Abstract :
During the last decade there has grown up in industry a new branch of technology. It has received the appropriate descriptive name of human engineering. The development has come about through an increasing demand for means to assist managers in selecting men better suited, from the points of view of employee and of employer, to the work they have to do. There is wide demand for reliable information about the methods which have appeared in the form of mental tests, trade tests, rating scales, and other means of discovering human qualifications.
