Lean

A five-principle system — specify value, map the value stream, create flow, establish pull, pursue perfection — to do more with less while giving customers exactly what they want.

A production philosophy built on absolute elimination of waste, resting on two pillars: just-in-time and autonomation (jidoka).

Coined 'lean' to describe production systems using less of everything — less inventory, space, effort and time — compared with mass production.
