Strategic Management by Policy (SMBP) that aimed at the integration of strategic planning of business and policy management was developed in the latter half of the 1990's. Seven methods as environmental analysis, product analysis, and marketing analysis etc needed for making reasonable and logical plan of the business strategy were developed in SMBP which are called S7 (Strategic Seven Tools). The strategy factor analysis in S7 is an original and most important method to progress business strategy to policy management. SMBP has been widely utilized to domestic and foreign academic societies and the industrial world now. A further research and development of SMBP like the research of the business model and the business system is expected.
