red except in articles offering basic definitions of e-services. A notable exception is the article by Menor et al. (2002) that also shows gaps that exist and points to research challenges. Service Delivery Platforms While several research results exist that can point in the direction of successful development of new e-services, there are certain gaps in NSD research with regard to key attributes of electronic services and their influence on NSD. In particular, current NSD methods are not well equipped to address the rapid nature and spe- cific cost structure found in electronic services. Moreover, current NSD methods are not well suited to fully exploit the various advantages offered by electronic ser- vices over non-electronic services. These are in particular the transparent feedback generated by service usage and potentials for continuous improvement and rapid deployment of service changes. This research only focuses on core NSD literature. However, there are other streams of research that might be suitable to target some of the key issues. We propose in particular that an open innovation process should be taken toward the development of new electronic services. Future research should address how the research gaps identified in this analysis of NSD literature can be addressed by other streams of research and how open innovation could be specifically used for the innovation of electronic services. To address the potentials of increased out- sourcing and also increase the speed of development NSD processes for electronic services could also be extended to include a specific step of searching for existing service components that can be reused. Literature on mash-ups could serve as initial guidance in this area. Furthermore, there are potentials of participatory development of new e-services and open innovation (e.g., Leimeister et al., 2009; Riedl et al., 2009a) that could provide useful for fast and successful development of new services. In summary, the research on electronic services in general and the develo
