Small and medium enterprises have played an important role in Taiwanese economic development. However, there are few studies talking about their history of initiating entrepreneurship and systematic developments. Therefore, this paper adopts case study method, using qualitative research method to collect and analyze data. We take one medium and public company in Taiwan to study and interview 26 people semi-structurally from the case company. The targets we interviewed include chairman, vice-president, supervisors, stockholders ; others are senior managers and ex-senior managers. This paper made a systematic analysis on the entrepreneurial and development progress. Based on the way of stories-telling, we intend to find out different practices of the case company from the same trade; discuss starting business, operation characteristics, and leadership styles in order to argue its actual construction.
