Taylor’s friend Henry Gantt explains to his fellow engineers in the middle of the First World War that they must "develop a task system on the basis … - Henry Gantt

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.

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.
