Word du Jour: Therblig
I learned a new word yesterday: therblig. It’s not a particularly useful term, and originates out of that dodgy human factors business, but here’s a definition:
The fundamental motions of the hands of a worker.These operations are made up of 17 types of motion: search, select, grasp, reach, move, hold, release, position, pre-position, inspect, assemble, disassemble, use, unavoidable delay, avoidable delay, plan, and test to overcome fatigue.Frank Bunker Gilbreth defined these motions in his system of motion study.(Therblig is Gilbreth spelled backwards).
There’s a nifty diagram of 16 therbligs here.

There’s a cool Therblig t-shirt at

It has the therblig designs on the front, in the colors Frank Gilbreth gave them, and a nifty quote about therbligs, from science fiction writer Robert Heinlein, on the back.
