“…Anchoring the EA initiative is problematic in the cases. The three sectors' management and staff indicated awareness and acceptance of the concept, but we argue that the challenges in facilitating the necessary governance structures are evidence of poor understanding of EA among the top management, since this is an imperative task for them (Lee, Oh and Nam, 2016). This finding is consistent with that of a Finnish public agency: 'The executive group has understood that EA is an important concept.…”

Enterprise architecture (EA) is a widespread approach for the development of new digital solutions in a planned and controlled way for large and complex organisations. EA is also viewed as a prerequisite for the digitalisation of the public sector. However, public sector organisations struggle to implement EA programmes, and research has demonstrated that organisational and managerial issues are critical obstacles to EA implementation. This study aims to increase our understanding of EA implementation in the public sector by investigating the central challenges for EA initiatives and to trace the progress of current EA initiatives in the Norwegian public sector. An additional goal is to disclose some ways to improve the situation. We conducted three interpretive case studies in the hospital, higher education, and labour and welfare sectors. We have identified 28 challenges to the EA initiatives. We find that organisational and technical complexities, as well as a limited understanding of EA and lack of formal EA governance mechanisms, are significant obstacles. Among others, the lack of understanding of EA and its methodology will lead to problems with anchoring the EA approach in the organisation and facilitating the necessary EA arrangements to induce the promised benefits of EA, which are necessary requirements to establish the EA initiative’s legitimacy and foster the organisation’s willingness to implement change. Our study provides four lessons learned for planning and implementing EA initiatives, as follows: #1. It is advisable to take small steps. #2. The use of external consultants should be carefully considered. #3. Formal architectural governance mechanisms are important for legitimacy and enforced use. #4. Executive commitment and understanding of EA are crucial for achieving a sustainable EA initiative. Finally, we find a common evolution of the EA initiatives through the phases of optimism, resistance, decline and finally, reconsolidation of the most persistent ones.

Various understandings of enterprise architecture (EA) exist and there is no agreement on them. The various definitions of EA are not always complementary but sometimes in opposition. Within this study, we conduct a systematic literature review to analyze explicit definitions of EA. Based on concepts from the academic field of terminology, we have broken down these definitions into many parts in order to examine each part individually before making generalizations. The findings show how some of the EA definitions are implicit, incomplete, complex, and incoherent.

The functional priority of Health Information Exchanges (HIEs) is to ensure a timely transference of health data. Because of the frequency at which health records are transferred and the variety of health data HIEs receive, there are major challenges in efficiently accomplishing this. Cloud technology has become a generally accepted solution to remediate data transference issues but for HIEs, there are usually no clear paths to adoption. Enterprise Architecture (EA) is a tool that can ensure the smooth adoption and implementation of technologies. This paper is an extension of a proposal originally presented in the 14 th International Conference on Ubiquitous Information Management and Communication (IMCOM). In that article, an enterprise architecture that supports an HIE migration to a cloud architecture was proposed. This paper presents an EA migration plan and proposes an institutionalization framework, highlighting how the proposed EA can be applied to an HIE. A validation framework is provided as a means of testing the implementation of the HIE migration EA.
