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.
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.
Drivers of procurement performance in the public health industry in the Gauteng province
(Vaal University of Technology, 2022-01) Masemola, Shilela Catherine; Van der Westhuizen, J. P., Dr.; Omoruyi, O., Dr.
The purpose of this study was to investigate the relationship between supplier selection practices, supplier risk management, supplier commitment and procurement performance in the public health industry in Gauteng province. Many studies have been conducted on the specific subject of procurement performance within the public health care sector. However, there is very little evidence that any such studies have been carried out that have precisely been narrowed down to the specific subject of the dimensional relationships and linkages between Supplier selection, supplier risk management, supplier commitment and procurement performance in the public health industry in South Africa. This study, therefore, was conducted to fill this gap. To measure the study constructs, the survey material was designed in the form of a structured questionnaire. Participants were asked to complete four test instruments namely: supplier selection questionnaire, supplier risk management questionnaire, supplier commitment and procurement performance questionnaire. A total number of 200 questionnaires was distributed to the identified sample of public health industries of which 187 responded and finally, 150 questionnaires were usable and used for data analysis. The collected quantitative data were analysed using the SMART-partial least squares (SMART-PLS 3) structural equation modelling procedure. The actual data analysis techniques applied included descriptive statistics and inferential statistics using structural equation modelling. Also, the latter used a SMART-PLS 3 to test the psychometric properties of measurement scales and the testing of the six hypotheses using the path analyses technique. The results of the study showed positive and significant relationships amongst all variables except for one. Specifically, supplier selection and supplier risk management exerted a moderate and significant influence on supplier commitment. Moreover, supplier commitment had a strong positive and significant relationship with procurement performance while supplier risk management had a weak and insignificant relationship with the same factor. More results provided from the analysis confirmed the existence of a very strong and significant relationship between supplier selection and procurement performance. Besides, the study takes note of its contributions to highlighting its merits. From a theoretical perspective, it provides an in-depth examination of some driving factors to supplier selection, supplier risk management, supplier commitment and procurement performance within Public health entities. Given that a study of this nature has not been performed before amongst South African public health care sectors, the results are an essential addition to the existing body of literature within the area of procurement performance within public health industries in developing countries such as South Africa. The study concludes by suggesting recommendations for limiting the impact of the identified challenges on procurement performance.
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.
E-Procurement, supplier integration and supply chain performance in small and medium enterprises in Gauteng Province
(Vaal University of Technology, 2018-10) Madzimure, Jeremiah; Mafini, Prof. C.; Dhurup, Prof. M.
The purpose of this study was to investigate the relationship between e-procurement, supplier integration and supply chain performance in Small and Medium Enterprises (SMEs) in the Gauteng Province of South Africa. Most studies on e-procurement, supplier integration and supply chain performance have focused on large companies. Current knowledge involving SMEs and e-procurement is still limited. This study, therefore, was conducted to fill this gap. With rapid changes in technology and globalisation of markets, firms, especially SMEs, need support to adapt to technology and make use of e-procurement functions to compete with larger firms. The paradigm used in this study was post-positivism. A quantitative research approach was adopted in this study. The target population for this study consists of all owners and managers who are currently employed in SMEs in the Gauteng Province, South Africa. To measure the study constructs, the survey material was designed in the form of a structured questionnaire. Participants were asked to complete three test instruments, namely, an e-procurement questionnaire, supplier integration questionnaire and supply chain performance questionnaire as well as their profile and SME profile. A total number of 350 questionnaires was distributed to the identified sample of SME owners and managers of which 294 responded and finally 283 questionnaires were usable and used for data analysis. The confirmatory factor analysis (CFA) was performed to establish scale accuracy. All measures conformed to acceptable model fit and composite reliability (CR) and revealed that the scales used in this study are reliable. The reliability results confirmed that all constructs reached the generally agreed upon minimum scale range for Cronbach’s alpha of 0.70. Finally, the structural model was tested; four out of seven hypotheses were supported. Validity in this study was achieved through face, content, convergent and discriminant validities. The principal finding of this study reveals that e-design has a positive and significant linear relationship with supplier integration. In addition, the results showed that e-sourcing has a positive and insignificant linear relationship with supplier integration. The insignificant