“…It empowers organisations to add value and construct practical and economic solutions in alignment with current and future business needs based on an iterative process model and bestpractice framework. The TOGAF also relates to the government context, where it has been widely implemented and has exhibited several strengths, such as a developed process, strong documentation, and a robust modelling language (ArchiMate) [35]. Within the TOGAF, the Architecture Development Method (ADM) is a core method that comprises several steps involving establishing and developing architecture solutions content and then transforming and governing the recognition architectures [11,36,37].Thus, this study adopted TOGAF to address the requirements for g-cloud implementation within the context of Saudi Arabia.…”

Digital technologies, such as cloud computing, have transformed business activities, particularly in the public domain. In the corporate sector, where cloud computing technology has long been implemented, some organisations have succeeded, while others have been less successful. Saudi Arabia has enthusiastically supported the move to cloud computing technology; however, from a business perspective, its implementation of government cloud technology is still relatively nascent and has faced numerous challenges. The existing literature suggests that the government cloud migration depends not only on project drivers, but also on considerable barriers, which often delay successful implementation. Furthermore, many current barriers and drivers clearly involve the roles of cloud vendors, meaning that cloud vendors must be fully engaged in order to develop comprehensive solutions. Addressing this phenomenon from the lens of enterprise architecture (EA) may support the development of appropriate deployment requirements for optimal government cloud implementation. Thus, this paper is a research in progress that analyses the major barriers and drivers affecting cloud implementation in public organisations, taking into consideration the perspectives of cloud consumers and vendors. This paper also introduces a mapping conceptual model throughout The Open Group Architecture Framework (TOGAF) that supports a novel framework for tackling these barriers and their influences and enhancing drivers via a set of requirements.

“…Enterprise Architecture practice facilitates enterprise analysis and holistic design of information systems. Enterprise Architecture comprises of frameworks and methodologies that guide the transformation from the as-is situation of the enterprise to the desired future state (Mohamed, Galal-Edeen, Hassan, & Hasanien, 2012).…”

“…From the literature reviewed, there appears not a single process that is readily available that could be applied by developing countries to help them select an appropriate EAF (Bhupesh, 2015). The existing research shows that ranking and comparing enterprise architecture frameworks has been done for many purposes other than for e-Government solutions in developing countries (Bonnet, 2009;Cameron & McMillan, 2013;Mohamed et al, 2012;Session, 2007).…”

The paper discusses the findings of the case study of applying multiple-criteria decision-making (MCDM) method to select attributes of the Enterprise Architecture (EA) frameworks for an e-Government implementation in a developing country. The paper follows on earlier work by the same authors, which focussed on identifying critical success factors to deploy a good enterprise architecture proposed for e-Government projects in Botswana. The research continues to contribute to an e-Government service architecture, and here to explore the processes of selecting an appropriate enterprise architecture framework in the context of a developing country such as Botswana. This selection process aligns the organisational goals with the known attributes of EA Frameworks. The authors apply an MCDM tool, the Analytical Hierarchy Process (AHP) to select EA frameworks attributes from four alternatives which are; the Zachman Enterprise Architecture Framework (ZEAF), Federal Enterprise Architecture Framework (FEAF), The Open Group Architecture Framework (TOGAF) and Treasury Enterprise Architecture Framework (TEAF). These frameworks constitute the four common EA frameworks for e-Government projects. The research concludes that adopting enterprise architecture when developing e-Government helps to visualise business functions and to support ICT comprehensively. The government must select a suitable EA framework before they implement Enterprise Architecture. Also, the findings demonstrate that ZEAF attributes are the most preferred attributes. The results are also consistent with the literature review, and they establish the viability of utilising MCDM methods in EA projects to improve decision making.

“…Multi-tier and service-oriented architectures combining reusable service modules or component-based approach, which are considered to tackle flexibility and compatibility issues, reduce the complexity, implementation time, and the development and communication cost (Zhang et al 2008;Mohamed et al 2012;Paul and Paul 2012;Janssen et al 2003;Brustel et al 2012; Machado and Parente de Oliveira 2011).…”

System architecture plays a crucial role in the establishment of Digital Government infrastructure. Over recent decades, various architectures have been introduced by scholars for the establishment of Digital Government infrastructure. However, there is no uniform agreement on Digital Government architecture concepts required for Digital Government infrastructure. To more thoroughly examine the Digital Government architecture introduced in this article, we collected 103 papers published between 2003 and 2020 retrieved from five leading literature databases. To conduct our research, we followed best practice scholarly accepted guidelines for researchers. Per the guidelines, we formulated research questions and employed an approach based on specific inclusion and exclusion criteria to meet our research goals. Our study found evidence that there is a lack of knowledge in terms of the state-of-the-art in Digital Government infrastructure and its challenges concerning existing Digital Government architectures. We identified a set of primary Digital Government architecture characteristics and building blocks on which the Digital Government infrastructures are built. These components are meant to improve the design of future Digital Government systems and applications. Furthermore, our research revealed a need for designing a reference architecture to provide government organizations with the best practice knowledge of already existing Digital Government architectures.
