The concept of Lean Production derives from Toyota Production System which was an outgrowth regulated by thepost WWII Japanese automobile market characterized as “resource scarcity” and “products of big variety but small quantity”. Essentially, Leanis centered on economic efficiency, or in another word improving overall customer value by reduced waste, enhanced speed and better quality.

①Over production
②Over processing
