- Description: One problem faced in the Information Systems domain is that of poorly maintained, poorly documented, and/or unmanageable systems, known as Legacy Information Systems (LISs). As a result of the everchanging web development landscape, web applications have also become susceptible to the challenges faced in keeping up with technological advances, and older applications are starting to display the characteristics of becoming Legacy Web Applications (LWAs). As retaining business process support and meeting business requirements is often necessary, one method of recovering vital LWAs is to modernise them. System modernisation aims to recover business knowledge and provide an enhanced system that overcomes the problems plagued by LISs. When planning to modernise an LWA, guidance and support are essential to ensure that the modernisation exercise is performed efficiently and effectively. Modernisation methodologies can provide this required guidance and support as they provide models, tools and techniques that serve as guiding principles for the modernisation process. Although many modernisation methodologies exist, very few offer a comprehensive approach to modernisation that provides guidelines for each modernisation phase, tools to assist in the modernisation and techniques that can be used throughout. Existing methodologies also do not cater for cases that include both the LWA and migration to modernised web-specific environments. This research study aimed to investigate modernisation methodologies and identify which methodologies, or parts thereof, could be adapted for modernising LWAs. Existing methodologies were analysed and compared using the definition of a methodology, as well as other factors that improve the modernisation process. Modernisation case studies were reviewed to identify lessons learned from these studies so that these could be considered when planning an LWA modernisation. The ARTIST methodology was the most comprehensive modernisation methodology identified from those researched and was selected as the most appropriate methodology for modernising an LWA. ARTIST was modified to the mARTIST methodology to cater for web-based environments.mARTIST was used to modernise an existing LWA, called OldMax, at an automotive manufacturer, anonymously referred to as AutoCo, to determine its ability to support the modernisation of LWAs. Additional tools and evaluation methods were also investigated and used in place of those recommended by ARTIST, where deemed appropriate for the modernisation of OldMax. Limitations set by AutoCo on the hosting and technical environments for the modernised application also required ARTIST to be adapted to better suit the use case. The steps taken during this modernisation were documented and reported on to highlight the effectiveness of mARTIST and the tools used. The result of this modernisation was that the modernised web application, ModMax, was evaluated to determine the success of the modernisation. The modernisation of OldMax to ModMax, using the mARTIST methodology, was found to be successful based on the criteria set by the ARTIST methodology. Based on this, mARTIST can successfully be used for the modernisation of LWAs. To support future modernisations, an evaluation method for determining technical feasibility was developed for LWA, and alternate tools that could be used throughout modernisation exercises were recommended. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2024

- Description: Information Technology is the application of technology to solve business or organisational problems on a broad scale. The COVID-19 pandemic has brought a standstill to many businesses, including that of the automotive industry, where production was brought to halt, car sales plummeted and automotive industry employees were forced to work remotely. This study sought to understand the measures needed to be taken by the automotive industry in preparation for a pandemic. This study followed a deductive approach and the use of surveys was selected as a data collection tool. At the time of the study, the study population was permanently employed automotive industry employees based in Nelson Mandela Bay, working in administrative departments. These employees had access to ICT tools provided by the targeted company. The study aimed to investigate the IT measures needed by the automotive industry in preparation for a pandemic. More specifically, the study investigated IT infrastructure, financial support and communication, as well as IT skills and training, needed by the automotive industry in the Nelson Mandela Bay area for successful remote working. The empirical results were obtained from 127 automotive industry employees. The aim was to determine the extent of Remote Work Assessment in the Nelson Mandela Bay automotive industry and whether IT infrastructure, Communication, Financial support, IT skills, IT personnel support and IT training were the strongest determinants of measuring IT needs in preparation for a pandemic. The findings of the study indicated that IT infrastructure, Communication, IT skills, IT personnel support and IT training were important determinants of Remote Work Assessment. The study also revealed that only financial support was deemed as an insignificant determinant of Remote Work Assessment. Furthermore, recommendations were made to automotive industry leaders and management to facilitate improved working conditions with government. This can lead to significantly better forecasting and vi measurement of IT needs for future pandemic preparation in the automotive industry in the Nelson Mandela Bay area. , Thesis (MA) -- Faculty of Business and Economic Sciences, 2022

