In the era of Web 2.0., many organizations begin to use collaborative thinking to present the practical solution called group knowledge creation. Group knowledge creation is an interactive process of brainstorming and sharing knowledge with people to complete a common goal collaboratively. In the process, organization will embody knowledge externalization, knowledge combination and knowledge internalization three processes of knowledge conversion. Some studies show that 90% CEOs’ reports are completed by teamwork. Within the popularity of group knowledge creation, we developed the group decisional supporting system called TeamSpirits. TeamSpirits is a collaborative platform which is suitable for embodying knowledge externalization, knowledge combination and knowledge internalization to help teams create knowledge. In order to understand teams use TeamSpirits for creating process of group knowledge, this study uses the laboratory experimental method of the pretest-posttest to research group knowledge creation. The purpose of discussing three different modes of TeamSpirits, Face-to-face and E-mail (the traditional way) is to find out the best way for team to embody the knowledge conversion process of knowledge externalization, knowledge combination and knowledge internalization, let team member be willing to share their knowledge with others and adopt it. The study shows that teams use TeamSpirits its knowledge externalization, knowledge combination and knowledge internalization are significantly higher than use Face-to-face and E-mail and team members' knowledge-shared intention and knowledge adoption are higher, too. This study can be an index of TeamSpirits to apply in the organization of group knowledge creation and to create better knowledge.
