Planning support for enterprise changes

Part 3: Change Management and TransformationInternational audienceEnterprises have to react to changes with an increasing speed in order to stay competitive. Many approaches support the modeling of enterprise architectures but lack an evolution of enterprise architectures through demonstrating a transformation path from one architecture state to another. Enterprises know their strategic goals and are able to model them, but are not supported towards achieving these goals in terms of developing their architecture. We want to improve the current manual creation of the transformation paths in enterprise architecture planning by providing possible and sound sequences of actions as part of a roadmap from the current to a desired target architecture.Therefore, we present a solution that supports the enterprise architect with proposals for a transformation path from the current to the target state considering dependencies to be taken into account during the enterprise transformation

A Technique for Annotating EA Information Models with Goals

Abstract. Many of today’s enterprises experience the need to establish and conduct management processes to ensure closely alignment between business and IT. Enterprise architecture (EA) management provides a model-based approach to understand and evolve the complex dependencies between the enterprise constituents, as e.g. business processes and business applications. In recent years the understanding of EA management in literature and in practice has converged, but up to this point no commonly accepted standard information model for EA management nor a standard set of goals verifying the overall objective of business/ITalignment have been devised. Grounded in indications that such models and goals are highly enterprise-specific, this paper presents a method for flexible combining EA-relevant goals and EA information models to optimally support EA management in a using company

Exemplifying a Framework for Interrelating Enterprise Architecture Concerns

Abstract. In recent years, enterprise architecture (EA) management has gained increasing attention as means to support enterprises in adapting to changing markets and in seizing new business opportunities. A multitude of approaches and frameworks making prescriptions on how to document the different states of the EA have been developed. These approaches target different purposes and correspondingly different concerns (areas of interest) in the architecture. Hence, an enterprise seeking to develop or evolve an organization-specific EA documentation technique most likely runs into difficulties to understand the interdependencies between different frameworks and approaches. The paper addresses the aforementioned challenge by presenting a framework for EA concern interrelations, which can be used to systematically analyze the concern relationships of different approaches. The applicability of the framework is demonstrated by means of a case study from the automotive industry, in which the framework is used for the development and enhancement of an EA description for risk management. 1 Introduction an

IT Landscape Management Using Network Analysis

Part 1: Full PapersInternational audienceDependency analyses have become crucial in today’s enterprise architecture practices, which usually face complex IT landscapes with highly interdependent applications. In such environments, a deep understanding of the application’s context is essential to determine its qualities and project its further evolution. However, method support for making this context a tangible IT landscape management part and thus facilitating quantitative decision making still seems expandable. Based on the representation as a network of applications and their relations of data exchange, this paper therefore suggests ways to support the IT landscape’s examination through network analysis. We develop this approach based on a combination of theoretical explanations, past empirical findings, and experiences taken from the architecture practices of four sample organizations. We illustrate and evaluate our approach with a short case study. Our approach, developed and illustrated in close alignment with insights from actual practice, thus offers ideas and advice for researchers and practitioners alike

How Enterprise Architecture Formative Critical Success Facets Might Affect Enterprise Architecture Success: A Literature Analysis

Part 4: Enterprise ArchitectureInternational audienceThough Enterprise Architecture (EA) is getting increasing attentions from both academics and practitioners, EA research around EA success factors remains modest and immature. This study explores how EA formative critical success facets/factors would affect the achievement of EA success. This research highlights the importance of four mediators, i.e., (I) Real and mature business needs; (II) Real and continuous commitment; (III) Actionable EA programs; and (IV) Well-controlled execution of EA programs. This study deepens our understanding of EA success and would be of explanatory contribution to EA value development and action-guiding contribution to EA adoption and implementation
