"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."

“The greatest problem before engineers and managers today is the economical utilization of labor. The limiting of output by the workman, and the limiting by the employer of the amount a workman is allowed to earn, are both factors which militate against that harmonious co-operation of employer and employee which is essential to their highest common good.”

“It is becoming perfectly clear that the principles underlying industrial and military efficiency are the same and that a nation, to be efficient in a military sense, must first be efficient industrially”

“Henry Gantt – Management Hall of Fame”

“The aim of our efficiency has not been to produce goods, but to harvest dollars... The production of goods was always secondary to the securing of dollars.”

“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”

“Engineers were the only members of the community "who understand the needs of the nation, desires of the workmen, and the power of the productive forces”
