  Therblig - Wikipedia, the free encyclopedia
A therblig is the name for one of a set of fundamental motions required for a worker to perform a manual operation or task.
The Therblig is used in the study of motion economy in the workplace.
A workplace task is analyzed by recording each of the Therblig units for a process, with the results used for optimization of manual labor by eliminating unneeded movements.

 The Gilbreth Network: Therbligs
Therbligs comprise a system for analyzing the motions involved in performing a task.
While the concept of the Therblig was born around 1908, it was constantly being refined and tested, as a tool; a very powerful tool.

The paper focuses on industrial consultants Frank and Lillian Gilbreth, who began photographing and filming industrial workers in 1912 in order to isolate individual movements, which could then be reconfigured to model the "one best way" to perform a given task.

“The ‘therblig’ is the ultimate attempt to turn man into machine: his unique concrete capacities into optimal standard labour.
It is difficult to argue for the variety of modern labour in the face of the ‘therblig.’ In its robotisation of a ten-thousandth of a minute, capitalism shows us its desire to make robots of us all — all of the time.
