Design for lean manufacturing  Design for lean manufacturing is a process for applying lean concepts to the design phase of a system, such as a complex product or process. The term describes methods of design in lean manufacturing companies as part of the study of Japanese industry by the Massachusetts Institute of Technology. At the time of the study, the Japanese automakers were outperforming the American counterparts in speed, resources used in design, and design quality. Conventional mass-production design focuses primarily on product functions and manufacturing costs; however, design for lean manufacturing systematically widens the design equation to include all factors that will determine a product's success across its entire value stream and life-cycle. One goal is to reduce waste and maximize value, and other goals include improving the quality of the design and the reducing the time to achieve the final solution. The method has been used in architecture, healthcare, product development, processes design, information technology systems, and even to create lean business models. It relies on the definition and optimization of values coupled with the prevention of wastes before they enter the system. Design for lean manufacturing is system design. Not to be confused with "Lean Design" (copyrighted and patented by Munro & Associates, of Michigan), design for lean manufacturing builds on the set of principles that emerged from design for the customer value and design for manufacturability. Since some lean tools are used in the practice of design for lean manufacturing, it borrows the first word in its name from lean manufacturing as exemplified by the Toyota Production System. Design for lean manufacturing was first coined by Womack, Jones, and Roos after studying the differences between conventional development at American automotive companies and lean methods at Japanese automobile producers. While lean manufacturing focuses on optimization of the production stream and removal of wastes (commonly referred to as muda, mura, and muri) once the value stream has been created, Lean Design ® (Munro & Associates) concerns itself with methods and techniques to create a lean solution from the start, resulting in more value and fewer wastes across the value stream. Lean design ® seeks to optimize the development process through rapid learning cycles to build and test multiple concepts early. Managing the knowledge value stream, systematic problem solving with analysis of the trade-offs between various design options, and solutions generated from ideas filtered by systematic innovation methods are viewed as methods within the lean design process. Design for lean manufacturing is based on the premise that product and process design is an ongoing activity and not a one-time activity; therefore design for lean manufacturing should be viewed as a long term strategy for an organization.
