Enterprise Architecture in practice

The public sector’s architecture is hierarchically structured: the top level consists of the Public Administrations common architecture which defines general principles and common reference architectures. The next level is formed by 10 functionally grouped sectors like health, justice and defense. These sectors are again split into more detailed units.

The governance structure is similar. The overall Public administration’s common architecture is managed and maintained by one working group in the Permanent Advisory Committee on Information Management in Public Administration (JUHTA) which also acts as the steering group for the Enterprise Architecture work. Each sector works with similar governance model which includes a group of architects for defining and maintaining the content and a separate steering group for decision making.

There is also one sector dedicated for municipal organizations.

The method has been published in Public Administration’s Recommendations series (JHS) as “JHS 179 Developing the ICT services: The enterprise architecture development”. This recommendation defines a method for planning enterprise architecture to an organisation and describes the recommendations for creating the descriptions of the different areas of the architecture. The aim of this recommendation is to give a coherent planning method, context for the planning as well as unified description methods and models for developing the enterprise architecture for public administration organisations during the different stages of the developing process. The method is based on TOGAF.

Ministry of Finance has launched (Finnish for interoperability) – a portal for sharing interoperability assets among public administrations in Finland. enables the Finnish public administrations to share and reuse already existing semantic interoperability assets instead of re-inventing new ones.
