therblig

System that divides a task into a number of individual steps. The term was coined by US pioneers of the scientific management movement Frank Gilbreth and Lilian Gilbreth, who invented and refined the system between 1908 and 1924. The origins of the system were the motion studies the Gilbreths carried out on bricklayers.

Therblig is an anagram of Gilbreth. The method is useful for analysing the way a task is carried out to see if it can be performed more efficiently.
