Motion Study
A Method for Increasing the Efficiency of the Workman

52 MOTION STUDY question of fatigue of the worker. The best lighting con- ditions will reduce the percentage of time required for rest for overcoming fatigue. The difference between the cost of the best lighting and the poorest is nothing com- pared with the saving in money due to decreased time for rest period due to less fatigued eyes. It is a similar case to the taxicab concerns — they charge their drivers with gasoline and tires and mileage, accidents, etc., but they furnish the lubricating oil free. The fallacy of the common practice of putting the lighting in the hands of the man whose merit is measured inversely as the coal bill is obvious. The sub-variables involved make the problem as to exactly what lighting is most desirable difficult of solution. The proper solution will have such a beneficial effect, not only upon the man’s work, but also upon his welfare, that no time or effort expended upon it can be too great. Quality of Material It is essential to the use of standard motions and the resulting large output that all material used shall be in exactly that state in which it can be most easily handled by the worker. Examples. —-1. If there are lumps in the mortar, due to pieces of brick or shavings or lumps of lime, or cement or coarse pebbles in the sand, it is impossible for the bricklayer to do his best work. 2. If the sand is not selected with reference to the thick-
