The chapter presents an overview of the evolution of e-Governance with an emphasis on the multidimensional role played by Information and Communication Technologies (ICTs) for governance. The aim is to learn from the past and put current policy developments in future perspective. The chapter builds on an analysis of the policy landscape and academic debate on e-Government and e-Governance and, in this connection it proposes to re-define the theory and practice of e-Governance. In order to do so, an original theoretical and interpretative framework to assess the public values underpinning the abstract construct of ICT-enabled governance is presented. Going further, the chapter set the basis for the future of e-Governance discussing the debate generated around the emerging field of ICT for governance and policy modelling, which can be considered as an umbrella term indicating the interplay between collaborative ICTs that are applied in order to achieve the target of participative, evidence-based governance and the related organisational and social processes associated with them. In this respect, the theoretical framework proposed is set out to help interpreting changes and developments towards the open model of governance enabled by ICTs. The chapter concludes outlining policy and research challenges for the future of e-Governance.
