Expecting substantial savings and improved public services - a trend further accentuated by the financial and economic crisis beginning in 2008 - OECD countries have invested in the development of e-government services over the past 10-15 years. They have used information and communication technology (ICT) to automate a broad range of internal functions, improve business processes within public organisations and across organisational boundaries, and deliver high-quality services to users - whether citizens, businesses or government employees. E-Government was seen as the ideal solution to the lack of coherency in public service delivery, as well as a way to free up resources through efficiency and effectiveness gains. However, despite the initial exceptional take-up, governments later saw low adoption and low use of e-government services which are still far from satisfactory today. The report gives a broad description of the shift in governments' focus on e-government development - from a government-centric to a user-centric approach. It gives a comprehensive overview of challenges to user take-up of e-government services in OECD countries and of the different types of approaches to improving it. The monitoring and evaluation of user take-up are also discussed, including the existence of formal measurement frameworks. Good practices are presented to illustrate the different concrete approaches used by OECD countries.
