Lean Manufacturing Ten Common Misunderstandings 1, lean = high-volume production. In Taiichi Ohno site management book written, he thought the Toyota Production System is ideal for small batch production, and not necessarily for the Toyota had to move towards mass production. Described in Chapter 20 to reduce the conversion time by Toyota to keep the number of lower volume, Taiichi Ohno said: Review We have just begun to explore the Toyota production system, when demand is about 3,000 to 5,000 vehicles per month, and need to produce many different varieties. This is not completely the so-called multi-variety and small quantities, although some small quantities, exactly is the middle volume. Therefore, for medium-sized companies, Toyota production system running nice. Toyota production system born out of the monthly production from 2000 to 3000 period, when production reached such a high number of Toyota now, you may not need to use the system to reduce the cost. Taiichi Ohno&#39;s book, subtitled &quot;Toyota Production System: Beyond large-scale production&quot;, Japanese for &quot;off the scale and Commerce の を し て Circular za&quot;, could be better translated as &quot;no size restrictions management&quot; or &quot;jump on the scale of management style. &quot; Taiichi Ohno clear that the Toyota production system is based on the size or number of out of production. 2, the Japanese company that is lean. Japanese people will not naturally lean production, the Japanese are not inherently lean than other countries to do better. As more Americans are not inherently good at heart surgery, or even the whole world is concerned about the U.S. world-class cardiac surgery, both of which are formed by historical reasons. Japanese companies like the long-term point of the plan, lifetime employment system are favorable to promote staff development. So you can be sure, many Japanese companies have a good foundation to support Lean. But if most or many Japanese companies Toyota-based approach, actively construct and improve its operating model, it is inaccurate. 3, just like a series of tools for lean production. Lean did have a series of powerful tools, including problem identification, root cause analysis and problem resolution. However, the Toyota Production System = lean production, which is how to solve the problem where TPS is the most important part. 4, using only pure lean production for lower costs. People to higher targets for improvement, needs to go beyond what the company is good, toward what the family, social and environmental benefits of the state. In the short term people may ask, &quot;What can I learn?&quot; But it is also a long-term problem. Reduce costs, are nothing new. Lean production is about as easy to work and reduce obstacles to work, so that working time can be put on what is important, entertain clients and personal growth. The decline in the cost of subsequent results. 5, assembly line, work unit, work team = lean production. These three variables of different ways. The main difference is recognized that some personnel, materials and facilities is a combination of lean production. Create a work unit and team may be lean, but understand the idea behind the more important, not just the physical or organizational configuration. Such things often encountered in such an organization - have done a few months or years of lean, but it works and does not imagined so well. So that &quot;we may not the same as other companies,&quot; the idea will become a stumbling block for the implementation of Lean. 6, Lean = identify the product value, value stream mapping, flow, pull, perfection. Lean Enterprise Institute to promote the popularity of Lean, this definition is not wrong, just too much simplified, and thus ignored in many aspects. Stressed the value stream, flow, and pull a bit redundant, as they are to the overall optimization. While this is important, but only the Toyota Production System one of the pillars (JIT), which is another important pillar of self 働. Perfect not only defined by an atheist is inconceivable, and that is to improve the end. There exists a perfect addition to the thing? There will be an ideal state, because by the definition, this is the best we humans can imagine the state. And we continue to study, and there may be more ideal state can exist. 7, Lean is the latest management fashion. Perhaps half of them are misunderstood. Lean is a management fashion, of course, and with the universal and tend to lean recession or at least evolved into a new, improved definition. As the term &quot;lean&quot; must be replaced by a more appropriate term, so that people can better understand what factors have led companies such as Toyota becomes remarkable. But do not lean over the previous half-century invention of the scientific method and the desire for a harmonious society more innovative way. 8, Lean is eliminating waste. Lean is about eliminating waste most. And also to eliminate variation and overload. Variation will lead to overload, resulting in waste. Elimination of waste is out of variance (including changes in customer demand, staff capacity different quality of materials, etc.) caused by overload (to force the system to do things non-design) of the root causes in order to establish more robust systems. For most of us who lean journey in the early stage of focusing on eliminating waste more easily, while exploring wasteful of system-level reasons. 9, Lean does not like computers and IT solutions. Lean does not discriminate against any respect for people and technology to help eliminate waste. Lean the core value is called in Japanese genchi genbutsu (now to the current object), in English known as the &quot;go see&quot;. Especially in management and problem solving should be the spirit of &quot;things are in now,&quot; the principles are based on the fact that the scene to complete. Software solution is easy to make smart people out of theory with the reality of the scene (product contact customers). With a huge LCD screen visual effects on the plant is very impact of visitors, but the white board and staff actually easier to use, to record five minutes before the actual problems that occurred. 10, Lean + your favorite business vocabulary = good idea! I think that only the largest and most optimistic of consulting firms and manufacturing software solutions will still have to do so, but occasionally there are accidents, like the lean outsourcing, begins to create a miracle no matter how Ye Yao. Perhaps there is a huge lean + YFBH consulting market, but advocates like us really miss TPS. ?
