Applied Motion Study
A Collection Method to industrial Preparedness

MOTION STUDY AND TIME STUDY 71 motion study processes, except the help and ad- vice of a properly qualified observer, or the an- noyance of having one not fitted by training, ex- perience, or natural qualities to co-operate. There is not space in this paper for a discus- sion of the educational features of observations made with these devices, or of their influence upon the new and much needed science of fatigue study, or of their general psychological signifi- cance.1 It is only necessary to emphasise their adaptability, flexibility, and relation to economy. We have here a complete set of inexpensive, light, durable apparatus, adaptable to any type of work and to any type of observer or self-observation. It consists of systematically assembled units that may be so combined as to meet any possible work- ing condition. Through a specially devised method of using the same motion picture film over and over again, up to sixteen times, and through a careful study of electrical equipment and of va- rious types of time spot interrupters, we have been enabled to cut down the cost of making time and motion study, until now the most accurate type of studies, involving no human equation in i See “ Fatigue Study,” Sturgis & Walton, New York.
