Operational Procedure = liu shui; which characters? I hear the term "liu shui" often which means something like business procedure, or procedure (a row of actions).

now I am wondering what the correct characters for this (slang?) term may be.

流水 means "flowing water / business turnover." Is it that?
I just got confirmation from one of my (Chineses) Colleagues that this actually is 流水 (flowing water).
