the design of an enterprise Architecture (EA) management function for an enterprise is no easy task. Various frameworks exist as well as EA management tools, which promise to deliver guidance for performing EA management. Nevertheless, the approaches presented by them stay either on a level too abstract to provide realization support or are far too generic, neglecting enterprise-specific EA related concerns. In this article, we discuss the architecture framework of the Open Group (TOGAF) and detail on its promising but nevertheless highly generic architecture development method (ADM). this article shows how the generic development steps can be complemented by a pattern based approach to EA management providing guidance for addressing specific EA related concerns with step-by-step methodologies as well as with corresponding viewpoints and information models.

the increasing level of collaboration among firms has necessitated the emergence of decision support tools that span firm boundaries. this essentially translates to decision support systems that seamlessly communicate and operate with disparate system characteristics. We propose and develop a multi-enterprise collaborative decision support system that aids in this process.

Methods for enterprise architecture, such as TOGAF acknowledge the importance of requirements engineering in the development of enterprise architectures. Modelling support is needed to specify, document, communicate and reason about goals and requirements. Current modelling techniques for enterprise architecture focus on the products, services, processes and applications of an enterprise. In addition, techniques may be provided to describe structured requirements, lists and use cases. Little support is available however for modelling the underlying motivation of enterprise architectures in terms of stakeholder concerns and the high-level goals that address these concerns. this paper describes a language that supports the modelling of this motivation. the definition of the language is based on existing work on high-level goal and requirements modelling and is aligned with an existing standard for enterprise modelling: the ArchiMate language. Furthermore, the paper illustrates how enterprise architecture can benefit from analysis techniques in the requirements domain.

the goal of the workshop is to clarify the relationship between business process management and service provisioning. this relatively recent area of interest requires the development of concepts and methods to assist the engineering and the management of Service-Oriented enterprise Architectures and their support systems. Five peer-reviewed papers have been presented during the workshop. they allowed to characterize the strong relationship existing between Business Process Management and Service oriented enterprise Architecture.

Modern enterprise application systems are parts of complex IT landscapes. the architecture of such a landscape may impose constraints upon the design of single applications, for example by the mandatory use of enterprise-wide reference architectures. It is of great importance for the sake of smooth operation and easy maintaining that single applications are com-pliant to the reference architectures. Checking this compliance is highly important for the architecture management to assure the quality of application systems. Unfortunately, current tool support is not flexible enough to easily check different aspects of architectural compliance. this paper proposes a rule-based approach based upon logic programming concepts towards a formalism for architectural compliance checking. In this approach, the architecture and design are represented as logical knowledge base that can be queried for architectural compliance. Furthermore, the paper presents a case study, in which the approach was prototypically implemented and applied in an industrial context.

enterprise Architecture is an important basis for aligning enterprise strategy with resources. Using a new perspective on economic exchange - the so-called Service Dominant logic - DYNSEA a dynamic enterprise architecture consisting of interacting service systems is developed. Central to DYNSEA is the co-creation of value with an actively involved customer, called prosumer. In DYNSEA service systems co-create services that are described by functional and non-functional properties and supplemented by meta services for managing the functional and non-functional properties of service.

enterprise Service Bus (ESB) plays an important role in enterprise SOA, and Java Business Integration (JBI) is the standard for Java based ESBs. As enterprises adopt ESB as the integration hub, how to preserve and leverage existing J2EE assets becomes an important question. While most ESBs allow J2EE applications to be deployed as-is, refactoring these applications allows them to take advantage of many service provided by the ESB platform and prompts service reuse. We will discuss our experience with a major US federal agency's SOA efforts where a legacy J2EE application was refactored to be integrated in a JBI environment. We will also show how infrastructure concerns such Quality of Services (QoS) were moved from the J2EE application to the JBI container.

enterprise Architecture deals withthe structure of an enterprise, relationships and interactions of its units. It provides a holistic approach to reconcile IT and Business concerns in an enterprise. Virtual enterprises are collaborative ad-hoc alliances of multiple enterprises for a specific business opportunity. this paper looks into boththe paradigms and enterprise Architecture viewpoint of Virtual enterprise. Service Oriented Architecture as a style of enterprise Architecture proves to be an enabler of Virtual enterprises at Business and Technology Levels. the three major challenges with Virtual enterprise are flexibility, adaptability, and agility. this paper discusses Virtual enterprise Architecture as a solution to these challenges, surveys research into formal models of Virtual enterprise Architecture and identifies current gaps in this research.

In this paper, application consolidation using enterprise Architecture methods is considered, with an ongoing project in the Swedish Armed Forces as the point of departure. the decision-making features of application consolidation are first analyzed and formalized from the perspective of decision theory. Applying these insights, a more practical framework is then proposed, based primarily on the ISO/IEC 9126 standard, the Ministry of Defence Architecture Framework (MODAF), and the formalism of Probabilistic Relational Models (PRM). this framework supports cost-benefit analysis of application consolidation decision-making, thus helping to make these decisions more structured and transparent.
