Enterprise Architecture in public sector
Information systems in public administration are complex and often difficult to develop. Enterprise Architecture provides the proven set of tools and methods to deal with this complexity; it provides different but interlinked views while keeping the focus on the whole life-cycle of processes, information and systems. Therefore, the Ministry of Finance has selected and put emphasis on expanding Enterprise Architecture in the public sector in Finland.
Enterprise Architecture (EA) has a few basic features; first, the environment is modeled on process, information, application and technology levels. Second, there are different levels of abstraction starting from abstract and logical down to technical and physical. Third, architectures are dynamic and developing from the target and reference definitions to the as-is descriptions. Our EA framework includes all these aspects.
The purpose of using Enterprise Architecture in the public sector is to improve performance and efficiency of ICT. Especially EA is aiming to increase the interoperability and information sharing between organizations and solutions. Interoperability will lead to positive consequences like cost-efficient system development, fast and lean administrative processes and usable information contents.
The interoperability objective has been defined in the Act on Information Management Governance in the Public Administration (634/2011). This legislation obliges all public administration organizations to define the as-is and target architecture in their own area. The Public Administration’s common Architecture guides and aligns the architecture work in the sectors and Ministry of Finance is responsible for developing and maintaining this top-level view. Ministry of Finance is authorized to lay down decrees concerning information architecture, information systems architecture and technical architecture.