relationship could be indicative of the fact that enterprises are not fully utilising the e-procurement systems in selecting their suppliers to effectively improve their collaboration with supply chain member firms. The findings further reveal that e-negotiation has a positive and significant linear relationship with supplier integration. The study’s empirical findings also indicate that e-evaluation has a negative and insignificant relationship with supplier integration. Further, e-informing was also found to have a negative relationship with supplier integration. The study additionally revealed that supplier integration has a positive and significant linear relationship with tangible supply chain performance. Lastly, the SEM findings show that supplier integration has a positive and significant relationship with the intangible supply chain performance. After reviewing the results, the conclusion was drawn that theoretically, this research has contributed to literature by providing additional information on supply chain management, e-procurement, supplier integration and supply chain performance. The results presented provide useful information about the relationship between e-procurement, supplier integration and supply chain performance in SMEs, with implications for supplier firms and other relevant stakeholders. These results contribute to the expanding body of knowledge on supply chain aspects. The current study added practical value by developing an integrative model which might be used by SME practitioners in South Africa. The study recommends that the collaborating firm owners and managers consider increasing the levels of supplier collaboration by having regular meetings, training workshops or courses and conferences to improve their supply chain performance. Furthermore, it is recommended that SME owners and managers must effectively implement e-design systems to increase the chance of integrating with their suppliers, thereby increasing the chance of improving performance as well as cutting supply chain costs. Areas for further research and limitations for this study have also been highlighted.
An empirical exploration of supply chain constraints facing the construction industry in South Africa
(Vaal University of Technology, 2016) Pillay, Poobalan; Mafini, Chengedzai, Dr.; Pooe, David, Prof.
The South African Construction Industry is one of the largest contributors to the gross domestic product of the country as well as to employment. It has, however, been experiencing significant challenges due to multifaceted factors. The main objective of this research was to identify the supply chain management constraints within the South African Construction Industry and how these can be overcome. This study is by nature descriptive and exploratory and contains qualitative elements. The problems were identified through a literature review, focused group discussions and interviews with major construction companies in South Africa. The findings also indicate that the main supply chain management constraints are to a greater extent internal and typical of supply chain methodologies and approaches. These constraints are among others the lack of coordination, collaboration and commitment between suppliers and clients within the supply chain, poor leadership in key areas of systems, design problems (many changes and inconsistent information), deficient internal and external communication and information transfer, inadequate management within the supply chain, mainly poor planning and control just to mention a few. A model based on supply chain system management as well as the Theory Of Constraints (TOC) has been developed that can be a useful tool to address the constraints in the construction sector. Originating from the study are applicable recommendations for the South African construction industry supply chains, covering key themes that have been articulated in the study, particularly benchmarking to the theory of constrains. Such recommendations include further research core components of supply chain such as, collaborations, logistics and how each of system components can be linked to performance of the supply chain management system.
An evaluation of the supplier relationship management and procurement practices at a parastatal: the case of Eskom Holdings Limited
(Vaal University of Technology, 2014) Jonathan, Ellsworth C.; Mahlasela, E. R., Dr.; Pooe, David, Prof.
The primary objective of this study was to investigate the supplier relationship management practices at Eskom. Currently, the challenges faced by the parastatal include diminished reserve margin, increased unplanned generation plant outages as well as coal supply and quality constraints coupled with ever-rising primary energy costs. It is, therefore, evident that as a national asset, Eskom cannot overcome the current challenges successfully without strong partnerships with key suppliers. A framework for supplier management containing four different elements was researched. The first element, which forms the basis for all supplier management operations, is the development of supplier management relationships. The framework also includes supplier collaborations and the various aspects of discovery, supplier pre-selection, and supplier selection, which relate to finding, qualifying, and choosing the best suppliers. Lastly, and also very important was the supplier development and localisation as well as the legislature thereof. A quantitative cross-company survey was conducted using a sample of 260 suppliers, who have been on the database for more than twelve (12) months and who responded to the business requests to update the data on the system. The findings of the study are largely supported by the literature. Finally, the study makes recommendations and highlights further research, managerial, and policy implications.
