Applied Motion Study
A Collection Method to industrial Preparedness

UNITS, METHODS AND DEVICES 35 to time-study in that it determines what path a motion is to follow, while time-study determines how swiftly the path is to be traversed and the amount of rest required to overcome resulting fatigue. The two measure work and determine the best method by which the work can be done. Motion-study, time-study, micromotion-study, fatigue-study, and cost-study are important meas- ures of scientific management, by which the effi- ciency of each function and subfunction is deter- mined, tested, and checked. The unit to be chosen for intensive study is determined by the amount of time and money that it is possible to save by the investigation. This unit is deter- mined by the following method. The work se- lected is divided into natural subdivisions or cycles of performance. Each cycle is then sub- jected to motion study, to determine the best method to use in performing the work. This method is divided into the smallest practicable units. These units are timed. The timed units are then again subjected to motion study, for more intensive study of method. Subdivided mo- tions result. These are again timed, and so the process proceeds until the further possible saving
