Lillian Gilbreth

"The things which concerned him more than anything else were the what and the why--the what because he felt it was necessary to know absolutely what you were questioning and what you were doing or what concerned you, and then the why, the depth type of thinking which showed you the reason for doing the thing and would perhaps indicate clearly whether you should maintain what was being done or should change what was being done."

"Psychology of Management, as here used, means, the effect of the mind that is directing work upon that work which is directed, and the effect of this undirected and directed work upon the mind of the worker."

"... what is there in the subject of psychology to demand the attention of the manager?"

"Of what value is the study of management?"

"Management practitioners today largely ignore Frank and Lillian Gilbreth, possibly because the principles of motion study they pioneered are now very unfashionable. Motion study entailed the detailed examination of the movements individual workers made in the process of carrying out their work. It was, however, just one of the concepts the Gilbreths developed. Through Frank's concerns that the efficiency of employees should be balanced by an economy of effort and a minimisation of stress, and Lillian's interest in the psychology of management, their work laid the foundations for the development of the modern concepts of job simplification, meaningful work standards and incentive wage plans."

"One of the undesirable by-products of the factory system was the frequent abuse of unskilled workers, including children, who were often subjected to unhealthy working conditions, long hours, and low pay. The appalling conditions spurred a national anti-factory campaign. Led by Mary Parker Follett and Lillian Gilbreth, the campaign gave rise to the “human relations movement" advocating more humane working. Among other things, the human relations movement provided a more complex and realistic understanding of workers as people, instead of merely cogs in a factory machine."
