Motion Study
A Method for Increasing the Efficiency of the Workman

82 MOTION STUDY It is impossible to determine whether or not a motion is absolutely necessary until the method of doing the work in which it is used is standard. Examples. — i. Motions which were relatively proved necessary in laying brick by the pick-and-dip ” method or “ stringing-mortar ” method, the brick being lifted from the stock platform, became absolutely unnecessary when the ‘‘packet-on-the-wall” method of handling brick was adopted. 2. The same thing is true of motions eliminated by handling mortar in a fountain trowel. The final solution of the problem of necessity of motions will be discussed later, though the subject is so large that no amount of discussion could do more than touch it. Path The determination of the path which, will result in the greatest economy of motion and the greatest increase of output is a subject for the closest investigation and the most scientific determination. Not until data are accu- mulated by trained observers can standard paths be adopted. The laws underlying physics, physiology, and psychology must be considered and followed. In the meantime, merely applying the results of observation will reduce motions and costs and increase output to an amazing degree. The path most desirable is usually that which permits gravitation to assist in carrying the material to place.
