ABSTRACT
The “human factor” is a phrase much used in discussion to-day and it is for several reasons convenient to our purposes. The phrase supplements the fact of man-power given in the first chapter, and applies only after the number and kind of workers is determined. The “human factor’” could not be said to be increased by the mere addition of more men, and refers essentially to variations in efficiency per man. Once the total man-power is known, the question now is, how can the power of each man be increased?
