"For continuous flow production such as this I know of nothing better for recording output and comparing performance with capacity or what ought to be produced, than the straight line charts developed by Mr. H. L. Gantt, which show required and actual production in terms of both quantity and time. Their use, however, is not limited to the class of work just described."
Henry Laurence Gantt was an American mechanical engineer and management consultant who worked in the development of scientific management. He created the Gantt chart in the 1910s.
"The mechanical engineer today is carrying forward, under the direction of science, the work that was begun by the mechanic who first learned to chip flint or make a fire ; and it is he alone that can lead the mechanic of today to a better understanding of his problems, and the capitalist to a better appreciation of their solution."
"Scientific investigation is rapidly putting at our disposal vast amounts of knowledge concerning materials and forces, which it is the business of the engineer to utilize for the benefit of the community. Well-designed plants and efficiency labor-saving devices, to be seen on every hand, bear testimony that he is doing at least a portion of his work well. When, however, it comes to the operation of these plants and the utilization of these labor-saving devices, the lack of co-operation between employer and employee, and the inefficient utilization of labor, very much impair their efficiency. The increase of this efficiency is essentially the problem of the manager, and the amount to which it can be increased by proper study is, in most cases, so great as to be almost incredible."
"Whatever we do must be in accord with human nature. We cannot drive people; we must direct their development... The general policy of the past has been to drive, but the era of force must give way to that of knowledge, and the policy of the future will be to teach and to lead, to the advantage of all concerned"
"For more than twenty years Mr. Gantt has been closely interested in advanced work in the field of labor management. For more than ten years his name has been identified with certain methods which, nevertheless, are yet but partially and imperfectly understood by many, and because of this incomplete understanding are sometimes supposed to be summed up in the "Bonus System" of wage payment."
"Finance and industry must be socialized somehow. If we refuse to do it from the bottom we shall have to do it from the top, and doing it from the top means the emergence of many Prussias — with wars upon wars."
"There is another and higher leadership, that of the intellect, by which the methods and thoughts of one man may affect the whole civilized world. Industrial leaders who have most prominently attracted our attention in the past are those who have, by their inventions or their direction of activities, accumulated large fortunes ; but none of these are as great as the man who by the force of his intellect leads people throughout the civilized world to benefit themselves and others. Such a man was the late Frederick Winslow Taylor who, in his determination to eliminate error and to base our industrial relations on fact, set an example which will have an effect all over the world"
