In this article we describe and discuss means that foster the emergence of innovation through representational methods which interrelate manual modeling with playfulness. Based on the observation that demands to innovation processes have changed significantly in recent years due to changed collaboration forms, like co-configuration or open innovation, we look for a methodological approach able to deal with such collaboration forms. We describe and discuss a methodological approach on how innovation processes in heterogeneous – interdisciplinary, cross-functional and interorganizational – groups can be kicked off to bring about collectively shared understanding, as well as the ability to develop creative ideas. The approach relies on a playful modeling methodology, which is based on the hands-on creation of visualizations and physical models in connection with their verbal explanation and narration. With reference to two case studies we report and discuss experiences of applying the methodology.
