- Description: Cloud computing is a relatively immature computing paradigm that could significantly benefit users. Cloud computing solutions are often associated with potential benefits such as cost reduction, less administrative hassle, flexibility and scalability. For organisations to realize such potential benefits, cloud computing solutions need to be chosen, implemented, managed and governed in a way that is secure, compliant with internal and external requirements and indicative of due diligence. This can be a challenge, given the many concerns and risks commonly associated with cloud computing solutions. One cloud computing solution that is being widely adopted around the world is cloud-based email. One of the foremost adopters of this cloud computing solution is higher education institutions. These higher education institutions stand to benefit greatly from using such services. Cloud-based email can be provisioned to staff and students at these institutions for free. Additionally, cloud service providers (CSPs) are able to provide a better email service than some higher education institutions would be able to provide if they were required to do so in-house. CSPs often provide larger inboxes and many extra services with cloud-based email. Cloud-based email is, therefore, clearly an example of a cloud computing solution that has the potential to benefit organisations. There are however, risks and challenges associated with the use of this cloud computing solution. Two of these challenges relate to ensuring conformance to internal and external (legal, regulatory and contractual obligations) requirements and to providing a mechanism of assuring that cloud-based email related activities are sound. The lack of structured guidelines for assuring the conformance of cloud-based email is putting this service at risk at higher education institutions in South Africa. This work addresses this problem by promoting a best practice based approach to assuring the conformance of cloud-based email at higher education institutions. To accomplish this, components of applicable standards and best practice guidelines for IT governance, IT assurance and IT conformance are used to construct a framework for assuring the conformance of cloud-based email. The framework is designed and verified using sound design science principles. The utility and value of the framework has been demonstrated at a higher education institution in South Africa. This framework can be used to assist higher education institutions to demonstrate due diligence in assuring that they conform to legal and best practice requirements for the management and governance of cloud-based email. This is a significant contribution in the relatively new field of cloud computing governance.

- Description: In the South African Social Security Agency (SASSA) Annual Report of 2011/2012 it is stated that there were more than 15 million social grants paid out to needy beneficiaries of which 10 927 731 were Child Support Grants. A major challenge that is continually being addressed is the management and administration of these grants. In particular, the focus is on service delivery and zero tolerance to fraud and corruption. SASSA has made various attempts to address these issues, such as the rollout of biometric smart cards in 2012. This research endeavour attempts to discover whether a framework can be designed where necessary factors are taken into consideration to provide for an efficient social grant application and delivery process that uses biometrics. The framework aims to suggest improvements in the use of biometrics for the social grants. Seeing that biometrics in this case is used as a technology to improve a system involving humans, this study followed a Design Science approach and made use of a case study to collect the data required for the study. Literature studies reviewed the fields of social grants and biometrics. The challenges and lessons learnt from current implementations of social grants and biometrics within the South African context and further abroad were also relevant for the study. The framework that resulted from the above was evaluated for validity and applicability after which a modified framework is presented. The research concludes with specific implementation guidelines as well as areas for future research.

- Description: New innovative products are being designed while the user interface of existing products is constantly being revamped to give them a new look. All this is an effort to bring a satisfactory interacting experience for the user. However, in most cases users do not feel that they experience that benefit. The introduction of a new product, or the enhancement of the functionality and user interface of an existing product, often faces criticism and brings resistance to the acceptance and usage of the product by the users. Therefore, the change in user interface or introduction of new products does not only affect the business processes but also the lifestyles of the users, as well as their overall user experience. One of the most important components for the success of any product is a positive user experience. User experience refers to the subjective feeling of the user that results from their interaction or intention to interact with a product in order to perform a specific task in a specific environment. When the user interface and functionality of a product match the expectations of the users and make the users effective and efficient, feel safe and attain some level of self-worth from using or possessing the product, their interaction with the product becomes more satisfactory. User experience practitioners are in agreement that a change to the user interface influences the user experience of the people when interacting with the product; hence it affects change in the user experience of the people. A vast body of literature exists on the methods for evaluating user experience as well as on the principles that are aimed at guiding the design of products for a positive user experience. However, there is a lack of a means to manage this change in user experience that results from the changes in the features of the user interface or the product functionalities. This inadequacy opens up the potential for integrating change management principles in order to manage user experience. However, existing change management principles do not address the user experience aspects when managing change. Following the above premise, this study focused on the development of a model for managing user experience: the User Experience Management Model (UXM2). The UXM2 infers its components from the disciplines of user experience and change management. Its uniqueness is seated in its people-centred approach that aims to effect a free-will change in the individuals towards a long-term positive user experience. The proposed model further aims to promote the voluntary acceptance of a product, which is contrary to the mandatory change that is guided by the policies of the organization, as discussed in the study. The UXM2 was developed from a thorough argumentation of literature on user experience and change management. The components that were required for development of the model were identified from literature, and were evaluated for their relevance by means of academic publications in subject domain international conferences. The academic publications underwent double-blind peer review with subject domain experts. The model was evaluated for its relevance and potential applicability through interviews and discussions with subject domain experts. The subject domain experts consist of user experience practitioners and academic professionals in the domain of HCI. The subject domain experts also evaluated the model by means of an evaluation tool comprising of a Likert scale rating of the proposed components and related activities for managing user experience. The target users of the UXM2 are user experience practitioners and product developers who aim to promote a sustainable long-term positive user experience for the people interacting with their products. The UXM2 is aimed at being used for the design of products that are meant for institutional use, personal use, mandatory use and optional use. It is believed that adoption of the UXM2 will promote acceptance of the product by users, with an associated sustainable positive long-term user experience.

