Applied Motion Study
A Collection Method to industrial Preparedness

MOTION MODELS Hl fugal force, inertia, momentum, combination of motions and play for position.1 When there was no such emphasis on speed he was differently af- fected by these variables. 3. While none of the three methods of any in- dividual worker was at all likely to be the stand- ard method, the method used when working rapidly was most likely to approximate the stand- ard. 4. Each teacher had his own short cuts in so far as he bad consciously or unconsciously thought in motion economy. These differed be- cause it was not customary to compare methods, because working conditions sometimes imply trade secrets, and because there was no ade- quate correlation between existing methods, the eye being able to recognise the slow motions only. 5. The best method of doing the work did not at that time exist, because, due to lack of measur- ing methods and devices, it was not possible to record the elements, or motions, of all the differ- ent methods; to measure these, and to synthesize a standard method from the data. i See “ Motion Study,” D.
