FRANK AND LILLIAN GILBRETH 

Frank and Lillian Gilbreth were associates of Fedrick Winslow Taylor. The Gilbreths, unlike Taylor, had experience in unionised industry, which presumably limited their enthusisasm for timing jobs. They were one of the great husband-and-wife teams of science and engineering. Frank and Lillian Gilbreth early in the 1900s collaborated on the development of motion study as an engineering and management method. Some of their significant ideas on management are given below:

1.  They held the most significant cause of workers and emphasized that the management should understand their needs and personality.

2.  The system became known as "speed work" and the speed came not from rushing the workers to work faster, but by cutting down needless actions.

3.  He identified the 18 on-the-job motions known as "THERBLIGS".
