Item Assessing the influence of internal environmental management systems on green packaging management, green information systems and organisational performance(Vaal University of Technology, 2021-07-26) Mahlangu, D. M.; Chinomona, E., Dr.; Hove-Sibanda, P., Prof.The effective practice of green supply chain has been a focus of both practitioners and researchers for almost a decade, mostly focusing on greenhouse effects and implementing full green supply chain control systems. However, not much attention has been given to empirical relationships between internal environmental management systems, green packaging management, green information systems adoption and organisational performance. The chief objective of this study was to assess the internal environmental management factors of the plastic packaging manufacturing organisations in Gauteng province in South Africa, mainly focusing on the three major internal environmental factors, namely pollution prevention plans, total quality management and environmental audits. Secondly, the study aimed to determine the relationship between green packaging management, green information systems and organisational performance. A positivist approach was used as this study is quantitative. A total number of 250 questionnaires were distributed to managers and employees of the chosen plastic packaging organisations. Although 250 questionnaires were distributed to the chosen organisations, only 230 were deemed to be fit for capturing due to some errors on the other 20 questionnaires. For data analysis the Statistical Package for Social Sciences (SPSS 24) was used to generate frequency tables and graphs. Furthermore, structural equation modelling (SEM) was used to generate regression weights and standard regression weights. The factor loading was also generated using SEM as well as model fitness and path co-efficiency values. A detailed research approach was followed using a sample size of 230; the results of this study show that there is a positive significant relationship between internal environmental management systems, green packaging management and green information systems. Further, it was found that most organisations that adopt green management systems are more likely to perform better than those that do not. The study also discovered that the government policies that place emphasis on green practices, not only pressurise organisations, but also help them to be strategic. Most plastic packaging manufacturing organisations usually find it difficult to operate without polluting the environment, but this study discovered that if they control their internal environmental systems, it will be easy for these organisations to adopt environmental management systems and produce green products. Also, given the changing market environments, currently most consumers prefer green products and if organisations go green this might open up new markets for their new products and enhance performance. This study examined the importance of green packaging management from the perspective of both government policies and organisational policies. The results showed that some organisations are still struggling to align their internal environmental management process with the external environment; however, the market changes are enforcing that most plastic packaging organisations start aligning their internal management systems with external systems, as it gives them opportunities towards new products and new competitive strategies that will lead to better performance. An environmental management framework was developed in this study. The framework aims to help guide plastic manufacturers with their long- and short-term strategies. In line with non-linear relationships between variables, the study recommends the following to the plastic packaging organisations: to create pollution prevention policies and strategies to improve organisational performance by eliminating pollution and avoiding penalties from the government. Pollution prevention plans, total quality management and environmental audits were used as independent variables to measure organisational performance. In line with the linear relationship between the adoption of green packaging management and organisational performance, it is recommended to the plastic packaging organisations that enterprises facing slow-moving sales growth, profitability and general performance challenges, should use green technologies as a remedy for their problems.Item Buyer-supplier commitment and competitive performance among small and medium enterprises in Southern Gauteng(Vaal University of Technology, 2020) Nwele, Uju Kingsley; Chinomona, E., Dr.; Omoruyi, O., Dr.Economic growth, job creation and improved standard of living have resulted to focus mostly on small and medium enterprises (SMEs) across the world. Hence, establishing and maintaining relationships with partners across the supply chain has become a prerequisite for achieving long-term competitive benefits in the present business competitive environment. For this reason, buyer-supplier commitment is deemed an important long-term business relationship strategy towards achieving competitive performance. Although buyer-supplier commitments can serve as the basis for the development of relational standards, unbalanced commitments, on the other hand, may become a harbinger of opportunistic behaviours. This development is inimical to continued business relationship and its consequential benefits for the SMEs’ supply chain collaborators. Guided by the theoretical lens of the social exchange theory (SET), this study examines the influence of communication, product quality, flexibility, and buyer-supplier commitments on SMEs competitive performance in southern Gauteng. Using a convenience sampling technique, the study quantitatively analysed the 396 returned questionnaires. Data analysis was conducted using the statistical package for social sciences (SPSS) version 25.0 and AMOS 25.0 for the confirmatory factor analysis and the structural equation modelling (SEM) respectively. The SEM analysis helped to confirm the suitability of the model fit as well as the positive and