摘要：For the agile development methodology that repeats the frequent releases and the short development periods, there are some value practices that we have to keep. Among them, three typical practices were selected: use of Web 2.0 collaboration tool, adoption of the test driven development (TDD) and refactoring. The agile practice that forces the communication between team members was defined with the use of Web 2.0 collaboration tool. When this is applied to the development method of open-source projects which are dispersed geographically, temporally and culturally, it is expected to raise the satisfaction of OS project users and to contribute the maturity of community. It was applied to the study models that were drawn out from the precedent studies. Today, OS project users are adopting diverse tools for the online communication. But the degree of communication that is emphasized in the agile methodology can be satisfied only with the use of two-way, open and communicable tools reflecting the characteristics of Web 2.0 rather than with the conventional one-way information transmitting tool. In this situation, it was examined how the conventional and the improved tools have influence on the users' satisfaction. This paper is focusing on the communication factor among 3 factors.