- Description: This study investigated information communication technology for personal information management by the University of Fort Hare (UFH) students in the Faculty of Social Science and Humanities (FSSH). The objectives were to: find out which information communication technology applications and tools the students often use to acquire personal information; determine at what stage the students often experience a high influx of personal information and how to cope with the technology, and establish the challenges the students encounter when using information communication technology to manage personal information. The aim was to assess information communication technology for personal information management by UFH students in the FSSH. A sample of sixty respondents was randomly selected to represent a large population hoping that the results could be generalized to all FSSH students and make predictions. A quantitative research approach was chosen, utilizing the survey design and the Theory of Planned Behavior because of attitudes, behavioral control, and subjective norm. The findings reveal that 55percent of the students prefer to use portable devices, laptops to be specific to access and store information. Even though there are many search engines, 93percent of the students often use Google to search and access academic purposes on the internet. Their primary reason is that it is easy to access, download, and store information from Google. It was also established that 26percent of the students face challenges such as slow internet or damaged computers, unavailability of Wi-Fi, and crowded computer labs. This hindered their learning process. As a result, out of desperation, racing against time to submit assignments, students end up committing plagiarism. Moreover, the study's findings showed that 50percent of the students encounter information overload before they write their exams because, at this point, they are working towards collecting as much information as possible to be prepared for the exams. Furthermore, the study affirmed that 57percent of the students agree that possessing computer skills helps students in their academic journey and confirmed that students from previously disadvantaged backgrounds lack of computer skills negatively affect their academic performance. They need a quantum leap to acquire computer skills imperative for their information access, engagement, consumption, and knowledge production. , Thesis (MLIS) -- Faculty of Humanities, Social Science and Humanities, 2021

- Description: The South African Revenue Service (SARS) is an autonomous agent that was established to collect taxes on behalf of the state. This mandate is shared across countries where the common thread of revenue collection agencies is that they all need to collect revenue, want participants within the system to act responsibly, the process to be fair and to act within the boundaries of legislation. It has become increasingly challenging for revenue collection agencies across the world to ensure tax compliance and ensure optimal revenue collection when unemployment rates are high, and the economy continues to struggle. It is a shared objective between revenue collection agencies to optimise revenue collection initiative and to narrow the tax gap. The technological advances in all sectors have grown at an exponential rate within a very short period. The WEF (2018) emphasised that the fourth industrial revolution (4IR) brings with it an era of unprecedented innovation, technical change and global connectivity. Technology has become the key driver in assisting SARS to achieve its objectives to inform taxpayers of their responsibilities, make it easy for them to comply and ensure compliance to the tax laws. The primary objective of the research study is to investigate the possible factors that could influence the future state of revenue services, develop a series of alternative scenarios, and provide the preferred future of the South African Revenue Services towards 2030. The Six Pillars of futures studies provide a theory of futures thinking that links method and tools, that is developed through praxis (Inayatullah, 2012). The Causal Layered Analysis (CLA) was the preferred research tool used in this study to deepen the future analysis. Emphasis was placed on scenario planning and the creation of alternative futures for the South African Revenue Services towards 2030. The drivers of change that impacted the economy were identified and how it can be utilised to close the tax gap. SARS has been a victim of seizure where the destabilising of corporate governance and efficiency was the core objective. It is therefore important to understand the past and present to enable better planning. This paper aims to better understand the disruptors to industry and the opportunity to improve efficiency and effectiveness using technology associated with the 4IR. SARS has great potential in being globally competitive with other countries, if government, stakeholders and SARS leadership have a shared vision of what the future revenue services will look like, what its capabilities will be and resource availability to ensure this vision is realized. , Thesis (MBA) -- Faculty of Business and Economic Sciences , Business Administration, 2021
