Enterprise architecture (EA) is the definition and representation of a high-level view of an enterprise‘s business processes and IT systems, their interrelationships, and the extent to which these processes and systems are shared by different parts of the enterprise. EA aims to define a suitable operating platform to support an organisation‘s future goals and the roadmap for moving towards this vision. Despite significant practitioner interest in the domain, understanding the value of EA remains a challenge. Although many studies make EA benefit claims, the explanations of why and how EA leads to these benefits are fragmented, incomplete, and not grounded in theory. This article aims to address this knowledge gap by focusing on the question: How does EA lead to organisational

Abstract. Enterprise Architecture (EA) is becoming an increasingly mature field of work, but many large organizations still struggle with implementing an integral and truly effective EA function. The literature provides a fragmented picture of the EA function, describing the various separate elements that make up the total package of activities, resources, skills, and competences of the EA delivery function. In our view, the EA function reaches beyond EA delivery and also includes the stakeholders, structures and processes involved with EA decision making and EA conformance. A holistic and integral view on the EA function is essential in order to properly assess an EA function on its performance, and to allow identifying the key points of improvement. In this article, we give such a description of the EA function, which provides the reference model in EA function performance assessments as part of our

Abstract — In recent years, enterprise architecture (EA) management has become an intensively discussed approach in both industry and academia for managing the complexity of an enterprise from a holistic perspective. While there is a strong academic and practical interest in EA frameworks and EA modeling, there is a notable insecurity about the cost benefit ratio of EA. In this paper, we address this research problem with a qualitative research design. We conduct a series of semistructured interviews with industry experts on enterprise architecture in order to identify classes of EA goals, corresponding EA frameworks adoption to achieve these goals and employed EA benefit assessment approaches. The findings point to, among others, a fairly stable set of EA goals that shift over time and EA frameworks that lack modularity and adjustment capabilities to easily customize towards these goals. This paper is part of an ongoing exploratory research that aims at researching which benefits emanate from EA.

The term "heterogeneity " is widely used to describe complex IT systems and can refer to various characteristics, such as vendor, technology, or semantic diversity of the systems components. However, no commonly accepted definition or quantification of this “diversity ” can be found in IS literature. In this article we transfer well-studied measures from other disciplines (especially economics and the anti-monopoly legislation) to heterogeneity in IT landscapes. The two main contributions of this article are A) the definition of heterogeneity in an IT landscape as a statistical property – which therefore can be measured by statistical indexes and B) a generic approach to quantify heterogeneity in IT landscapes. The applicability of the conceptualization and the approach to quantify heterogeneity is demonstrated in two real IT organizations.

Various claims have been made regarding the benefits that Enterprise Architecture (EA) delivers for both individual systems development projects and the organization as a whole. This paper presents the statistical findings of a survey study (n=293) carried out to empirically test these claims. First, we investigated which techniques are used in practice to stimulate conformance to EA. Secondly, we studied which benefits are actually gained. Thirdly, we verified whether EA creators (e.g. enterprise architects) and EA users (e.g. project members) differ in their perceptions regarding EA. Finally, we investigated which of the applied techniques most effectively increase project conformance to and effectiveness of EA. A multivariate regression analysis demonstrates that three techniques have a major impact on conformance: carrying out compliance assessments, management propagation of EA and providing assistance to projects. Although project conformance plays a central role in reaping various benefits at both the organizational and the project level, it is shown that a number of important benefits have not yet been fully achieved.

Abstract. Enterprise Architecture (EA) is increasingly being used by large organizations to get a grip on the complexity and inflexibility of their business processes, information systems and technical infrastructure. Although seen as an important instrument to help solve major organizational problems, effectively applying EA seems no easy task. Efficient collaboration between architects and EA stakeholders is one of the main critical success factors for EA. The basis for efficient collaboration between architects and EA stakeholders is mutual understanding. In EA research, there has been much focus on the role of the architect; there is little research on the EA stakeholder. In this article we present the cognitive structure of four EA stakeholder groups, revealing how they expect the EA function to help them achieve their goals. With this we gain understanding of the EA stakeholder and provide the basis for better collaboration between architects and EA stakeholders.

Abstract In this study we analyze co-adoption of several modern concepts of enterprise architecture creation and describe real-time business processes generation on global cloud-based self-generated business service basis to increase the agility of enterprise. We simulated the process of generating the business model started by particular business request with the support of subject-oriented business process management approach that results in particular business process architecture, which is approved or rejected/corrected by board of directors and architectural committee of the enterprise. During that generation all necessary requirements for supporting resources, such as information, know-how, intellectual and professional skills, inputs and outputs, quality and operational risk limitations, moderation, control and monitoring, are formed. On a next twist of the development all formed requirements are to be satisfied by appropriate selections from the cloud facilities and again approved. Finally after several iterations business model will be created in reality and could be executed with predicted results. Briefly that means that certain sets of valued and weighted business process replicas are located in Clouds. In addition to that, in this article we have provided the advanced view on the topic with attempt to install a virtual SOA torrent that catches services from the Internet and makes them available to customers and represents a business service basis for real-time business processes.

Enterprise architecture (EA) management has become an intensively discussed approach to manage enterprise transformations. Despite the popularity and potential of EA, both researchers and practitioners lament a lack of knowledge about the realization of benefits from EA. To determine the benefits from EA, we explore the various dimensions of EA benefit realization and report on the development of a validated and robust measurement instrument. In this paper, we test the reliability and construct validity of the EA benefit realization model (EABRM), which we developed based on the DeLone & McLean IS success model and findings from exploratory interviews. A confirmatory factor analysis confirms the existence of an impact of five distinct and individually important dimensions on the benefits derived from EA: EA artifact quality, EA infrastructure quality, EA service quality, EA culture, and EA use. The analysis presented in this paper shows that the EA benefit realization model is an instrument that demonstrates strong reliability and validity.

Adopting an engaged scholarship, particularly design science research approach, we explore design principles for heterogeneity decisions in enterprise architecture management (EAM). The holistic design of an enterprise’s business processes and the architecture of IT systems has been an important IS research topic for many years, but the majority of past studies in our discipline took predominantly a decision-making perspective. There is a significant gap in our current understanding on how to design and plan an EA in order to serve strategic enterprise requirements. Thus, with this research-in-progress we address this gap in the literature and leverage the complementarities between EAM problem domain and design science research knowledge. In particular, we draw upon the latter as a methodological guideline for developing design principles and on the former as a conceptual guideline to develop design principles that address the particular class of heterogeneity problems in EAM.
