- Description: Effectively managing information technology (IT) resources has become a significant concern for organizations, both large and small, as they conduct their business operations. IT governance, characterized as the decision-making process ensuring alignment with business strategy, optimal utilization of IT assets, and the effective management of risk and organizational value, plays a crucial role in addressing this concern. Within this landscape, an IT shared services model emerges as a strategic approach to develop, maintain, and deliver innovative services, thereby enhancing effective and efficient service delivery. This model is perceived to not only innovate services but also to liberate other departments, enabling them to focus on their core competencies. This study positions IT governance as a comprehensive umbrella process that guides the implementation of IT shared services. A well-guided implementation of IT shared services is anticipated to contribute significantly to the success of IT projects, ultimately benefiting all activities supported by these services. The implementation of shared IT services in academic tertiary institutions is not well documented or discussed. This study thus is done in such an academic context. This study focuses on developing a strategic framework for the implementation of IT Shared Services at tertiary education providers. The specific case study used for the development of the strategy is Nelson Mandela University. The scope of the project focuses on the development, proposal, and expert review of a strategy for implementing IT shared services effectively in alignment with Governance Practices. The practical implementation of the strategy falls beyond the scope of this study. , Thesis (MPhil) -- Faculty of Engineering, the Built Environment and Technology, School of Information Technology, 2024

- Description: The use of Computer Aided Software Engineering (CASE) tools for teaching object-oriented systems analysis and design (OOSAD) has many potential benefits, but there are also several problems associated with the usage of these tools. A large portion of these problems relate to the usability and learnability of these tools. Learnability is one of the most important attributes of usability and refers to the capability of the system to enable the user to learn its application. The main research question that this study aims to address is “How can the learnability of OO CASE tools for computing education in South Africa be evaluated?”. In order to answer this question several frameworks for evaluating CASE tool usability and learnability were investigated. One of these frameworks, as proposed by Senapathi, was selected as being the most appropriate for evaluating CASE tool learnability for computing education. This framework maintains that the learnability of a CASE tool is dependent on context of use factors such as the tool used, as well as user characteristics such as gender. The primary aim of this research was thus to validate Senapathi's framework for CASE tool learnability in a South African context. A secondary aim of the research was to extend the implementation of the framework in order to enable the comparison of two CASE tools and to support the inclusion of other user characteristics. An experiment was performed at the Nelson Mandela Metropolitan University (NMMU) in 2006. The participants recruited for this experiment were second year computing students at NMMU. During this experiment, the learnability of two OO CASE tools, namely IBM's Rational Software Modeller and Microsoft's Visio, was evaluated and compared. The quantitative and qualitative results supported Senapathi's results and showed that her framework could be used to evaluate CASE tool learnability and could be adapted to evaluate two CASE tools. The results also showed that the majority of the participants rated the learnability of Microsoft Visio higher for both tasks and that the main reasons participants preferred Visio was due to its simplicity, familiarity and recoverability.
