| Lean production is a type of production method advocated by Ford beside mass production. Lean production completely overthrows mass production in terms of thoughts.Its goal is to deliver the appropriate product to the appropriate destination in the shortest time; at the same time, to waste as least as possible and adjust to the market environment. Compared to abuses such as long delivery time, frequent changes of plans, lean production not only can reduce wasting and also improve product quality and circulation. Since the 1980's after many scholars study, lead production has become the hot spot of production method. During 1990's, Porsche suffered huge loss, but overcame its hardship by implementing lean production, and became one of the most profitable companies. In US, other companies such as Harvey Davidson, Boeing also became profitable due to implementing lean production. Many domestic auto companies also try to implement lean production. Other companies such as Ji-Nan Steel and Chin Dou Beer are implementing lean production internally.Most companies only saw the effect of lean production on surface. For example, we have TAKT, Kanban and andon production systems. If the companies only depend on those systems above to carry out their lean production method, it will soon meet limitation. There is organization culture beneath the operation system. Companies must confirm what kind of culture exists in them. Then, it must identify whether it is a advantage or disadvantage for the company. The company must identify them in order to converge its culture and the culture to promote lean production.When understanding company culture, there are two schools:qualitative analysis and quantitative analysis. Qualitative analysis advocates real time observation, survey, and systematic study.By interpreting artifacts out of organization culture, digging espoused values and norms, verifying basic underlying assumptions of organization culture, the company can find its root of culture. However, it is hard to measure objectively when using qualitative analysis. When discussing organization culture, it is hard to do comparable study.Quantitative analysis proponents advocate studying organization culture through Characteristic and dimensions. Quantitative analysis and model analysis both play main roles in analytical studies in western world. According to western management theories, human behavior can be analyzed by quantitative method. These scholars think quantitative testing method is the right way to study organization culture.Using quantitative analysis exists a problem. Deviation will happen due to difference in the understanding of survey. However, Qualitative analysis will also have different results due to different interpretation of culture in which it leads to different assumptions of culture base. Using organization observation and quantitative analysis can standardize the measurement of organization culture and strengthen culture ties.Recently, the cross usage of qualitative analysis and quantitative analysis which delivers excellent company culture measurement has become the common acknowledgement among scholars and firms.By applying lean production theory, this study use lead production case studies to illustrate organization culture factors to build up its framework. At last, the study uses real life cases to promote lean production methods to measure the relationship between company cultures and company operation efficiency.According to case studies, Denison organization cultural structure(DOCS)'s 12 factors plus another independent factor can analyze company culture's effect on lead production. Companies can understand their culture's impact through survey before using lean production. Then the companies can change their culture to benefit the implemention of lean production. During the process, they can also make sure whether the companies'cultures have become their employees' core value. The management and external experts should confirm the basic assumptions of companies'culture. |
