To expand the Quality management as competitive system for small and medium enterprises, model which is particular and different from that of big enterprise should be designed only for them. We did a survey study to construct a suitable management model to implement the six sigma for small and medium enterprises. As a result of survey and other companies` cases, We designed special model for small and medium enterprises. As the result of this research is the model based on national capital region companies, companies trying to develop six sigma should adjust it for each own company. We hope this research will play an important role to help small and medium enterprises in difficulties.
