused the Society and the world to recognize at last the importance of the feature of the transference of skill, but they apparently still lack appreciation of the even greater feature of the recording and transference of experience of Mr. Taylor's measured functional management and of micro-motion study. Mr. Taylor's system is best described in his writings entitled A Piece Kate System, Shop Management, and On the Art of Cutting Metals, published by the Society, and Principles of Scientific Management, published by Harper & Brothers.
