Christoph Riedl elaborates conceptual solutions and tool support for networked environments. The author draws on the fields of new service development and open innovation, in particular building on online communities. Based on the design science paradigm, the author offers guidelines how tool support for online innovation communities can be developed.What Makes E-Services Different?; Open Innovation in Service Ecosystems; Idea Ontology; Prototype Development; Idea Rating Mechanisms Dr. Christoph Riedl completed his doctoral thesis under the supervision of Prof. Dr. Helmut Krcmar at the Chair of Information Systems at Technische Universit?t M?nchen (TUM). He is currently a Post-Doctoral Fellow at Harvard University.Electronic services delivered over the Internet are gaining importance in the business world and give rise to the Internet of services and service ecosystems. Now, a challenging question emerges: How can we develop new and innovative services in these networked environments?