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.
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.
A framework for the effective creation of business incubators in South Africa
(Vaal University of Technology, 2019) Lose, Thobekani; Mafini, C., Prof.; Dhurup, M., Prof.
The majority of business incubators in South Africa are supported by the Small Enterprise Development Agency (SEDA). However, a notable proportion of business incubators face a number of challenges to growth and development. Despite a number of studies conducted on business incubators generally, little information exists on the framework for the creation of business incubators. The concept of business incubation has gained prominence in academia in recent years as a vehicle for small business development. In view of the growing importance of business incubators, the objective of this study is to develop a framework for the creation of business incubators in South Africa. Business incubator managers, coaches, project specialists, and enterprise development practitioners were selected, being considered the ideal target population for this study. The study adopted a sequential mixed-methods methodology that commenced with a qualitative study and was followed by a quantitative study. For the qualitative study, data were collected from a purposively selected business incubator sample comprising nine participants. The principle of technical saturation was applied to ascertain the adequacy of the sample size. The trustworthiness and credibility of the qualitative study were achieved through pre-testing of the interview guide, bracketing, prolonged engagement with participants, peer debriefing, and researcher reflexivity. The analysis of the qualitative data was conducted using content and thematic analyses. The qualitative element of the study identified incubator prerequisites, situational analyses, operational processes/incubation strategies, and operational outputs as the main determinants of the framework for business incubators. In line with the methodology of the study, the determinants of the framework for business incubators that emerged from the qualitative study were further examined through a quantitative study. The data for the quantitative study were generated from a conveniently selected incubator practitioner sample of 121 respondents, using a structured self-administered questionnaire. Furthermore, the historical evidence method guided the determination of the sample size for the quantitative study. Prior to questionnaire administration of this study a pilot study was conducted to improve the accuracy of the survey instrument. The quantitative section utilised statistical data analysis procedures, descriptive statistics, reliability and validity analysis, correlation analysis and confirmatory factor analysis. The Statistical Package for Social Sciences (SPSS) software was utilised to analyse the quantitative data. The results of the quantitative data analysis revealed that the framework for incubation presents incubator prerequisites (incubation entry of incubatees) as the predictor construct. This construct has eight sub-components, which are situational analysis (incubatees’ characteristics), key requirements, operational process, factor components, intellective capabilities, administrative capabilities, market force engineering, and strategic resourcing (impact) with KPIs. The mediating construct is business incubator performance (incubation process—industry coaches, governance structure, and entrepreneurial focus), which in turn leads to monitoring and evaluation (incubation output—graduation phase, impact, and follow-ups). The relationships between these constructs were tested. In order to verify the reliability of the measurement items of the current study, Cronbach’s alpha coefficient, the item-to-total values and composite reliability were computed. The validity of the survey instrument was enhanced through content, convergent, discriminant and predictive validities. In addition, the reliability and validity measures employed in the present study showed that the survey instrument utilised in the quantitative study was both reliable and valid. The study is significant in terms of its theoretical and business incubation policy implications. Theoretically, the study provides a comparative impression of the South African business incubation perspective and current trends in the ecosystem. Thus, future researchers, particularly in developing countries, may use the results of this study as a reference benchmark in terms of literature and research methodology. The various organs of the state, government agencies, as well as non-governmental organisations that are responsible for entrepreneurship development and the creation of additional business incubators, may use the study as a reference point in the generation of different initiatives aimed at improving the small business environment in South Africa.
