Lean thinking
  Market competition in the United States suffered the failure of the automotive industry, has experienced twists and turns in the process of understanding, finally realized that the result of its competition is the key to the failure of U.S. auto manufacturing industry lost to mass production methods of Toyota's lean production methods. In 1985, MIT Professor Daniel T. Jones and other financing for five million U.S. dollars, with nearly 5 to 90 years more than a comparative analysis of automobile plant in 1992 published a 'machine to change the world,' a book, Toyota Production System to be known as lean production and its management and content of thinking characteristic of a detailed description. Four years later, the author of the book the publication of its sequel, 'lean thinking', and further from the theoretical into the lean production that are included in the new management thinking and lean manufacturing methods other than extended to all fields, especially in the tertiary industry, the extension of lean production methods to all aspects of business activities, is no longer confined to areas of production, thereby encouraging managers to rethink the business process, eliminating waste and creating value.
  Lean thinking is the core of the investment less and less - less human, less equipment, a shorter period of time and space to create a smaller value of as much as possible; at the same time getting closer and closer to users, they really want. Precise definition of value is a critical first step in lean thinking; to determine each product (or, in some cases to determine each product line) the full value of flow is the second step of Lean thinking; then is to retain down the various steps to create the value of the flow, so that the need for completing a number of days to process orders, completed in a matter of hours, so that the completion of the traditional production of goods from a few months or weeks down to days or a few minutes ; then we should in time to keep up with changing customer needs, because once users have a genuine need in the time will be able to design and arrange production and to create products that users really need the capacity, it means that can give up their sales, direct according to user requirements to inform the actual production, that is to say, can be driven by user needs, rather than the users do not want to push the product hard to the user.
  Lean thinking, including lean production, lean management, lean design and lean supply a range of ideas, the core of which is through 'appropriate and timely', 'zero inventory', 'summons card' means, such as site management, 'ordering the production of ', so as to ensure product quality and lower costs. Lean thinking was reflected in the quality control of products, meaning products are not the pursuit of cost advantage and technology leadership, but stressed that the cost of the product and technology matching, coordination. Since then, the business will be gradually extended lean thinking, business activities extended to the whole process, that is, the pursuit of business investment and maximize the economic output, to maximize the value. From the literal meaning of 'spirit' embodied in the quality, the pursuit of 'perfect', 'excellence'; 'benefit' in the cost, only cost the average cost below the industry can benefit businesses. Thus, the pursuit of lean thinking is not simply the lowest cost, the quality of the eyes of the best companies, but the pursuit of satisfaction of users and businesses have the quality, cost and quality of the pursuit of the best configuration, the pursuit of the optimal price performance ratio.
Definition
  Lean production is an enterprise in order to minimize the space occupied by the production of resources and reduce the cost of enterprise management and operation of the main objectives for the production, at the same time it is a philosophy, a culture. The implementation of lean production is the determination of the course of striving for perfection, but also the process of the pursuit of excellence, which is supporting the individual and the enterprise of a spiritual force of life, but also in the never-ending learning process to obtain a level of self-satisfaction. The goal is to strive for excellence, perfect, never-ending quest of the ultimate goal of seven zeros.
Substance
  The essence of lean production management process, including the optimization of organization and management personnel, middle management efforts to streamline, flat organizational reforms to reduce the production of non-direct staff; push for a balanced production of synchronization to achieve zero inventory and flexible production; the implementation of the entire production process (including the entire supply chain) of the quality assurance system, and achieve zero non-performing; reduce and reduce any areas of waste, zero waste; pull the eventual realization of just-in-time production.
The ultimate goal
  'Zero waste' as the ultimate goal of lean production, specifically manifested in seven PICQMDS, the goal in detail as follows:
  (1) 'Zero' approach to changing products a waste of time (Products? More productive varieties)
  Processes of species will change with the assembly line of converting a waste of time to 'zero' or close to 'zero.'
  (2) 'Zero' inventory (Inventory? Abatement Stock)
  Processing and assembly will be connected to water, and the elimination of intermediate inventories, estimated production for the market change orders synchronous production, zero inventory of products.
  (3) 'Zero' waste (Cost? Comprehensive cost control)
  The elimination of redundant manufacturing, transportation, waiting for the waste, zero waste.
  (4) 'Zero' bad (Quality? High quality)
  Not bad check-bit detection and the source should be the elimination of it, the pursuit of zero non-performing.
  (5) 'Zero' Fault (Maintenance? Improve the operation rate)
Machinery and equipment to eliminate downtime, zero failures.
  (6) 'Zero' stagnation (Delivery? Rapid response, short delivery)
  Compression to maximize the lead time (Lead time). To this end to eliminate the middle of stagnation, the realization of 'zero' stagnation.
  (7) 'Zero' disasters (Safety? Safety first)
  People, factories, product safety precautions comprehensive inspection, the implementation of SF inspection system.
