Lean manufacturing is a production philosophy aimed at eliminating waste. It was pioneered in the 20th century by Toyota through the Toyota Production System. The goals of lean manufacturing are to improve quality, eliminate waste, reduce time, and reduce costs. There are seven types of waste including transport, inventory, motion, waiting, overproduction, over processing, and defects. To achieve a lean system, companies design simple manufacturing processes, recognize room for continuous improvement, and implement the Toyota Production System approach.

"And whenever a workman proposes an
improvement, it should be the policy of the
management to make a careful analysis of the new
method, and if necessary conduct a series of
experiments to determine accurately the relative
merit of the new suggestion and of the old standard.
And whenever the new method is found to be
markedly superior to the old, it should be adopted as
the standard for the whole establishment”
