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

Alignment and Maturity Are Siblings in Architecture Assessment

Abstract. Current architecture assessment models focus on either ar-chitecture maturity or architecture alignment, considering the other as an explaining sub-variable. Based on an exploratory study, we conjec-ture that both alignment and maturity are equally important variables in properly assessing architecture organizations. Our hypothesis is that these variables conceptually differ, correlate, but do not explain one an-other. In this paper we describe our Multi-dimensional Assessment model for architecture Alignment and architecture Maturity (MAAM), which contains six main interrelated sub-variables that explain both alignment and maturity. We used existing models, literature from business and IS domains, and knowledge gained from previous research to identify the explaining variables. We constructed MAAM using structured modeling techniques. We are currently using a structured questionnaire method to construct an Internet survey with which we gather data to empirically validate our model. Our goal is to develop an architecture assessment process and supporting tool based on MAAM.

A Meta-Language for EA Information Modeling -- State-of-the-art and Requirements Elicitation

Enterprise architecture (EA) management has not only recently gained importance as means to support enterprises in adapting to a changing market environment and in seizing new business opportunities. This twofold role of EA management in transforming enterprises is connected to describing the current state as well as future states of the EA. Although different information models for the description of these states have yet been proposed in literature, no ’standard ’ information model exists, and the plurality advocates for the idea that such models are enterprise-specific design artifacts. In this paper, we explore the fundamentals of EA information modeling, namely the meta-languages underlying today’s models, and analyze their diversity. Based on the analysis, we elicit requirements for a ”unifying” meta-language. By showing that multi-purpose modeling facilities, as the OMG’s UML, fail to fully satisfy these requirements, we establish a future field of research – a meta-language for EA information modeling
