Actually, the industrial engineering has contributed a lot in establishing industrial and organizational psychology as a discipline. Mr. Frederick Winslow Taylor and Mrs. Lillian Evelyn Gilbreth are one among pioneer whose contributions are greater then any psychologist.
Taylorism broke down the components of manual work in manufacturing environments, measuring movement (hence Gantt charts and the "time-and-motion" studies of Frank and Lillian Gilbreths) so there might be a proven best way to perform each task. Scientific management was (and continues to be) used to increase productivity and efficiency; however, it discounts the human aspects of employment (for both individuals and groups). Whereas quantitative methods and engineering theorists had been concerned with structure and the mechanics of organizations, the theorists of human relations and behavioral sciences in the Hawthorne Studies focused on motivation and leadership; assumptions about the relationship between employers and employees were at the center of their thinking. However, from the 1950s, doubt was increasingly cast on the applicability of the Hawthorne Studies to everyday working life.
