I think no book is more stimulating than the history of a devoted and successful life. - Frederick Winslow Taylor

The differential rate system of piece-work consists briefly in offering two different rates for the same job: a high price per piece, in case the work is finished in the shortest time possible and in perfect condition, and a low price, if it takes a longer time to do the job, or if there are any imperfections in the work. (The high rate should be such that the workman can earn more per day than is usually paid in similar establishments.) This is directly the opposite of the ordinary plan of piece-work, in which the wages of the workmen are reduced when they increase their productivity.

What I want to try to prove to you and make clear to you is that the principles of scientific management when properly applied, and when a sufficient amount of time has been given to make them really effective, must in all cases produce far large and better results, both for the employer and the employees, than can possibly be obtained under even this very rare type of management which I have been outlining, namely, the management of ‘initiative and incentive’, in which those on the management’s side deliberately give a very large incentive to their workmen, and in return the workmen respond by working to the very best of their ability at all times in the interest of their employers. I want to show you that scientific management is even far better than this rare type of management.

The art of management has been defined, "As knowing exactly what you want men to do, and then seeing that they do it in the best and cheapest way." No concise definition can fully describe an art, but the relations between employers and men form without question the most important part of this art. In considering the subject, therefore, until this part of the problem has been fully discussed, the remainder of the art may be left in the background.
