Applied Motion Study
A Collection Method to industrial Preparedness

MOTION MODELS 127 teach the expert and to teach the beginner. The expert uses the motion model for learning the existing motion path and the possible lines for improvement. He notes the indications of an efficient motion, its smoothness, its grace, its strong marks of habit, its indication of decision and of lack of fatigue. Nothing but a close study of an efficient motion, as compared with the vari- ous stages of inefficiency through which it passed, can make clear these various indications. The changes from awkwardness to grace, from inde- cision or hesitation to decision, from imperfect habit to perfect habit, have a fascination to those interested which seems to increase constantly. The expert, then, takes the model in whatever stage it may be, and through its use charts the lines along which the progress towards a more efficient path can be obtained. The motion model is to the expert a “thought detonator,” or a stimulus to invention. On the other hand, to the beginner who is a learner, the motion model is a completed thing, a standard, and it should be in the most perfect state possible before being given to him. Through its use he can see what he is to do, learn about it through his eye, follow
