The main driver for ICT use in Norway was and remains internal efficiency through automation of administrative processes. Nonetheless, public sector reform has been a main driver of the development of e-government which is seen as an instrument for providing better quality services, reducing complexity and user orientation of the public sector. Decentralisation of public management has had an impact on e-government implementation, however, within this general approach, there have been swings towards and away from centralising certain elements of ICT use in government. The advancement of the information society and e-government developments at EU level have also provided important cases for e-government development in Norway.