- Description: The public higher education sector in South Africa is governed by an act of Parliament which defines the governance organs and mechanisms required within institutions and the sector. This doctoral thesis begins by contextualising ICT governance within the levels of systemic governance in South Africa that have relevance to this study. It then continues by advancing the understanding of the state of Information and Communication Technology (ICT) governance in public higher education institutions in South Africa by investigating the level of pervasiveness, the level of ICT process maturity and the alignment of ICT to the institutional processes within these institutions. Subsequently, this thesis results in the production of a contextually appropriate value framework that contributes towards an understanding of the need for the improvement of ICT governance. A survey of the extant literature on governance, ICT governance, and the frameworks and standards associated with governance indicates that the methodological approach currently favoured in ICT governance research is predominantly interpretive and based on surveys and interviews. This study leans towards a Design Science approach paradigm using surveys for the qualitative data collection process. The empirical research data was gathered from the highest ranking ICT officers at public higher education institutions in South Africa. This study makes contributions on a number of levels – from the first known measurement of ICT pervasiveness within the context of higher education, to the measurement of ICT process maturity and the measurement of the alignment of ICT and institutional processes, to the design of a value framework that breaks down governance into layers indicating which governance organs are appropriate at the relevant layers and which governance mechanisms can be used to address governance at each layer of governance. This study therefore makes a contribution to the ICT domain for development research by demonstrating praxis for the improvement of ICT governance implementation in the public higher education sector in South Africa. This study makes both method design and practical contributions to the ICT body of knowledge at various stages of the research process. These contributions include reflection on and analysis of the data gathering approaches that occur within the public higher education sector and in the complex environment of institutional autonomy and academic freedom; the use of Agency Theory to support the ‗governance intent‘ transfer between the layers of governance in the value framework and the synthesis of the improvement of ICT governance with value creation. The findings of this study further contribute to an understanding of the dynamics and interrelatedness of aspects of governance and management, while making a contribution to theoretical research by extending practical and empirical understanding of the ICT governance environment in the public higher education sector in South Africa.

Development of a creep sample retrieval technique and friction weld site repair procedure

- Description: The remnant life monitoring of creep loaded high temperature and pressure components in power stations is critical to ensuring their safe and cost effective operation as failures can have severe consequences. Effective creep life condition monitoring allows for optimising component life predictions and subsequent plant maintenance decisions. In South Africa many power generation stations have been in operation well beyond their 30 year design service life, as such knowledge of the remnant creep life of high temperature and pressure components, such as steam pipelines, becomes of utmost importance. Techniques for the remnant creep life assessments of critical high temperature and pressure components must therefore be as effective as possible. The common and well accepted in-situ inspection technique for assessing creep damage in steam pipes is by the metallographic replication technique. The technique is however limited to the outer surface of the pipe, without information on damage within the wall. This research will illustrate a means of obtaining a sample for creep life analysis with depth through the wall of a pipe, as wells as an alternative technique for the repair of the sample retrieval site. A sample retrieval technique was developed that would retrieve a small diameter cylindrical sample from a cored blind hole for creep analysis by visual creep void assessment or by the small punch creep test. The small punch creep test requires only a small diameter thin disc of material for testing for which its results are comparable with conventional uniaxial creep testing which requires a much larger sample of material. The smaller sample requirement of the small punch creep test therefore allows for a vastly reduced invasive sample retrieval operation and consequently smaller repair size area. Also the fact that the sample is retrieved from a blind hole is advantageous since the pipe wall is not penetrated which would require full plant shutdown. A friction welding technique was identified as an alternative to traditional arc fusion welding for the repair of the sample retrieval site, this technique being the Friction Hydro Pillar Processing technique. Friction Hydro Pillar Processing is a solid-state welding technique and as such has a number of inherent benefits over arc fusion welding as the weld is performed below the melting temperature of the material. From a process point of view Friction Hydro Pillar Processing is ideally suited for automation, has virtually no fumes generated, minimal distortion is experienced and no spatter has to be removed afterwards. The technique has yet to see industrial application and as such development of suitable process parameters was undertaken. Finally, to apply the sample retrieval and repair operations in-situ to a steam pipe in a power plant suitable equipment was developed. Existing friction welding equipment is generally bulky workshop based equipment and is unsuitable for on-site work due to its size and weight. Therefore development of dedicated equipment was required to enable Friction Hydro Pillar Processing to be applied to steam pipes within a power plant environment.

