Quick Abstract

A key constraint for growing small and medium enterprises (SMEs) in South Africa is the business skills required to grow the enterprises through the stages of transformation. Business process management (BPM) is one of the skills that could add value during transformation. Understanding the stages of transformation during SME growth would assist to position BPM as an instrument of value for SMEs. These stages of SME growth are typically defined as part of the SME growth stage models. However, criticism against SME growth stage models is of concern. In this article, we propose the 5S SME Growth State Transition Model in order to counteract some of the criticisms. The value contribution of the Model lies in defining typical states associated with SME growth that can be used as input in research to position BPM as management approach during SME growth.

Towards a Conceptual Model for an e-Government Interoperability Framework for South Africa

Quick Abstract

In September 2016, the South African Government published a White Paper on the National Integrated ICT Policy highlighting some principles for e-Government and the development of a detailed integrated national e-Government strategy and roadmap. This paper focuses on one of the elements of such a strategy, namely the delivery infrastructure principles identified, and addresses the identified need for centralised coordination to ensure interoperability. The paper proposes a baseline conceptual model for an e-Government interoperability framework (e-GIF) for South Africa. The development of the model considered best practices and lessons learnt from previous national and international attempts to design and develop national and regional e-GIFs, with cognisance of the South African legislation and technical, social and political environments. The conceptual model is an enterprise model on an abstraction level suitable for strategic planning.

Quick Abstract

ERP systems are widely used by large enterprises for managing functional areas of the enterprise. However, recently ERP systems have also been introduced to the small enterprise market. ERP systems are now considered an important small enterprise management aid that may contribute to the sustainability and growth of the small enterprise. Although there are several acceptance factors that may impact on the acceptance of ERP systems, limited research has been done to understand the acceptance of ERP systems by small enterprises. This paper addresses this gap by considering the strategic, business, technical and human factors that influence the acceptance of ERP systems in small manufacturing enterprises in South Africa. The consultative list of acceptance factors flowing from this research may guide future initiatives aiming to ensure the acceptance of ERP systems by small manufacturing enterprises.

Quick Abstract

Cloud computing is changing the IT delivery model to provide on-demand self-service access to a shared pool of computing resources (physical and virtual) via broad network access to offer reduced costs, scalability, flexibility, capacity utilization, higher efficiencies and mobility. In many instances cloud computing builds on the capabilities of a virtualized computing infrastructure enabling multi-tenancy, scalability and a highly abstracted cloud model. Even though cloud computing provides compelling benefits and cost-effective options for IT hosting and expansion, security of applications and data remains a number one business objective. It is therefore essential to ensure adequate security not only for cloud computing, but also for the underlying technologies enabling cloud computing. Management should understand and analyse risks in order to safeguard systems and data. The focus of this paper is on mitigation for virtualization security risks as a fundamental step towards secure cloud computing environments.

Quick Abstract

Organisations are faced with a number of challenges and issues in decentralised, multiple-server, physical, non-virtualized IT environments. Virtualization in recent years has had a significant impact on computing environments and has introduced benefits, including server consolidation, server and hardware utilization and reduced costs. Virtualization’s popularity has led to its growth in many IT environments. This paper provides an overview of the IT challenges in non-virtualized environments and addresses the question of whether virtualization provides the solution to these IT challenges.

Quick Abstract

This paper presents relevant interoperability approaches and solutions applied to global/international networked (collaborative) enterprises or organisations and conceptualise an enhanced enterprise interoperability framework. The paper covers several key aspects including how holistic approaches of architecting principles, standards and semantics contribute to the development of an interoperability framework that can be flexibly used for interoperable complex systems, particularly ICT, that support global enterprises including organisations from multiple countries, e.g. European and African organisations. This proposed comprehensive approach of interoperability covers not only technical aspects, but also semantics alongside organisational and cultural aspects. The use of systems engineering thinking and architecting for achieving interoperability of complex systems is suggested.

Quick Abstract

Metamodels are abstractions that are used to specify characteristics of models. Such metamodels are generally included in specifications or framework descriptions. A metamodel is for instance used to inform the generation of enterprise architecture content in the Open Group’s TOGAF 9 Content Metamodel description. However. the description of metamodels is usually done in an ad-hoc manner with customised languages and this often results in ambiguities and inconsistencies. We are concerned with the question of how the quality of metamodel descriptions, specifically within the enterprise architecture domain, could be enhanced. Therefore we investigated whether formal ontology technologies could be used to enhance metamodel construction, specification and design. For this research, we constructed a formal ontology for the TOGAF 9 Content Metamodel, and in the process, gained valuable insight into metamodel quality. In particular, the current TOGAF 9 Content Metamodel contains ambiguities and inconsistencies, which could be eliminated using ontology technologies. In this paper we argue for the integration of formal ontologies and ontology technologies as tools into metamodel construction and specification. Ontologies allow for the construction of complex conceptual models, but more significant, ontologies can assist an architect by depicting all the consequences of a model, allowing for more precise and complete artifacts within enterprise architectures, and because these models use standardized languages, they should promote integration and interoperability.

Quick Abstract

The enterprise architect is dependent on the functionality of the enterprise repository to define and maintain the enterprise architecture. Two of the specific functionalities are typical ‘warehouse’ related functionalities. The one requirement is to integrate multiple business process reference models as source models, similar to the reuse of data from different sources in a data warehouse environment. The second requirement is the flexible visualization of business process models that has a ‘slice-and-dice’ flavour as used in the data warehouse domain. By means of analogical reasoning, our research investigates using the theoretical foundation of the data warehouse domain to contribute to the definition of an enterprise repository framework. Based on the similarities found, an enterprise repository framework is derived.
