While standardisation efforts in Norway have fluctuated in terms of focus and intensity, standardisation has now emerged as a key priority in the e-government agenda. Frameworks for standards for interoperability and management of some data exist and continue to be developed through inter-agency working groups. The government has also taken a pragmatic approach to PKI by establishing regulatory and policy frameworks as well as technical requirements for the introduction of a common PKI solution for the public sector. The national e-procurement system is solid but take up has been lower than expected, despite demonstrated return on investments. Inter-agency collaboration is not considered a major challenge for the implementation of e-government, however few agencies are collaborating beyond the level of information sharing towards establishing a common framework for the delivery of joint services. Much of the collaboration is based on the joint exchange of information contained on individual data registers. Further improvements can be obtained by making a better use of data and information contained in the well-established public registers.
