In increasingly complex and dynamic markets, small and medium sized enterprises (SME) face new challenges. Amongst others, these are innovativeness and technological expertise. In order to counteract the challenges, SMEs cooperate in corporate networks. Here, information and communication technologies are main drivers. At this point, Web 2.0 technologies are uttermost important. Until now, the development and implementation of Web 2.0 applications in SMEs was proceeded independently from the future users. We aim at bridging this gap by developing a participatory procedural model. The presented model includes the futures users from the beginning of the development process. The model respects SME specific characteristics.