significant relationships of the proposed hypotheses. The analysis revealed that communication, product quality and flexibility are important variables in predicting buyer-supplier commitment as they displayed positive association with buyer-supplier commitment and the latter is significant in a firm’s effort towards achieving competitive performance. The study recommends the anchoring of SMEs strategies on commitment inorder for partners to efficiently and effectively enjoy competitive benefits. This research contributes new knowledge to the body of literature by developing a research framework on SME’s business growth and competitive performance and offered recommendations based on the study, which if implemented, could improve the economy. The study also revealed a higher relationship among the baseline constructs (communication, product quality and flexibility) which have received little or no conceptualisation in literature.Item The drivers of supply chain performance in the food retail industry in Gauteng province(Vaal University of Technology, 2018-01) Ngouapegne, Chriss Narick Mangoukou; Mafini, C., Prof.; Chinomona, E., Dr.The food retail industry is an important contributor to the economy. Buyers and suppliers in this industry work in collaboration with each other to achieve superior supply chain performance. To achieve this, they have to find ways and methods to improve it. The purpose of this study was to investigate the drivers of supply chain performance in the food retail industry in the Gauteng province. This study considers three of these drivers, namely buyer-supplier trust, buyer-supplier commitment and supply chain relationship longevity. A quantitative approach was adopted in which a survey questionnaire was used to collect data from 429 managers and staff members from food retailing firms in the Gauteng province. The study used a non-probability convenience sampling technique to select respondents. Data were analysed with the aid of two software packages, namely the Statistical Package for the Social Sciences (SPSS version 24.0) and the Analysis of Moment Structures (AMOS version 24.0). A confirmatory factor analysis was applied in examining and testing the relationships between observed constructs and their causal latent constructs while structural equation modelling was used to test the hypothesised relationships between constructs. The results of the research revealed that buyer-supplier trust, buyer-supplier commitment and supply chain relationship longevity positively and significantly influence supply chain performance. Buyer-supplier trust exerted a positive and significant influence on both buyersupplier commitment and relationship longevity. Also, the results showed that buyer-supplier commitment has a positive and significant influence on relationship longevity. The study concludes that to achieve greater supply chain performance, food retailers should expedite the levels of trust, commitment and length of relationships with their suppliers. The results of this study provide useful insights on how businesses in the food retail industry could benefit from trust, commitment and relationship longevity as well as on how to improve supply chain performance. The results of this study contribute to the existing body of knowledge by generating new information on buyer-supplier relationships. Therefore, the study is useful to buyers and suppliers in the food retail industry who wish to enhance supply chain performance and develop better relationships.Item Dynamic capabilities as determinants of supply chain performance in small to medium enterprises in the Vaal region(Vaal University of Technology, 2017-10) Lavhelani, Phathutshedzo David; Chinomona, E., Dr.; Omuruyi, O., Dr.The study investigated dynamic capabilities as determinants of supply chain performance in small to medium enterprises in the Vaal region. The study contributed to the body of knowledge addressing dynamic capabilities as determinants of supply chain performance in small to medium enterprises. The study developed a model with five hypotheses and was empirically tested. Following a positivist research paradigm, a quantitative approach as a research strategy was employed to test the proposal conceptual model. A survey was conducted with 288 participants in Vaal region using aprobability strastified sampling method to identify the respondents fitting the predetermined sample criteria. A self-administered survey was followed as a method of data collection. Topical areas, research methods and data acquiring procedures were described. Permission was sought from SME owners. Sample data from SME owners/managers in the retail, mining, construction, tourism, transport, finance / insurance, community/ personal service, manufacturing and other businesses within Southern Gauteng, specifically in the Vaal Region were collected for the final data analysis of this study. The researcher used the Statistical Package for the Social Sciences (SPSS version 23.0) to analyse data. The sample data were analysed by performing a confirmatory factor analysis (CFA) and structual equation modelling (SEM) using the AMOS 23.0 statistical analysis software. The principal finding of this study reveals that dynamic capabilities, relationship longevity and service quality have an impact on supply chain performance. The conclusions and implications of the research findings are provided, and recommendations are suggested.Item An exploration of procurement practices in the state-owned passenger rail agencies in Gauteng province.