We discuss how enterprise architecture management (EAM) supports different types of enterprise transformation (ET), namely planned, proactive transformation on the one hand and emergent, reactive transformation on the other hand. We first conceptualize EAM as a dynamic capability to access the rich literature of the dynamic capabilities framework. Based on these theoretical foundations and observations from two case studies, we find that EAM can be configured both as a planned, structured capability to support proactive ET, as well as an improvisational, simple capability to support reactive ET under time pressure. We argue that an enterprise can simultaneously deploy both sets of EAM capabilities by identifying the core elements of EAM that are required for both capabilities as well as certain capability-specific extensions. We finally discuss governance and feedback mechanisms that help to balance the goals of flexibility and agility associated with dynamic and improvisational capabilities, respectively.

New Avenues for Theoretical Contributions in Enterprise Architecture Principles- a Literature Review

Enterprise Architecture (EA), which has been approached by both academia and industry, is considered comprising not only architectural representations, but also principles guiding architecture’s design and evolution. Even though the concept of EA principles has been defined as the integral part of EA, the number of publications on this subject is very limited and only a few organizations use EA principles to manage their EA endeavors. In order to critically assess the current state of research and identify research gaps in EA principles, we focus on four general aspects of theoretical contributions in IS. By applying these aspects to EA principles, we outline future research directions in EA principles nature, adoption, practices, and impact.

Method Support of Large-Scale Transformation in the Insurance Sector: Exploring Foundations

Many enterprises need to handle programs that impose fundamental changes to the organization as well as the supporting IT systems. While general guidance for such transformations in form of methods, reference models, principles, etc. is available, the specific context of the insurance sector is often not considered. We conducted an interview series with informants from major European insurance companies to explore the specifics of enterprise transformation in the insurance sector. The results suggest amending existing transformation support methods by regarding transformation triggers, transformation program types and core techniques. E.g., transformations that deal with standardization, mergers and acquisitions and internal alignment are not sufficiently covered yet and techniques that deal with soft and social aspects of transformations are less visible in the insurance sector. Our findings create not only the basis for a wider survey to extend and validate initial findings, but also for comparing and discussing concrete enterprise transformation cases.

Management of Large-Scale Transformation Programs: State of the Practice and Future Potential

In addition to continuous, evolutionary optimizations, most enterprises also undergo revolutionary transformations from time to time. Knowledge about current corporate practice for coherent IT and business transformation is therefore very valuable. In this paper we present the results of an empirical study on the management of large-scale transformation programs that focuses on IT as much as business aspects. Companies that rate themselves as mature with regards to transformation management, assess certain transformation management components different than less mature companies. Cost reduction, revenue improvement, and agility improvement are the most relevant goals of transformation programs all these are business goals and not IT goals. Current state of the art transformation management can be classified into three approaches: Value-driven, ungoverned and change-driven. We found that no single management approach covers all these areas appropriately yet.

Development of Measurement Items for the Institutionalization of Enterprise Architecture Management in Organizations

While elaborate enterprise architecture management (EAM) methods and models are at architects' disposal, it remains an observable and critical challenge to actually anchor, i.e. institutionalize, EAM in the organization and among non-architects. Based on previous work outlining design factors for EAM in light of institutional theory, this work discusses the theoretical grounding of respective design factors and proposes measurement items for assessing the institutionalization of EAM in organizations. The work identifies measurement items for the factors legitimacy, efficiency, stakeholder multiplicity, organizational grounding, goal consistency, content creation, diffusion and trust, contributing to evaluate and inform EAM design from several, partially new perspectives.

Applying Design Research Artifacts for Building Design Research Artifacts: A Process Model for Enterprise Architecture Planning

(Springer, 2010-06-04)

Enterprise architecture (EA) describes the fundamental structure of an organization from business to IT. EA as a practice as well as a research topic has been around for several years. However, existing methods largely neglect the existence of time which is essential in order to systematically approach EA planning. The article at hand builds a process model for EA planning as a de-sign research artifact. We therefore use another more general design research artifact a method for process engineering in order to systematically build our proposed planning process. From a design science research (DSR) perspec-tive we demonstrate, how elements of the DSR knowledge base can be applied to create new DSR artifacts and how DSR might build a toolbox as it is availa-ble in other mature engineering disciplines.

Process Performance Management - Identifying Stereotype Problem Situations as a Basis for Effective and Efficient Design Research

Just recently many organisations get involved with process performance management (PPM). It appears, however, that PPM initiatives confront organisations with multi-faceted and complex challenges that call for a detailed problem analysis before any solution is eveloped. In this paper we introduce two patterns for identifying stereotype problem situations in design research (DR) and apply one to the field of PPM. The application gives detailed insights into typical PPM problem situations and illustrates the usefulness of our approach.

The design of ambient environments does not depend on technical issues exclusively but also on social aspects. There are several design specifications for ambient environments and corresponding development principles, a design method should address. In this paper, we review design methodologies concerning the coverage of existing design principles and their applicability for ambient environments. Because unprecedented, we introduce a methodology for Content-Centered Design of Ambient Environments (CoDesA) and apply this method in parts to an ambient bath environment

In order to identify and explore the strengths and weaknesses of particular initiatives, managers in charge need to assess the maturity of their efforts. For this, a wide range of maturity models has been developed, but there is no detailed methodical guidance how to extend these models. Therefore, we present a systematization of maturity model extensions.

Systematic development of business-driven requirements - using next-generation EIS design as an example

Despite many improvements to IT support for executives, they still complain that executive information systems (EIS) bear little relevance to their management task and fail even more to accommodate their working style. This indicates that business issues should more strongly drive requirements for next-generation EIS. The article contributes to such an EIS design by systematically developing requirements criteria that are more business driven than the state-of the-art. To do so, requirements lists of EIS, structural models of user satisfaction and technology acceptance are evaluated with criteria derived from the requirements engineering discipline. The findings show a dual gap: as the rigor of the models increases, they become less relevant for practice. In comparison, the requirements lists emonstrate relevance, but do not evidence strong rigor. To bridge this gap, this article applies the principle of economic efficiency to balance scientific rigor with relevance for practice. The findings should lead to better next-generation EIS design and should also be applicable to IS in general.Keywords: requirements engineering, next-generation executive informationsystems (EIS), principle of economic efficiency
