Item Supply chain management practices, supplier performance and supply chain resilience in the South African public sector(Vaal University of Technology, 2020-10) Mugwenhi, Shephard; Bhadury, J., Prof.; Mafini, C., Prof.The most important decisions that direct the operations of a nation are made in the public sector. The public sector performs the duty of facilitating the efficient and sustainable delivery of goods and services to the general public. In South Africa, public sector institutions have failed to fulfil their role of providing effective services, and this failure has been attributed to corruption and other inconsistencies inherent within supply chain management (SCM) transactions occurring between government and its suppliers. To streamline SCM, various legislative pieces such as the public SCM Policy Framework, the Preferential Procurement Policy Framework (PPPF) and the Broad-Based Black-Economic Empowerment (BBBEE) Act, among others were implemented in tandem with a host of other interventions. However, the challenges linked to public SCM continue to this day and the intended outcomes are yet to be fully realised, thereby negatively impacting on the effective delivery of services by the public sector. This study investigated the relationship between SCM practices, supplier performance and supply chain resilience in the South African public sector. The study is premised on the need to investigate how SCM practices may be applied to improve the effectiveness of supplier performance, and hence the resilience of the public supply chain in South Africa, in light of the numerous challenges faced by the sector. This study followed a quantitative method in which a cross-sectional survey was applied to collect data to test the relationships between seven SCM practices (supply chain collaboration, supply chain synergies, supply chain innovation, information sharing, information quality, supply chain design, supply chain integration), supplier performance and supply chain resilience. A structured survey questionnaire was developed using adapted measurement scales and administered to 333 SCM professionals recruited from public sector organisations based in the Gauteng Province. The data collected were analysed using the Statistical Package for Social Sciences (SPSS Version 25.0) and the Analysis of Moment Structures (AMOS Version 25.0) statistical software. The actual data analysis techniques applied included descriptive and inferential statistics and hypotheses were tested using structural equation modelling. The results of the study showed that three SCM practices, namely collaboration, innovation and integration exerted a significant positive influence on supplier performance. However, supply chain synergies, information quality and supply chain design were statistically insignificant. Moreover, information sharing exerted a significant negative influence on supplier performance. In turn, supplier performance exerted a significant positive influence on supply chain resilience. The study contributes in various ways to both public SCM theory and practice. Theoretically, it provides information on how the SCM dimensions considered in this study, which are supply chain collaboration, synergies, innovation, information sharing and quality, design, and integration are linked to supplier performance and supply chain resilience within the public sector in South Africa. Given the limited evidence of previous studies of this nature in the South African public sector, the results are an essential addition to the existing body of literature within the public SCM context in developing countries such as South Africa. From a managerial standpoint, the study provides information on which SCM practices deserve attention in the efforts to improve the performance of suppliers, and how the performance of suppliers can be harnessed to enhance the resilience of the public supply chain. Hence, the study offers an important diagnostic framework through which the SCM challenges facing the public supply chain in South Africa can be addressed.Item Supply chain risk mitigation strategies in the electrical energy sector in South Africa(Vaal University of Technology, 2018-08) Jonathan, Ellsworth Chouncey; Bhadury, J., Prof.; Mafini, C., Prof.Interferences to supply chains, regardless of whether they are regular, unplanned or intentional, are progressively distorting supply chain execution. Given that such disruptions are probably not going to diminish, for the time being, supply chain risk mitigating solutions will assume an undeniably critical part of the management of supply chains. This research acknowledges the existence of an extensive variety of approaches to mitigate risks across supply chains, yet argues that most methodologies may not be reasonable if the culture of an organisation does not support them. Supply Chain Risk Management (SCRM) has rapidly become of significance to the world economy. Though the supply of electrical energy in Southern Africa affects the economies of nations around the globe, it has received too little consideration from the literary community. The focus of this thesis is to expand the field of SCRM by analysing how different risk assessment and management concepts and practices are comprehended, construed and employed through the region. The majority of developed supply chain management and risk management models are currently entrenched in the US and Europe. Consequently, this research is of high significance since its essential aim was to investigate these concepts and models, in particular, one focused on Africa. This approach enabled the thesis to examine and test components related to SCRM, such as risk categories, risk assessment and risk strategies, in the electrical energy sector in South Africa. The study in this manner offers knowledge that was not otherwise accessible in earlier research. In pursuit of meeting the requirements of the research questions, the supply chain department in the electrical energy supplier was researched. This study adopted the non-probability sampling approach utilising the purposive sampling technique to choose the sampling components from the target population. Data was collected by way of conducting semi-structured interviews and researcher observation, as well as additional documentation in various forms was collected. Interviews were transcribed and evaluated in conjunction with additional data collected during meetings and triangulated using researcher observation. Data interpretation and codification thereof was done using ATLAS.ti 8 by which, twenty-five themes emerged from this study. Supply chain risks comprise value streams; information and affiliations; supply chain activities; and external situations. Among these, information and relationships risks were found to produce selfupgrading risk loops, thereby generating consequent risk impacts after disturbances. To mitigate these risks, the case firm must engage in local and international supply chain implemented strategies, such as building a stable supply chain network, leveraging supply chain information, leveraging outsourcing contracts and developing supply-chain risk collaboration partnerships, although the level of implementation depends on the business context. Among the ten identified themes, building a stable supply chain and developing supply chain collaboration strategies can be useful in strengthening both robustness and resilience in supply chain risk management. Customer orientation had positive impacts on all themes, but disruption orientation and quality orientation influenced only certain types of strategies. The study makes ten recommendations, which can be implemented by the case firm; the results of the interviews are evidence that all the tools are available. The thesis concludes with a summary of overall findings and areas for further research are also highlighted.
