Lean Manufacturing is a philosophy of production that emphasizes the minimization of the amount of all resources used in various activities of the enterprise. It is a systematic approach to identify and eliminate waste through continuous improvement in a manufacturing process. It includes eliminating different wastes, reduced inventory, empowering workers and improved productivity. The term lean was coined by John Krafcik in 1988. It can be traced back to ford, when he first setup his line production for t-model ford. Modern lean manufacturing came into existence by Toyota production system initiatives.
