Item The use of cloud computing and its effect on organisational performance in the public sector(University of the Witwatersrand, Johannesburg, 2024) Naidoo, Wesley; Mudau, NormanCloud computing is changing how public sectors work, making things faster and better. This paper looks at how cloud computing affects how well public organisations do their jobs, considering both money-related and other benefits. Cloud computing is essential for public services because it can make them work better and give better services to people. Nevertheless, understanding how it helps is difficult, especially with the public sector's unique rules and challenges. Cloud computing is one of the new technologies that has gained prominence in recent years. Even though the value associated with this technology has been widely researched, especially for large enterprises, the rate at which public sector entities use cloud computing remains low. This research sought to explore and describe the use of cloud computing and its effect on organisational performance in the public sector. To understand the problems, factors influencing the use of cloud computing and its use on organisational performance were investigated, considering both financial and non-financial factors. The study utilised the extended Technology Organisation Environment (TOE) and Resource-based view (RBV) framework (Gangwar,2017) as the theoretical lens to understand the cloud computing phenomenon. Methodologically, this study employed online surveys administered through the Qualtrics online survey platform to gather data. These surveys sought to extract invaluable insights into the use of cloud computing and its effect on organisational performance in the public sector. The main factors identified as necessary in using cloud computing are human resources, business resources, technology resources, change management, leadership, policy and regulation, customer performance, operational performance, and financial performance. The model was tested through a cross-sectional design using data collected from a sample (N=400) of individuals employed in the public sector in South Africa using matched data collected over a period of approximately 16 weeks apart. Structural equation modelling with AMOS was used for all model testing. This study applied a complex approach to data analysis using descriptive statistics, correlation analysis, confirmatory factor analysis, and multiple regression through structural equation modelling to provide an analysis of the various variables identified. The iii research showed significant relationships between cloud computing use and leadership, policy and regulation, human resources, technology and business resources. This confirmed the first objective of understanding the factors that influence the use of cloud computing in the public sector in South Africa. The following significant result showed that this is a new contribution, as previous studies measured non-financial performance as a single item instead of expanding it to include customer, operational, and financial performance. The testing of the model thus contributes to developing a theory that explains the mechanisms through which cloud computing influences organisational performance and extends our understanding of the organisational conditions under which cloud computing usage is most important to performance. The empirical results confirm that cloud computing use is vital to affect organisational performance in the public sector. The study further contributes much-needed evidence of the relationships addressed by the influence of cloud computing on a holistic perspective of organisational performance, encompassing operational, customer, and financial aspects. This study aims to provide industry practitioners with practical insights and actionable strategies to justify investments in cloud computing systems and to improve how cloud systems are used.Item The perceived impact of Emerging Technologies on Cybersecurity in the South African financial sector(University of the Witwatersrand, Johannesburg, 2022) Philips, Denzil; Pillay, KiluThis study is based on the investigation of what is the perceived impact of emerging technologies on cybersecurity in South African financial institutions. New and emerging technologies have made significant advancements in many industries that can be very disruptive in nature, and the majority of these technologies have changed the cyber threat landscape as well. These include, among other things, cloud computing, artificial intelligence, and machine learning. The study offers insight into how these emerging technologies affect the cybersecurity of financial institutions in South Africa. The study consisted of Information technology risk and cybersecurity individuals. The sample size of 11 individuals was seen as sufficient based on the spread across the financial sector and the experience within the various industries. The individuals were from banks, insurers and market infrastructures within the South African financial sector. The sample focused on key financial institutions specifically banks, insurers, and market infrastructures, based in different provinces in South Africa such as Johannesburg and Cape Town where the impact could be systemic in the country. A qualitative study was adopted by the researcher based on systems theory to determine the relationship between the adoption of emerging or new technologies and the impact it has on cybersecurity. There were various responses from the different institutions, focusing on the adoption of emerging technologies, the effects of this adoption on the cybersecurity environment, the risk and vulnerability management processes, and the ability to adapt and respond to new cybersecurity risks introduced by emerging technologies. The results of the study found that there is a clear link between the adoption of emerging technologies and the increase in cybersecurity requirements with emerging technologies significantly impacting the cybersecurity domain/functioItem Leadership and the adoption of cloud computing for enterprises in Johannesburg(University of the Witwatersrand, Johannesburg, 2022) Lephoto, Palesa Irene; Matshabaphala, M.D.JCloud computing is extensively adopted by many enterprises globally. South African enterprises have resisted the shift to cloud computing adoption despite there being extensive potential for organisations. The contribution of this study was to examine the factors that influence leadership to adopt cloud computing as part of digital transformation strategy for their enterprises in Johannesburg, Gauteng Province, South Africa. The qualitative general research design was used to investigate the perceptions leaders have about cloud computing which translates into slow adoption of cloud computing. The data was collected through interviews from participants holding leadership positions in their respective organisations. The findings were analysed and discussed using an inductive thematic analysis approach to identify and code emergent themes within the data. The findings indicated that multiple factors influence leadership to adopt cloud computing for their enterprises. Understanding the cloud computing concept includes the drivers and barriers halting the adoption, the characteristics and traits of the leader, and the organisational factors contributing to the prospect of embracing cloud adoption. Despite the significant benefits of cloud, adoption in Johannesburg enterprises experiences challenges and the enterprise leaders still have reservations in fully adopting cloud for their organisations due to both macro and micro limitations
