This research presents a co-developing service innovation imagery system that considers the service innovation imagery can be designed and created with their customers and appropriate collaborators in co-creation network. Default imagery reasoned by analyzing SMEs information, interaction pattern and cultural behavior so as to represent current status quo of the service to co-develop toward service innovation. In addition, we use metaphor statement as the representation of different kinds of user value (i.e., emotional, social-cultural environmental value) so as to build a knowledge based imagery bank for the co-developing process. The mechanism of the open group support system facilitates the interactions between different interpreters that derive and imply a set of value, such as emotional, social-cultural-environmental dimensional consumption values for the SME’s customers. In this research, our main goal is to propose an IT-based systematic approach for SMEs to co-developing their service innovation imagery with other actors and interpreters. The co-developing journey would facilitate SMEs to derive the service innovation imagery for service innovation.