Green supply chain practices and supply chain performance in the beverage industry of South Africa
(Vaal University of Technology, 2020-04) Mahlatsi, Michael Kgaisi; Omoruyi, Osayuwamen, Dr.; Chinomona, Elizabeth, Dr.
In South Africa, the beverage industry is perceived to be a major contributor to the economy. Internal and external stakeholders in this industry are engaged in environmental collaboration with each other to achieve better environmental and supply chain performance. The aim of this study was to investigate the influence of green supply chain management practices on environmental performance and supply chain performance in the beverage industry of South Africa. It considers four of these practices, namely, internal environment management, investment recovery, eco-design and green purchasing. A quantitative approach was adopted, with the use of a survey questionnaire to collect information from 373 supply chain management professionals from beverage companies in South Africa. The study used a probability simple random sampling method. The data gathered was analysed using the Statistical Package for the Social Sciences (SPSS) version 25.0 and Analysis of a Moment Structures (AMOS) version 25.0. A Confirmatory Factor Analysis (CFA) was used to validate the measurement scales while Structural Equation Modelling (SEM) was applied to test the relations between constructs. The results revealed that internal environment management, investment recovery, eco-design and green purchasing positively and significantly influence environmental performance. Moreover, the results also revealed that environmental performance exerted a strong, significant and positive influence on supply chain performance. Recommendations and implications for further research were made based on these results. The study presents supply chain management professionals, internal and external stakeholders within the beverage industry with useful insights on key factors that ought to be addressed in order to improve their organisational strategies. Therefore, the study is essential to internal and external stakeholders in the beverage industry who wish to improve environmental and supply chain performance.
The implementation of green supply chain management: minimising environmental risk in the South African manganese and phosphate mining industry
(2013-12) Bvuma, Khomotso; Pooe, R. I. D.; Mathu, K. M.
This study explored the implementation of green supply chain with regard to minimizing environmental risk in the South African manganese and phosphate mining industries. A qualitative research paradigm methodology was used. Theoretical assumptions were utilized. References by other researchers in the green supply chain and mining supply chain were also used to broaden the knowledge horizons for the study. A total number of twelve supply chain and environmental professionals from the key role players in the South African manganese and phosphate mining industries were interviewed and provided valuable input to the study. The study determined lack of information sharing between the role players in the supply chain that lead to the discovery of themes and sub–themes. The study identified seven main themes and eleven sub-themes as challenges in the implementation of green supply chain. Recommendations to address the challenges areoutlined and include the introduction of cleaner production practices by using cleaner technologies, inclusion of environmental aspects in the sourcing strategy, among others. The achievement of all these will ensure sustainable development. Originating from the study are research recommendations for the South African manganese and phosphate mining industries. The recommendations include further research to establish a green supply chain model as well as perception and expectations of policy makers in the industries.
The influence of knowledge-sharing, business strategy alignment and long-term relationships on supply chain performance in the small and medium enterprise sector
(2015-04) Mofokeng, Teboho Mantebele; Chinomona, R.; Makhitha, K.
The purpose of this study was to investigate the influence of knowledge-sharing, business strategy alignment and long-term relationship orientation on supply chain performance in the Small and Medium Enterprise (SME) sector. Particularly, the study sought to examine the hypothesis in the context of SME buyers and their suppliers. SMEs are particularly relevant to both developed and developing countries. In South Africa, SMEs are perceived to be an engine for growth for both the economy and the community. As such, the study sought to investigate underlying variables that influence the supply chain performance of SMEs for the purpose of identifying ways in which the Sector can improve performance. A conceptual model was developed, drawing from the theory of relational cohesion. Small and Medium Enterprises in the province of Gauteng, South Africa formed the population of the study. Essentially, the predicting roles of knowledge-sharing and business strategy alignment on the supply chain performance of SMEs were evaluated. Furthermore the mediating role of long-term relationship orientation was examined. A survey was conducted in the cities of Johannesburg, Vereeniging and Vanderbijlpark and research data was collected from 341 SMEs. Statistical Package for the Social Sciences (SPSS) 22 was employed to analyse data as well as Analysis of Moment Structures (AMOS) 22 where Structural Equation Modelling (SEM) was undertaken. The results revealed that the research constructs knowledge-sharing, business strategy alignment and long-term relationship orientation influence supply chain performance in a positive way. The findings realized will contribute to the existing body of buyer-supplier relationships literature and increase our knowledge in the field. Pragmatic implications are provided based on the findings as well as recommendations and avenues for future research.
