Books of Preliminary Data Needed. — In order that this investigation may be best fostered, not only must Page 108 books of standards be published, but also books of preliminary data, which other workers may attack if they desire, and where they can find common elements. Such books of preliminary data are needed on all subjects.>12
Motion Study and Time Study Measure Equipment and Tools.
— Time and motion study are measuring devices for ascertaining relative merits of different kinds of equipment, surroundings and tools. Through them, the exact capacities of equipment or of a tool or machine can be discovered at once, and also the relative value in efficiency. Also motion study and time study determine exactly how a tool or a piece of equipment can best be used.
In "On The Art of Cutting Metals" Dr. Taylor explains the effect of such study on determining the amount of time that tools should be used, the speed at which they should be used, the feed, and so on.13 This paper exemplifies more thoroughly than does anything else ever written the value of Time Study, and the scientific manner in which it is applied.
The Scope of Time and Motion Study Is Unlimited. —
It is a great misfortune that the worker does not understand, as he should, that motion study and time study apply not only to his work, but also to the work of the managers. In order to get results from the start, and paying results, it often happens that the work of the worker is the first to be Page 109 so studied, but when Scientific Management is in full operation, the work of the managers is studied exactly to the same extent, and set down exactly as accurately, as the work of the worker himself. The worker should understand this from the start, that he may become ready and willing to coöperate.
Detailed Records Necessary. — Motion study and time study records must go