(Vaal University of Technology, 2018-12) Mkhabele, Caxwell; Chinomona, E., Dr.; Van der Westhuizen, J. P., Dr.Supply Chain Management (SCM) departments and, specifically, procurement functions, account for the largest expenditure in most organisations. However, their function has been misunderstood, undervalued, and under-capacitated, and their strategic importance not recognised. As a result, the majority of public agencies in South Africa are implementing their procurement practices poorly. The main research question of this study focused on procurement practices in the state-owned passenger rail agencies in the Gauteng province. A qualitative research method was adopted in which semi-structured interviews were employed to gather data regarding current procurement practices within the procurement function in the state-owned passenger rail agencies. Content analysis was utilised to analyse and interpret data collected from 12 procurement officials employed in the procurement functions within these state-owned passenger rail agencies in the Gauteng province. The findings of this study indicate that there are poor procurement practices within the state-owned passenger rail agencies in the Gauteng province regardless of government initiatives established to address lack of accountability, inconsistency in application of procurement policies, lack of supporting structures and fragmented processes. The detailed findings indicate that the procurement function is still regarded as an administrative function within the state-owned passenger rail agencies. Due to the procurement function still being regarded as an administrative rather than as a strategic function, the procurement function is still under-rated within the state-owned passenger rail agencies in the Gauteng province. The findings also establish that there is poor contract management during the procurement processes. Furthermore, the findings established that there is poor implementation of supplier management within multiple stages of the procurement processes in the state-owned passenger rail agencies in the Gauteng province. Due to poor procurement practices within the passenger rail agencies, eleven challenges were identified within the procurement functions. As a result of the above-mentioned challenges, this study recommends strategies that can be used to address the problems identified within the procurement functions of these state-owned passenger rail agencies in the Gauteng province.Item Exploring the factors determining ethical supply chain management in the fast-moving consumer goods industry(Vaal University of Technology, 2020-11) Chivhungwa, Tafadzwa; Chinomona, E., Dr.; Mafini, C., Prof.The application of business ethics in Supply Chain Management (SCM) activities in the business environment has attracted much-needed attention from research academics and practitioners alike in recent years. SCM activities within organisational processes are subject to various ethical principles when facilitating contractual procedures between supply chain partners. In a broader context, ethical SCM has mostly been applied to the public industry. Less attention has been directed, however, towards private businesses that seek to employ ethical compliance towards SCM processes. In view of the growing importance of ethical conduct in the private industry, the purpose of this study is to explore the factors that determine ethical SCM in the Fast-Moving Consumer Goods Industry (FMCG) in Gauteng Province. In this study, a quantitative research approach was employed to examine and test the factors that have an influence on ethical SCM in the FMCG industry within South Africa. A cross-sectional survey design was utilised to collect and test the empirical data collected from 221 purposively selected professional employees and managers in the FMCG industry in Gauteng Province. The collected data were analysed through the use of the Statistical Packages for Social Sciences (SPPS version 26.0) software and analysed using a combination of descriptive and inferential statistics. Specifically, the techniques used to analyse data include frequencies, percentages, mean scores, Exploratory Factor Analysis (EFA), t-tests, ANOVA, Pearson correlations and regression analysis. Using the EFA technique, six legal components of ethical SCM were identified. These are moral standards, transparency, professional competence, corporate governance, accountability and fairness. Three components, namely supplier assessment and monitoring, relationship commitment and supplier collaboration, were extracted in the EFA procedure. A further three personal ethics components were extracted, namely intrinsic values, honesty and integrity and skills. Descriptive statistics reveal that most managers and professional employees within the FMCG industry believe that they follow the legal aspects of SCM ethics. They also indicated that their firms are effective in managing their suppliers. The managers and professional employees in the FMCG industry also perceived that they espouse a high standard of personal ethics in their SCM activities. The results of the t-tests revealed that female respondents are more likely to adhere to personal ethics than their male counterparts. Results of the ANOVA tests revealed significant statistical differences on the race and occupational area categories of the FMCG employees that participated in this study. Under the race category, Whites and those of the Mixed race have different attitudes towards supplier collaboration when compared to other racial groups. Managers and professional employees from the procurement department have different attitudes on legal aspects when compared to those in other departments such as transport, warehouse, contract management and customer services employees. Pearson correlations revealed that connections between the constructs were either weak or moderate. Regression analysis revealed that among all legal components and personal ethics factors, only fairness significantly and positively predicted supplier management. The study recommends that the FMCG industry should recruit and develop managers and professional employees with a recruitment process that is more structural and process-driven as this promotes a unique brand of leaders that dictate sound and effective leadership processes. To maintain effectiveness amongst managers and professional employees, training remains a catalyst in increasing knowledge, skills and overall competency within the FMCG industry.Item The influence of production planning on business performance as a risk management technique in the manufacturing industry(Vaal University of Technology, 2021) Mogano, M. M. K.; Omoruyi, O., Dr.; Mafini, C., Prof.; Chinomona, E., Dr.Production