This document outlines a roadmap for research in electronic governance over the next decade. It identifies four grand challenges: 1) Model-based collaborative governance to improve policy modeling and simulation; 2) Data-powered collective intelligence and action to leverage real-time open data; 3) Establishing a government service utility to provide ubiquitous, standardized public services; and 4) Developing a science base for ICT-enabled governance to systematize the field. For each challenge, it discusses short and long-term research directions to address gaps between current governance and a rapidly changing digital society. The overall goal is to transform policy-making using collaborative models, robust data analysis, and innovative digital service delivery.
