Challenges in enterprise architecture management: Overview and future research

Due to the ongoing digitalization, today’s business world is changing rapidly. To stay competitive, companies need to adapt quickly to a fast changing-environment. This can be difficult, as organizations are complex systems consisting of many technical and infrastructural elements. Enterprise architecture management (EAM) is therefore increasingly important to companies when managing their infrastructure and adapting it to environmental changes. Despite its relevance, many companies struggle with challenges related to EAM tasks. Up to now, research lacks comprehensive reviews about the field of EAM and the related challenges. This article aims to close this research gap by conducting an iterative systematic literature review (SLR) to identify relevant EAM challenges in different EAM tasks. Hereto, based on Schmidt and Buxmann (2011), the tasks of EAM are divided into six dimensions — EA documentation, EA planning, EA communication and support, EA programming, EA implementation, and EA governance — which are investigated separately. This article’s result is a comprehensive overview of research in the field of EAM challenges. Additionally, interdependencies between the dimensions are assumed. Furthermore, an outlook on future research opportunities from an organizational, corporate governance, project, and technical perspective is provided.

A resource-based perspective of value generation through enterprise architecture management

Our study contributes to the nascent discourse on enterprise architecture management (EAM) benefits by proposing a theory-led, empirically validated model to explain how EAM benefits unfold. Drawing on the resource-based theory, and based on empirical insights from 8 case studies, we find that EAM does not create benefits per se, but only creates value if an organization develops four second-order EAM capabilities – EA modeling, EA planning, EA implementation, and EA governance. The discovery that EAM resources only unfold their potential when forming EAM capabilities casts doubt on the established practice of initiating EAM as a modeling and documentation endeavor.

Ea Governance towards Sustainability of Ea Practices in Digital Government: A Systematic Review

Enterprise Architecture (EA) has been identified as one of the prime initiative to drive the establishment of digital government towards world class public service delivery. However, building upon several public sector agencies that had implemented these initiatives, it was reported as unfavourable in sustaining EA practices. This study aims to i. review and identify related issues ii. identify factors that influence sustainability of EA practices also iii. identify elements of EA governance. Through the systematic literature review (SLR) five related issues were discerned, four key factors were established in sustaining EA practices while five elements of EA governance emerged in the construction of EA governance framework.

Study on Enterprise Architecture Framework Model

As Enterprise Architecture Framework, a frame work to express a company’s information system architecture, ZEAF (Zachman EA Framework) was the first one presented by Zachman, followed by FEAF(Federal Enterprise Architecture Framework), TEAF (Treasury Enterprise Architecture Framework), etc. The necessity of a framework intuitively understandable and easy to use has been raised. Accordingly, EAFM (Enterprise Architecture Framework Model) is presented based on the analysis on an existing framework and the requirements from interviews with architecture experts. EA requirements and principles, EAFM’s structure consisting of EA Matrix and EA Governance are presented by embodying requirements for structuralizing EAFM in terms of a framework structure, view, and perspective.

EA 거버넌스와 EA 역량에 관한 실증적 연구 : 공공기관을 중심으로

EA, efficient and hierarchical Information Resource Management(IRM) tool of Korean public agencie is one of the core of carrying forward the e-Government initiative. The objective of the paper is to study empirically whether using EA Governance for Controlling EA is related with their EA competency or not. the 190 person in charge of Information System service division are included for analysis. The various hypotheses established are validated by structural equation in SPSS and AMOS 18.0. The results shows that EA management and EA utilization of EA competency level was affected by EA Function, EA Organization and EA Human Resource of exogenous variable EA Governance but EA implementation level was not affected by EA Organization and EA Human Resource. also we investigated that the EA management level of endogenous variable EA competency was affected positively by EA implementation level and the EA utilization level of was affected positively by EA management level by stages.

An Enterprise Architecture Methodology for Business-IT Alignment: Adopter and Developer Perspectives

This paper proposes the use of an enterprise architecture methodology known as the Systemic Enterprise Architecture Methodology to determine the relevance of EA in addressing the business-IT alignment. A construct that characterized EA was developed based on review of the literature. A theoretical framework build upon the Systemic Enterprise Architecture Methodology (SEAM) was used based on a business-IT alignment market, in which supplier business systems compete to provide a value to an adopter business system. Data was empirically gathered based on survey respondents who are concerned with the adoption, planning and implementation of EA in their organizations. Respondents were managers and executives representing the IT and senior level management of public and private organizations in Malaysia. The data collected was then analyzed based on the following factors: (1) EA business issues; (2) EA environment; (3) EA governance; and (4) EA methods, tools and frameworks. Comparative analysis was carried out based on the four factors to examine the trend and status of EA adoption and implementation in Malaysia vis-a-vis the international scenario. Statistical analysis was used to validate the SEAM, which was found to be relevant in addressing the business-IT alignment.
