Community satisfaction has become a crucial aspect for success of emerging multimedia information systems. For measuring community satisfaction we propose a community success model (CSM) based on the seminal DeLone & McLean IS Success Model. CSM combines quantitative data collected through automatic monitoring of service usage with qualitative extracted from automatically generated questionnaires. As proof of concept we propose to apply our CSM to evaluate innovative community supporting services created within our regular lab course “Gaming Communities” at RWTH Aachen University. Video gaming is part of our new media culture, entertaining people of all ages. The satisfaction of gaming community members can influence the success of a game and therefore presents a relevant object of investigation for CSM.
