    Enterprise Architecture (EA) is currently accepted as one on the major instruments for enabling organisations in their transformation processes to achieve business-technology alignment. Despite that over the last years EA has been successfully adopted in many industries, Higher Education still represents one of the sectors with lower levels of adoption and maturity of EA practices. The present thesis puts the emphasis particularly on the study Enterprise Reference Architectures (ERAs), as a particular type of EA artefact, in Higher Education Institutions (HEIs). After formally clarifying the concept of ERAs and giving a panoramic view of the current state-of-the-art of existing HEI-oriented ERAs, the thesis proposes an artefact framework build through a Design Science Research (DSR) approach aimed to facilitate practitioners their (re-)use or application in their own real practical settings. The purpose of the constructed artefact is to support practitioners when conducting the necessary adjustments to exiting HEI-oriented ERAs in order to be successfully applied for their specific needs.La Arquitectura Empresarial (AE) es actualmente reconocida como una disciplina que permite configurar procesos de trasformación organizativa a objeto de alinear el negocio con la tecnología. A pesar de que en los últimos años la AE se ha ido adoptando progresivamente de forma exitosa en diversas industrias, la educación superior representa todavía hoy en día uno de los sectores con menores niveles de adopción y de madurez en lo que se refiere a las prácticas de AE. La presente tesis hace especial hincapié en el estudio de las Arquitecturas de Referencia Empresariales (AREs), entendidas como un artefacto específico de AE, en Instituciones de Educación Superior (IES). Así, después de clarificar formalmente el concepto de ARE y de ofrecer una visión panorámica del estado del arte relativo a las AREs para IES existentes, la tesis propone un framework de trabajo construido a través de un enfoque de investigación basado en la Ciencia del diseño destinado a facilitar su (re-)utilización o aplicación práctica en dominios de trabajo reales. El objetivo del artefacto es proporcionar soporte práctico a los profesionales para realizar los ajustes necesarios a las AREs para IES existentes para que puedan aplicarlas con éxito a sus necesidades específicas.L'Arquitectura Empresarial (AE) és actualment reconeguda com una disciplina que permet configurar processos de transformació organitzatius a fi d'alinear el negoci amb la tecnologia.

    Towards an understanding of business design within enterprise architecture management: a cautionary tale

    Includes bibliographical references.Business Design represents a set of concepts that are described in the literature as providing a sound foundation for sustainable competitive advantage into the future. The particular values underpinning Business design are based on the enablement of a design thinking approach to solving the imponderable problems that organisations regularly encounter. In particular, the application of a design thinking approach to Business Design requires that resultant system designs are economically viable and technologically feasible. Enterprise Architecture Management plays a vital role in supporting these latter two requirements. Yet the definition of Enterprise Architecture Management as the 'normative restriction of design freedom' (Deitz, 2011) implies constraints that could impose limits on such business design. Consequently, the qualitative inductive research described in this document was undertaken to explore the perceived paradoxical relationship between Business Design and Enterprise Architecture Management. This dissertation recounts the process and results of this research initiative based on data recorded during interviews with a number of management level staff at a leading South African Insurance organisation. The participants were intimately involved in a programme to, amongst other objectives, establish a platform to support enterprise-wide Business Design within Enterprise Architecture Management, a programme that was experiencing a number of challenges and that was still underway at the time of completion of this research. Findings arising from this research were that the varying perceptions and levels of commitment of business and IT stakeholders associated with the programme and its requirements, contributed significantly to these challenges. In addition to providing a rich description of the case organisation's journey towards the establishment of a Business Design platform, a sensitising framework – 'The 6 Cs Framework in Support of the Successful Enablement of Business Design within Enterprise Architecture Management' – is proposed as a useful tool to assist organisations that might be considering a similar programme in the future

    An investigation into the impact of enterprise architecture decisions on the responsibilities of software developers in companies that develop software

    Enterprise Architecture endeavours to resolve the complexity of increasingly distributed systems by aligning business vision with IT strategy, which in turn should reduce the overall costs of IT in the business and provide simpler, better and faster solutions to business problems. There are many Enterprise Architecture frameworks. The main purpose of most of these frameworks is to assist with the challenges of managing the increased complexity of distributed systems, aligning business vision with IT strategy and reducing IT costs. Many of the studies which produced the results stating Enterprise Architecture aligns business vision and reduces IT costs, were based on Zachman’s work, and most of the published Enterprise Architecture success stories focus on the benefits provided to the company with regards to IT. In contrast very little documentation could be found that addresses the impact of Enterprise Architecture implementations on the individuals and systems within a company. If the individuals as the main implementers of any strategy are impacted negatively by Enterprise Architecture management decisions, there would be a negative impact on the return on investment of the company. Enterprise Architecture allows the use of overlapping departments’ processes and data, which translates into less development time as system components would already exist. Changes that are made to the Enterprise Architecture result in several additional changes that had to be implemented by the software developers. These changes influenced the workload, roles and responsibilities of the developers in such a way that the development team became negative about the additional work. The purpose of this study was to investigate the impact of Enterprise Architecture management decisions on the responsibilities, work experience and attitude towards Enterprise Architecture of the software developers in a company that develops software by exploring and describing the nature of software development. Based on the findings of this study, a list of impact of Enterprise Architecture decisions on the responsibilities of software developers in companies that develop software were identified. In this respect, the study identified impacts of Enterprise Architecture management decisions as well as possible solutions to these impacts.ComputingM. Sc. (Information Systems
