Therefore, until the workers can be taken to see the fatigue eliminating devices in actual operation, collect such devices, or photographs of them, and put them all in one place. Start a little fatigue museum of your own, even if it is limited to a properly labelled scrap-book of pictures always ready for inspection, and observe the effect upon management, workers, and invention in general. This effect will be reflected in the suggestion box, which in itself provides a unit of measurement of the progress of the fatigue eliminating campaign. When fatigue elimination has progressed to this stage, when actual devices are being installed, when the entire organization has come, as it will, to think in terms of fatigue elimination, the problem may be attacked scientifically. This, the scientific elimination of unnecessary fatigue, is the subject for discussion in the next chapters. Summary. A fatigue museum is a collection of devices for eliminating or overcoming fatigue. The parent museum in Providence aims to exhibit such devices as object lessons, and to encourage the spread of fatigue study by sending photographs with descriptions to all who are interested enough to start museums or even a scrap-book for pictures of devices for the elimination of unnecessary fatigue in the industries. Our fatigue museum specializes on chairs, but welcomes devices of any kind. It advocates the establishment of similar museums in colleges, or other institutions, and also in industrial plants and work places of all kinds. CHAPTER VII FATIGUE MEASUREMENT AND FATIGUE ELIMINATION: HOW TO ATTACK THE PROBLEM SCIENTIFICALLY History of Fatigue Measurement. Accurate fatigue measurement is in its infancy as applied to the industries. Such measurement can take place only where there is complete co-operation between the man measured and the man making the measurements. With the co-operation, that is the natural result of measured functional management, comes the possibility of making accurate measurements of fatigue under either laboratory or shop conditions. It is as easy to pretend to be tired as to pretend to be working. There is little or no profit in measuring pretended states. Under the scientific form of management there is no incentive to pretend anything. The incentive is, rather, to show exactly what one is doing and how one feels, in order that accurate records may be made, and that the offered rewards may be received. We have, then, at this stage, where every member of the organization realizes that co-operation is necessary for the good of all, the opportunity to measure fatigue with considerable accuracy.