- Description: Local government is at the forefront of engagement between the government and South Africa’s people, delivering basic services to communities. Following the transition to a democratic government in 1994, the country was demarcated in a manner that provides complete coverage by local government. Annually, managing the administration of service delivery implementation at local government level costs the country many billions. Much of the revenue used by local government in providing services is derived from income from sale of basic services and property rates, augmented by allocations from national and provincial government, equitably shared amongst municipalities. Local government has autonomy in its operations, but is strictly governed by a collection of cascading legislation, introduced to protect the interests of the people. The primary objective of the research was to investigate the efficacy of budget expenditure in local government, in particular the City of Cape Town as a metropolitan municipality. With an annual budget approaching R30 billion, the aim was to establish how the budget was determined and allocated to the service menu provided by the City, and to investigate whether better methods of allocating expenditure could be developed. A mixed research methodology was followed, relying on quantitative methods for analysing survey data statistically, while providing for detailed qualitative methods in interviewing and studying the specific case in detail. The theoretical perspective most suited to this research was found to be that of pragmatism, for its flexibility of interpretation, practicality and space for multiple perspectives. A constructivist epistemology was adopted to provide for the interplay between object and subject in constructing meaning. This research focused on examination of applicable legislation, secondary data in reports, and statistical analysis of opinion surveys of municipal officials involved in budgeting at different levels and interviews with key stakeholders. The findings indicate that budget allocation can be improved upon in a number of ways, despite complying with a myriad of restrictive and onerous regulations applicable to local government. It was found that the administration is fragmented in its operations and that the structure of necessity favours isolated service delivery rather than integration. Further, that compliance impacts negatively on time spent in planning and pursuit of strategic intent to the extent that Reporting often becomes a more important deliverable than basic services. The size of the City hinders common understanding, and introducing any change in political vision requires particular attention.

- Description: The public healthcare sectors within developing nations face a lot of challenges because of constrained resources available to them. The South African public healthcare sector is no different. Although it serves the majority of the South African population, most of the financial resources are directed towards the private sector, which serves very few individuals when compared to the public healthcare sector. Apart from that, other challenges that the National Department of Health has to deal with include the lack of sufficiently trained healthcare employees who can work on the different levels of the public healthcare sector, as well as the burden of diseases such as HIV and Aids, tuberculosis and other chronic diseases. In order to improve service delivery, the National Department of Health is introducing Information and Communications Technology interventions that can increase efficiency and reduce costs, thereby improving the quality of service delivery. This research delivers an m-health application user experience framework to be proposed to the National Department of Health in South Africa, in order to assist in scaling up of m-health applications. The m-health applications that can benefit the South African population if scaled up successfully include those that can be used in remote data collection, treatment and compliance, accessing patients records, remote monitoring, communication and training for healthcare workers and applications that can be used for education and awareness. The study focused on three domains: the Human-Computer Interaction domain, public healthcare domain and Health Informatics domain. The proposed framework was realized by investigating mobile user experience components, mobile health requirements and the South African public healthcare domain components that contribute to the m-health user experience framework. This research was conducted through the interpretivist philosophy. Due to the exploratory nature of the study, an application of qualitative methodology was used. The conceptual theoretical framework was validated through a single case study approach by m-health user experience experts, who reside in South Africa. Data were analysed inductively. An m-health user experience framework was provided at the end of the study. An m-health user experience framework can assist the National Department of Health to look into design issues, address m-health requirements and put the domain needs in place, thus enabling the Department to successfully scale up implementations of m-health applications nationwide.

- Description: The public healthcare sectors within developing nations face a lot of challenges because of constrained resources available to them. The South African public healthcare sector is no different. Although it serves the majority of the South African population, most of the financial resources are directed towards the private sector, which serves very few individuals when compared to the public healthcare sector. Apart from that, other challenges that the National Department of Health has to deal with include the lack of sufficiently trained healthcare employees who can work on the different levels of the public healthcare sector, as well as the burden of diseases such as HIV and Aids, tuberculosis and other chronic diseases. In order to improve service delivery, the National Department of Health is introducing Information and Communications Technology interventions that can increase efficiency and reduce costs, thereby improving the quality of service delivery. This research delivers an m-health application user experience framework to be proposed to the National Department of Health in South Africa, in order to assist in scaling up of m-health applications. The m-health applications that can benefit the South African population if scaled up successfully include those that can be used in remote data collection, treatment and compliance, accessing patients records, remote monitoring, communication and training for healthcare workers and applications that can be used for education and awareness. The study focused on three domains: the Human-Computer Interaction domain, public healthcare domain and Health Informatics domain. The proposed framework was realized by investigating mobile user experience components, mobile health requirements and the South African public healthcare domain components that contribute to the m-health user experience framework. This research was conducted through the interpretivist philosophy. Due to the exploratory nature of the study, an application of qualitative methodology was used. The conceptual theoretical framework was validated through a single case study approach by m-health user experience experts, who reside in South Africa. Data were analysed inductively. An m-health user experience framework was provided at the end of the study.
