Abstract: Transport infrastructure systems are very complex and expensive. Projects to procure such systems are costly, long and complex to manage. The procurement context usually includes many collaborating organizations but often with different concerns and priorities, and many interactions to other parties. This makes the procurement very complex and entangled. DoDAF, MoDAF and TRAK are three architecture frameworks (AF) that model the whole enterprise/system life cycle that includes system procurement. They are expressed as metamodels. In this paper, we analyse various procurements strategies and identify the concerns that AFs should address. The TRAK AF is then applied to a Rail procurement case study in collaboration with Transport for New South Wales (NSW) in Australia to assess its effectiveness in meeting the procurement needs. In all stages of the study, TRAK is mapped and compared to DoDAF and MoDAF to examine whether DoDAF or MoDAF can cover the inadequacies of TRAK. This paper shows that there is a considerable number of procurement needs which are overlooked by these architecture frameworks. It proposes a metamodel driven expansion to these frameworks to improve their completeness and expressiveness. Collapse

Abstract: Enterprise architecture (EA) is a coherent whole of principles, methods, and models that are used in the design and realization of an enterprise’s organizational structure, business processes, information systems, and IT infrastructure. Recent research indicates the need for EA in small and medium-sized enterprises (SMEs), important drivers of the economy, as they struggle with problems related to a lack of structure and overview of their business. However, existing EA frameworks are perceived as too complex and, to date, none of the EA approaches are sufficiently adapted to the SME context. Therefore, this paper presents the CHOOSE metamodel for EA in SMEs that was developed and evaluated through action research in an SME and further refined and validated through case study research in five other SMEs. This metamodel is based on the essential dimensions of EA frameworks and is kept simple so that it may be applied in an SME context. The final CHOOSE metamodel includes only four essential concepts (i.e. goal, actor, operation, object), one for each most frequently used EA focus. As an example, an extract is included from the specific model that was created for the SME used in our action research. Finally, the CHOOSE metamodel is evaluated according to the dimensions essential in EA and the requirements for EA in an SME context. Collapse

Abstract: As a result of the rigor vs. relevance debate, researchers who focus on design research on organizational problems are beginning to focus on their research methodology's rigor. One of the means to lever the standards is the explicit establishment of defined language communities. This paper investigates to what extent current design research focusing on organizational problems is satisfying the requirements to establish such language communities. As research on organizational problems in IS research is still a very broad field, this paper focuses on research on enterprise architecture (EA). It contributes a state of the art overview on EA research regarding the research methodology employed and their language community state. Results show that local language communities in EA research do exist, but still have to lever their standards---both regarding the quality of the language communities and the quality of the design research.

Abstract: Market and environmental requirements call for constant changes in enterprises. To be able to record these changes in a structured way and to manage them it is helpful to use enterprise architectures as stable regulation frameworks. To support the development and the adaptation of the enterprise architectures there are numerous architecture methods (e.g. Zachman Framework, ARIS (Architecture of Integrated Information Systems), TOGAF (The Open Group Architecture Framework), DoDAF (Department of Defense Architecture Framework), BEN (Business Engineering Navigator), Semantic Object Model (SOM)), however, they often lack the necessary flexibility to enable a construction process adaptable to the given situation. This article presents a first approach towards making architecture methods flexible: meta models of the architecture frameworks of selected methods are generated and integrated into a joint meta model. The latter supports the situational adaptability of the enterprise architecture as the architecture method applied has been adapted. Collapse

Abstract: The challenge of IT management is today considerable. In industry, the organizational role of the Chief Information Officer (CIO) has been promoted as the owner of these challenges. In spite of a general acceptance of the problems associated with the responsibilities of the CIO, very little academic research has been conducted on the issues and constraints of this role. In order to address these shortcomings, this article presents the results of a survey in which Swedish CIOs have prioritized their most important concerns.In academia, a response to the IT system management challenges has presented itself in the discipline of Enterprise Architecture. The article argues that the CIO role is the primary stakeholder of Enterprise Architecture, so his/her need for decision support should guide Enterprise Architecture research and framework development. Therefore, the article presents a brief review over how well two existing Enterprise Architecture frameworks address the surveyed concerns of the CIO.Results from the survey indicate that the three highest prioritized concerns of CIOs are to decrease the cost related to the business organization, to improve the quality of the interplay between the IT organization and the business organization and to provide new computer-aided support to the business organization.The comparison between the CIOs' prioritization and the foci of the frameworks shows some discrepancies. The largest disharmony lies in the lack of decision support for issues related to the IT organization. Furthermore, support for explicitly estimating and managing costs is lacking within the frameworks. Collapse
