but the data from the experiments was so complex and involved that a considerable knowledge of higher mathematics had to be used to apply the data. Furthermore, the data was in such form that it took longer to use the knowledge contained therein than it did to do the work on any given piece of metal cutting. After gathering this knowledge, Dr. Taylor, with his assistants, first Mr. Gantt and finally Mr. Barth, reduced it to such a form that now it can be used in a matter of a few seconds or minutes. This was done by making slide rules.6 Today workers have this knowledge in a form that any machinist can use with a little instruction. As a result, Dr. Taylor's observations have revolutionized the design of metal cutting machinery and the metal cutting industry, and the data Page 079 he collected is used in every metal cutting planning department.
Furthermore, as a by-product to his observations and investigations, he discovered the Taylor-White process of making high speed steel, which revolutionized the steel tool industry. No untrained workman could expect ever to compete with such work as this in obtaining results for most efficient planning and at the same time perform his ordinary work.
Wastefulness of Individual Planning. — Even if it were possible so to arrange the work of every worker that he could be in close proximity to the equipment for planning and could be given the training needed, individual planning for "small lots" with no systematized standardization of planning-results would be an economic waste that would cause an unnecessary hardship on the worker, the employer and the ultimate consumer. Individual planning could not fit the broad scheme of planning, and at best would cause delays and confusion, and make an incentive to plan for the individual self, instead of planning for the greatest good of the greatest number.
Again, even if it were possible to plan best by individual planning, there is a further waste in changing from one kind of work to another. This waste is so great and so obvious that it was noticed and recognized by the earliest manufacturers and economists.
Hardship to the Worker of Individual Planning. — To obtain the most wages and profits there must be the most savings to divide. These cannot be obtained when each man plans for himself (except Page 080 in the home trades), because all large modern operations have the quantity of output dependent upon the amount of blockades, stoppages and interferences caused by dependent sequences. It is not, therefore, possible to obtain the most profit or most wages by individual planning. Planning is a general function, and the only way to obtain the best results is by organized planning, and
