Enterprise architecture management provides the mechanism for governing enterprise transformations required by changes in the environment. In this article, the authors focus on changes that result from the analysis of information system risks and of their impacts on the services delivered by the enterprise. The authors present how the concepts of an information system risks management domain can be integrated into the ArchiMate enterprise architecture modelling language. This article approaches the conceptual integration in two design cycles: first, this article will consider information security risks, and then the authors generalize to information system risks. Additionally, the authors illustrate the application of the proposed approach and demonstrate the benefits of the integrated model through the handling of a case study, first in the domain of information security, and then in the domain of information privacy. The generalized risk-oriented EA model leads to a risk integration framework for the service-oriented enterprise.

Strategic sourcing, as a critical area of strategic management, is centered on decision-making towards achieving value-driven targets. Many companies face challenges in obtaining the benefits associated with effective strategic sourcing decision-making. Enterprise modeling can contribute to strategic sourcing decision-making by helping in the conceptualization, design and exploration of multiple strategic options for better decision-making. In this article, the authors explore a solution approach that refines the existing Enterprise Engineering (EE) modeling discipline into a Service-oriented Enterprise Engineering (SoEE) modeling discipline, by founding it on the novel application of the Viable Systems Approach (vSa) towards strategic (sourcing) decision-making. The proposed modeling discipline provides (1) the systemic viewpoints to interpret complex sourcing phenomena; and (2) the outside-box models to specify the value-driven interactions of an enterprise (as a system) with other actors. Finally, to operationalize the modeling discipline the authors introduce the conceptual basis (C.A.R.S) of a modeling language to apply the SoEE viewpoints and develop the related models for supporting strategic sourcing decision-making. The paper elaborates on preliminary ideas presented at the SoEA4EE 2013 workshop.

A new class of information system architecture, decision-oriented service systems, is spreading more and more. Decision-oriented service systems provide services that support decisions in business processes and products based on the capabilities of cloud-computing environments. To pave the way for the creation of design methods of business processes and products based on decision-oriented service systems, this article introduces a capability-oriented approach. Starting from technological capabilities, more abstract operational and dynamic capabilities are created. The framework created is based on an integrated conceptualization of decision-oriented service systems that allows capturing synergetic effects. By creating the framework, the gap between the technological capabilities of technologies and the strategic goals of enterprises shall be narrowed.

Modern enterprises have to respond to the challenge of changing competitive situations by being able to adapt their business models and the supporting IT systems. Service-orientation and cloud computing offer established approaches for achieving flexibility in the use of computing resources and sourcing strategies. This requires promoting systematic development and management of capabilities to key activities. To ease the adaptation of business services to changed business needs a complementary abstraction layer, namely, “Capability as a Service” (CaaS) should be considered. The primary purpose of this layer is to support the capture and representation of the factors that are decisive for flexibility in business services. The main contributions of this paper are (1) motivating the additional capability-focused abstraction layer by an industrial application case, (2) the concept of CaaS including methodical aspects and technology for delivery, and (3) an initial model of capabilities for the industrial application case from utilities sector.
