Applied Motion Study
A Collection Method to industrial Preparedness

174 APPLIED MOTION STUDY has an unscientifically constructed back. We re- plied to him that, in most cases, we are so glad to get any chair at all, and so delighted when we have a chair whose height is prescribed by accu- rate measurement that we have been unwilling to dampen the enthusiasm of our co-operators by criticising the backs severely. Physiologists and psychologists must co-operate in the work of solv- ing the fatigue problem. However, we feel that Tve have accurate methods of measurement to put at their disposal, and that the derivation of the necessary data for ideal fatigue eliminating and recovery providing devices must be a matter of time and careful application only. What does Scientific Management do about fatigue in prac- tice? It eliminates all unnecessary fatigue that it can discover. It provides the rest intervals according to the best information available, and at the most scientifically determined intervals at hand. It also provides means for making these rest intervals efficient and profitable. We turn now to the question of monotony. What do we mean by saying that work is monot- onous? In the ordinary use of the term, un- doubtedly, that it is tiresome, that it has same-
