The concept of the team identity transformation in entrepreneurial process was addressed in this thesis. In order to effectively and delicately descript the formation and transformation process of the team identity, Qualitative research and single case method were explored that an electronic component manufacturer (thereafter called F company) in Kaohsiung was chosen. I collect the first-hand data not only by interviewing with interviewees but emailing or talking via phone. In aspects of interview, formal interviews took 17hours, informal interviews took about 10hours and 2 hours was used to get data via telephone communication. Except for first-hand data, we collect the secondary data as well. With comparison on differences of technological team identity(ies) between in and after business creation, three categories grounded on interviews was developed, including think¡Bwork and learn. Based on these, we would try to analyze the reasons of transformation. After almost year of observation and data collection, I conclude these below: 1¡BThere is existence of technological team identity in initial stage of entrepreneurship and this will be beneficial to drive the entrepreneurship. The mechanism of formation is how to pick up the members to make them highly consistent in thinking and behaviors. 2¡BAs changes of contexts and self adaptation, the technological team identity would be transformed as the figure6.1 shown. 3¡BI found that the team identity would transform into organizational identity, and that would make the border between technological team and the other groups more and more unspecific. 4¡BIn the process of team transformation, managerial action and machismo play an important roles to harness how the process goes to make the organization more flexible and actively response to the complex environments.
