Therbligs:

Therbligs primarily refer to motion of human body at the workplace and to the mental activities associated with it. They permit much more precise and detailed description of the work than any other recording techniques.

Therbligs were suggested by Frank B. Gilberth the founder of motion study who differentiated 17 fundamental hand or hand and eye motions to which an eighteenth has been added.

Each therblig has a specific color, symbol and letter for recording purposes.

Therbligs are used for the following:

  1. In studying the activities of two or more persons on a group work.
  2. In studying the relationship of the activities of the operator and the machine as a means of timing operations.
  3. In obtaining motion time data for time standards.
  4. Acts as a permanent record of the method and time of activities of the operator and the machine.
