Comparing Enterprise Architecture Frameworks – A Case Study at the Estonian Rescue Board

Anastasiia Okhrimenko
Every organisation has strategic goals it wants to achieve, and if it does not have an architecture combining all different elements such as business processes, enabling information systems, data flows and platforms, it will not be sure which investments will lead to achieving which objectives. Since there has not been any research like this performed for Estonian Government Organisations, the Estonian Rescue Board is taken as an example for conducting a case study. A systematic literature review is performed, for identifying Enterprise Architecture Frameworks, criteria for performing a comparative analysis of the framework as well as for the further evaluation at the Estonian Rescue Board. The identified final papers are analysed in order to answer the Research Questions (RQ). This helped to identify seven Enterprise Architecture Frameworks, which were evaluated and left only three frameworks for further implementation: The Open Group Architecture Framework (TOGAF), The Federal Enterprise Architecture Framework (FEAF), Service-Oriented Architecture (SOA). In the case study, the selected frameworks are modelled, showing 2 or 3 services in details, with further evaluation and discussion of them during the meeting at the Rescue Board, following the criteria, which are described in the literature review. Case study and on-site meeting at the Rescue Board set two main things to be the most vital while developing Enterprise Architecture Framework in the organisation: organising architecture into views that are subsets of the organisation information architecture and understanding how the goals in the organisation are supported. This can be a good backbone for further developing Enterprise Architecture in the Rescue Board, and other Estonian Government Organisations in general.