planning in the manufacturing industry has previously been viewed as a less strategic function for achieving businesses’ bottom-line goals. Many companies in the manufacturing industry focus more on strategic sourcing and cost saving initiatives for financial profits and often neglect the operational planning initiatives. The purpose of this study was to examine the influence of production planning on business performance as a risk management technique. A quantitative approach was adopted for the study and a questionnaire was distributed physically and electronically to production managers, operation managers, supply chain managers and general managers; 306 respondents participated. The data obtained were analysed by means of the Statistical Packages for the Social Sciences (SSPS). Model fit and hypotheses between the relationships identified in the study were tested through the Smart PLS 3 software. Business performance was evaluated through four indicators, namely production planning, production scheduling, lead time delivery and first to market. The results of the study show that production planning has a positive impact on the production scheduling function for lean production cost saving initiatives. The study also found that production planning positively influences lead time delivery and first to market because it manages the flow of material, production and delivery to the end user. Production scheduling and first to market proved to have very significant and positive relationships with business performance. These constructs have proved to deliver a competitive advantage and also improved customer satisfaction. The findings of this study present general key strategies to improve operational efficiencies and this study can contribute to increasing the literature in lean manufacturing and production excellence.Item The influence of supply chain responsiveness, collaboration and information sharing on the performance of small to medium enterprises in a district municipality(Vaal University of Technology, 2020) Mba, Eucharia Akuoma; Chinomona, E., Dr.; Omoruyi, O., Dr.Supply chain management is becoming more complex for small- and medium enterprises (SMEs) and the need to improve performance seems to be significantly necessary. For SMEs to be efficient and effective towards minimising disruptions within supply chains, ensuring availability of resources and improving just-in-time delivery, information sharing coupled with supply chain collaboration and responsiveness are essential strategies for enhancing business performance. Therefore, this study regards supply chain collaboration, responsiveness and information sharing as major factors influencing not only SMEs performance. In this study, a quantitative research methodology was applied. Relational governance theory (RGT) provided structure to a clear understanding of information sharing among SMEs and customers. The theory highlighted that SMEs aiming to improve their performance, should adopt the style of collaborating with the right suppliers and continuously communicate with the members of the supply chains. This structure guided the researcher towards planning, implementing and evaluating the research findings. An overview of the research methodology and the techniques used in the study are presented, including the Statistical Packages for Social Sciences (SPSS version 25.0 Windows) used to analyse and determine the reliability and validity of the research instrument. Results acquired show a strong relationship between the four constructs. Confirmatory factor analysis (CFA) and structural equation modelling (SEM) results support the empirical findings, suggesting that the model fit the study. The reliability and validity of the constructs (composite reliability) and the average variance extracted sought the empirical findings that correlate the need for SMEs to employ information sharing, supply chain responsiveness and supply chain collaboration as a determinant influence on SMEs performance. The Cronbach alpha values ranges from 0.823 to 0896 and AVE results ranges from 0.500 to 0.625 respectively which indicate acceptable reliability and validity for this study. It is recommended that as focused responsiveness is critical, all efforts made by SMEs must be expanded in order to determine what constitutes desired responsiveness for individual members in the supply chain. Differentiated and highly responsive programmes for key members of the supply chain should be impartial with supply chain members oriented but less tailored approaches for lesser involved members. Enough and important information must be obtained in order to identify the member’s requirements.Item A model for supply chain risk management and operational performance in the food retail industry in Zimbabwe(Vaal University of Technology, 2019-12) Mutekwe, Le-Roy Tanyaradzwa; Chinomona, E., Dr.; Mafini, C., Prof.The importance of the food retail industry and its role in stimulating economic growth and ensuring food availability as the final actor in the food supply chain in many countries is well documented in literature. This stands true in the case of Zimbabwe, where the industry has grown tremendously to become a significant contributor to the gross domestic product through employment creation, tax contributions and infrastructural development. Despite these contributions, the industry faces challenges in the form of supply chain risks. This is primarily due to the nature of the retail supply chain in Zimbabwe where over two-thirds of the products sold are imported. This forms the basis of this study which seeks to understand how supply chain risk management in food retail firms impacts on firm operational performance. Thus, this study aimed to investigate the relationships between supply chain risk management and operational performance in the food retail industry in Harare, Zimbabwe. To achieve the study’s aim, several variables were considered; namely, supply chain risk management, supply chain risk information sharing, and supply chain risk analysis and assessment, supply chain risk-sharing mechanisms and operational performance. The study followed a