16885J/ESD35J-NoV18,2003 Systems Engineering and Lean Thinking Systems Engineering grew out of the space industry in response to the need to deliver technically complex systems that worked flawlessly upon first use se has emphasized technical performance and risk management of complex systems. Lean Thinking grew out of the Japanese automobile industry in response to the need to deliver quality products with minimum use of resources Lean has emphasized waste minimization and filexibility in the production of high quality affordable products with short development and production lead times Both processes evolved over time with the common goal of delivering product or system lifecycle value to the customer
