We are coming to realize more and more that the great test of everything is suitability, and that the mysterious and tangible thing called “suitability” simply consists of the measure of predetermined units of desired qualities. The operating room in the hospital is bare, with plain walls and rounded corners, with the least opportunity for dust lodgment, because that is most suitable to the type of work done there. The modern business desk is flat topped, with no tiny drawers or cubby-holes to collect papers and miscellaneous odds and ends, because this type of desk conforms best with present day systems of office management. In the same way all machinery and office equipment should be without so-called ornament or polish, because in this way the most work can be done with the least amount of fatigue. Our whole idea of ornament is changing. Suitability here also is the standard, and the artists have done noble work in setting an example to the trades. “Suitability” must become a slogan for every department in the organization. [Illustration: FIG. 5 This photograph shows a typical “motion-studied” desk. This desk is cross-sectioned, so that standards can be made as to the placing of those things that are constantly required for work. The only drawer containing any permanent materials is pulled out at the left. It contains duplicate supplies of our standard forms, so arranged that a man will not run out of supplies at his desk, as the holder in which the reserve supply is placed is a notification to the desk supply boy that supplies in addition to the weekly furnishings are wanted immediately.] [Illustration: FIG. 6 This picture shows a “one-motion” pencil rack. This is one of the many little devices that we have used to cause every one throughout the plant to think in terms of elementary and least fatiguing motions. This pencil rack was devised little by little, suggestions coming from different employees. For example, one suggestion was that the grooves be painted different colours, representing the standardized places for the different coloured pencils. Another suggestion was that a deep horizontal groove be added, that the fingers might go around the pencil at the exact place where used when in the position of writing. The slant of the rack is that slant whereby the pencil will surely slide down by gravity to the stop at the bottom of the pencil rack, but not slide with force enough to break even the most delicate point. Such a device alone saves very little time or fatigue, but it represents one of many kinds of devices that make for habits that cause less fatigue.]