quantitative research approach based on a positivist paradigm. A total of 264 food retail firm owners, managers and professional employees who possess knowledge on supply chain risk management in Harare were selected using a non-probability, purposive sampling technique. Data were then collected using a close-ended survey questionnaire which was developed using adapted measurement scales. The collected data were analysed using the Statistical Packages for Social Sciences (SPSS version 25.0) and the Analysis of Moment Structures (AMOS version 25.0) statistical software. The applied data analysis techniques included descriptive statistics and inferential statistics. Inferential statistics used two approaches, namely, Exploratory Factor Analysis (EFA) and Structural Equation Modelling (SEM). The EFA tested for the factor structure of the collected data, whereas SEM tested for both psychometric properties of measurement scales and the relationships in the proposed hypotheses. The results of the study showed that supply chain risk management has a direct and significant relationship with both supply chain risk information sharing and supply chain risk analysis and assessment. Supply chain risk analysis and assessment yielded a positive and significant relationship with supply chain risk-sharing mechanisms. The relationship between supply chain risk analysis and assessment and supply chain risk-sharing mechanisms was significant but weak. Supply chain risk-sharing mechanisms had a strong and positive relationship with operational performance. There was, however, no significant direct relationship between supply chain risk management and operational performance. Insights gained from this study have merit from both theoretical and practical perspectives. Theoretically, the study provides an understanding of some driving factors to supply chain risk management, supply chain risk-sharing information sharing, supply chain risk analysis and assessment, supply chain risk-sharing mechanisms and operational performance within the food retail industry in Zimbabwe. Since there is limited evidence of similar previous studies in Zimbabwean food retail firms, the results are an essential addition to the existing body of literature within the area of supply chain management and supply chain risk management in the context of a developing country. From a management perspective, the study suggests specific recommendations that should be implemented for the optimisation of all five constructs.Item Supply chain capabilities, agility and firm performance in a developing economy(Vaal University of Technology, 2019-09-09) Tlale, M. T.; Chinomona, E., Dr.; Van der Westhuizen, J. P., Dr.Nowadays, the business environment is characterised by faster technological development, customer satisfaction, shorter product life cycles, and more intense global competition. This new competitive landscape has forced firms to acquire new ways to achieve competitive advantage actively since a firm's competitive advantage is now dependent on operating efficiency and productivity across functional areas of the firm. The most successful manufacturers seem to be those that have carefully linked their internal processes to external suppliers and customers in unique supply chains. The manufacturing sector represents 15 per cent of gross domestic product (GDP) of the South African commercial industry. Competitive challenges in the modern business environment have resulted in the need for firms to collaborate their business processes strategically across other business units within the supply chain. Supply chain network theory, dynamic capabilities theory, and the resource-based view theory are discussed to better understand the importance of firms' supply chain capabilities, supply chain agility, and firm performance. The primary objective of this research study was to investigate the association between supply chain capabilities (supply chain network design, supply chain information competency, and supply chain integration) and supply chain agility on firm performance in the manufacturing sector of the Gauteng province in South Africa. It also aimed to ascertain the kind of relationships between supply chain network with supply chain agility, supply chain network with firm performance, supply chain information competency with supply chain agility, supply chain integration with supply chain agility, supply chain integration with firm performance, and finally supply chain agility with firm performance. Structured questionnaires were distributed to various manufacturing firms in the Gauteng province. The data were collected from manufacturing firm managers and owners. SPSS 25.0 was used to analyse the data, and AMOS 25.0 used to perform the confirmatory factor analysis (CFA) and path analysis. The structural equation modelling (SEM) was used to assess the proposed model fit and to test the statistically significant relationship between the various hypotheses. The research study results revealed that supply chain technologies and supply chain vi agility positively influence firm manufacturing performance. This study contributes new knowledge to the existing literature by providing a research framework that can enhance manufacturing firms' performance and also offer practical recommendations based on the research findings for manufacturing firms and future research. Furthermore, as one of the first studies to address the association between supply chain capabilities and supply chain agility on firm performance in the Gauteng province, this study generates new insights and information, as well as outlines the strategic reasons for manufacturing firms' managers and owners to improve on their organisational relationships. Hence, the study found that firms have realised significant supply chain coordination through supply chain capabilities and supply chain agility and that firms have been able to attain strategic goals, reduce risks and improve internal and external coordination of operational processes. Keywords: supply chain network design; supply chain information competency; supply chain integration; supply chain agility; firm performance.
