The aim of this chapter is to introduce an important area where ICT-Enabled Social Innovation has a particularly high impact, civic engagement, and building a typology of ICT-Enabled Civic Engagement innovation. The idea is that ICTs are becoming increasingly pervasive in the design, development and delivery of social innovation and of civic engagement initiatives and, as a consequence, the relationship between the state (intended as government as well as administration) and citizens is increasingly mediated by the technology in what is now widely known as Smart City/E-Government and relative applications. The provision of services by the state is not only set to become more efficient/effective because of the streamlining effects of the technologies, but also new services are emergent. The framework within which our typology is set out refers to the recent literature on social innovation and ICTs studying the types of relationships between government and citizens. The typology is developed upon empirical considerations based on 41 ICT-Enabled Social Innovation Initiatives selected during the 2014 – 2016 Mapping and Analysis carried out under the aegis of the JRC. The initiatives considered emerged from a research strategy based on systematic mapping of initiatives with policy relevance where ICTs played an important role either as enabler or driver of the innovation process. The initiatives selected had proven evidence of outcomes and/or long-term exceptional output. The sample includes a wide variety of cases from different sectors dealing with the different dimensions of civic engagement. There are grass-root movements and initiatives based on or oriented towards volunteerism; it includes also initiatives engendering citizen participation and those enhancing civic engagement through crowdsourcing/funding activities. The typology developed in this chapter highlights how ICTs underpin innovation in civic engagement initiatives in two main ways; first, it provides instruments and tools to deliver efficient and effective services through modernising existing processes and, second, it has become integrated part of the service design promoting the integration of existing services or the diffusion of new services. However, between the two modes there is not a clear-cut distinction between the roles and uses of ICTs.
