Applied Motion Study
A Collection Method to industrial Preparedness

MOTION MODELS 109 facts. We say “ facts ” advisedly, for the motion models have proved them to be such. We use the word with exultation, for, while we believed them to be facts for years, because the results justified the theories, we have often been ridi- culed by students and investigators in all lines for so believing. Only since the motion models demonstrated the facts are they coming to be ac- knowledged as such, and are we receiving assist- ance in making them more generally useful. The facts are as follows: 1. The motions are the elements to be consid- ered in learning to perform an activity. 2. Right motions must be insisted upon from the beginner’s first day at work. 3. Right motions do not lie in the consecutive acts of any one person performing the activity, unless he has been specially taught the standard method. 4. Fast motions are different from slow mo- tions. 5. Standard speed of motions must be insisted upon from the learner’s beginning on his first day, if least waste of learning is the first considera- tion.
