The Toyota Production System (TPS) was initially developed from studying Fordâ€™s Production System in the 1920s. Originally known as lean manufacturing, lean systems is an area of study showing that both productivity and quality can improve when manufacturing products while eliminating waste and improving work methods. Not surprisingly, most industrial companiesÂ want to eliminate waste, improve quality and lower cost. Not limited to manufacturing, lean has proven to be applicable to any industrial operation because even though it originated on the shop floor while producing and manufacturing products, it relates to labor psychology and industrial engineering. A majority of companies are very successful applying industrial engineering to make processes more effective and efficient. Lean systems enhances these results by motivating and equiping employees to use similar techniques to improve their work processes.
