“…Guijarro [17] had examined policy and practice in selecting standards for e-government interoperability frameworks and found that, while open standards are being enforced throughout all frameworks, de facto implementations reveal that more often than not proprietary technologies and specifications are used. There is evidence that developing and implementing enterprise architectures in e-government comes along with significant challenges such as handling the complexity and the ability for implementation and governance ( [21], [25], [27]). …”

Research has revealed the entanglement of e-government strategy and information infrastructure and that the control of infrastructures often remains an illusion as actual development and implementation is challenged by a constant drift. However, guidelines for public sector CIOs how to deal with these challenges remain scarce: Are governments well advised using architectures and other conceptualizations as tools in a top-down implementation of an infrastructure based on a preset interoperability strategy? Or should governments rather develop contextual strategies that build on the understanding of the actual drift of infrastructures and employ selected architectures only as facilitators for stakeholder communication during the next phase of interoperability achievement? In view of nowadays available theoretical reflections, the case of Egypt is analyzed to examine the role of service-oriented architecture in the control and drift of the G2G infrastructure.Findings reveal that what at first seemed to be an immature vendor-driven "technology-first" approach with a clear absence of IT governance strategy, in retrospect can be considered as the appropriate choice of architecture because it has successfully impacted agendas of most local stakeholder to move into the direction of e-government interoperability. Attempting to generalize, it is suggested that strategies towards e-government interoperability should select architectures based on reflection of the specific implementation context: to embrace existing infrastructure components, to be comprehensible and acceptable by the stakeholders involved, to be suitable for designing and standardizing the next generation of component interfaces, and to provide a timelimited frame for "tinkering," i.e. allowing stakeholders to find their own way of embracing and implementing the concepts in focus.

“…It also focuses, to a large extent, on the definition aspect of EA, such as frameworks and modelling (Tamm et al 2011;Ylimäki 2006;Schӧnherr 2009;Nogueira et al 2013). Only recently have more fundamental issues such as the value of EA (Tamm et al 2011), realised benefits (Van Der Raadt 2011Lange, Mendling, and Recker 2012) and organisational implementation of the EA function (Aier and Schelp 2010;Hjort-Madsen 2006) gained attention in empirical inquiry.…”

As a tool for management and planning, Enterprise Architecture (EA) can potentially align organisations' business processes, information, information systems and technology towards a common goal, and supply the information required within this journey. However, an explicit view on why, how, when and by whom EA artefacts are used in order to realise its full potential is not defined. Utilising the features of information systems use studies and data from a case study with 14 EA stakeholder interviews, we identify and describe 15 EA artefact use situations that are then reflected in the related literature. Their analysis enriches understanding of what are EA artefacts, how and why they are used and when are they used, and results in a theoretical framework for understanding their use in general.

“…Nevertheless, EA captures and represents knowledge about the organization decision-making dynamics. Accordingly, this approach has been applied to support Information Systems design in several organizations worldwide, e.g., governmental organizations (e.g., Martin et al 2004;Hjort-Madsen 2006), retail industry (Stecher 1993;Vasconcelos et al 2003) and furniture manufacturing (Xu et al 2007). (Shunk et al 2003) further uses an EA approach to analyze the process interactions and to establish the supply chain process integration in the defense electronics industry.…”

An enterprise architecture approach to forest management support systems design: an application to pulpwood supply management in Portugal

et al. 2011

A key requirement for the success of a forest management information system is that it may effectively address its users' needs. Yet, the development of models and methods to address-specific forest ecosystem management processes has not been matched by architectures that may take into account the human dimension of information systems. This paper presents an approach to pulpwood supply system architecture. Emphasis is on participatory business modeling that may effectively address users' needs and enhance system resilience. An Enterprise Architecture methodology is proposed so that the information systems' functional requirements for pulpwood supply may emerge from business and information architectures in workshops with the stakeholders. Results of its application to a vertically integrated Portuguese pulp and paper company are presented. The case study focuses on processes and business information required to support the pulp mills entire pulpwood supply management. Results show that the proposed approach addressed effectively end-users' involvement in pulpwood supply system design. It provided an architecture that addresses all stakeholders' perspectives and concerns and it was thus instrumental to develop a Pulp and Paper Supply Chain Process Framework. Results further show that it may effectively identify and integrate information systems' components, ensuring business information integrity.