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.
The influence of supplier information sharing and information quality on strategic partnerships and internal lean practices among small to medium enterprises in South Africa
(2015-05) Sikhwari, Tina Mesmer; Chinomona, R.; Mathu, K.
The focus of this study was to examine the relationship between information sharing, information quality, strategic partnership and internal lean practices among Small and Medium-sized Enterprises in South Africa. It is essential to understand practitioners’ and entrepreneurs’ current knowledge towards the topic at hand in order to determine what interventions would be most beneficial in helping to curb the problem of the lack of knowledge in this area and to understand the underlying causes behind the problem, while creating awareness and giving new insight to those who are already aware of this topic. Data was collected from a sample of 350 Small to Medium Enterprises and the measurement items in the measuring instrument were measured using a 5-point likert scale. Thereafter the collected data was coded and analysed by means of structural equation modelling using the AMOS 21 software package. The results indicate that supplier information sharing and information quality have a strong influence on strategic partnership and in turn strategic partnership has a strong influence on internal lean practices among Small to Medium Enterprises. This indicates that the level and quality of information shared between Small to Medium Enterprises and their suppliers has a positive effect on the strength of their partnerships as well as on the internal practices of each Small to Medium Enterprise. Based on these results, conclusions were drawn and recommendations were put forward on how internal lean practices in Small to Medium Enterprises can be improved by means of information sharing, information quality and strategic partnerships.
The influence of supply chain networks, flexibility and integration on the performance of small and medium enterprise in the Southern Gauteng region
(2015) Omoruyi, Osayuwamen; Dhurup, M.; Pooe, R. D.
The South Africa economy has embraced the importance of small and medium enterprises (SMEs) as agents of economic growth and sustainability. However, for SMEs to be more efficient and effective towards the growth of the economy, it is important for SMEs to implement and take cognisance of the global competitive strategy among the so-called “best in class” organisations in order to also sustain and grow their business. The supply chain network with its flexibility has become the most commonly used business strategy worldwide for the improvement of performance in organisations, more especially among larger organisations. In today’s competitive environment, successful organisations are those that have been able to link their business functions within the organisation itself as well as across other businesses outside the organisation. Competitive challenges in the modern business environment have resulted in the need for organisation to integrate business processes strategically across other business units within the supply chain network. Network perspective theory, social network theory, network management theory and relational view theory are discussed to better understand the importance of SMEs supply chain network, flexibility and integration. The purpose of this study was to examine the influence of supply chain network, flexibility and integration on the SMEs business performance in the Southern Gauteng region. The research survey was conducted in the Meyerton, Vereeniging and Vanderbijlpark and 401 SMEs participated in the study. SPSS 22.0 was used to analyse the data and AMOS 22.0 was used to perform the confirmatory factor analysis. The structural equation modelling (SEM) was used to assess the proposed model fit and to test the statistically significant relationship of the hypothesis. The research study results revealed that supply chain network, flexibility and integration positively influence SMEs business performance. This study contributes new knowledge to the existing literature by providing a research framework that can enhance SMEs performance and also provide practical recommendations based on the research findings for SMEs and for future research. Furthermore, as one of the first studies addressing the influence of supply chain network, flexibility and integration on the performance of SMEs in the southern Gauteng region it has generated new insights and information as well as outlined the strategic reasons for SME owners and managers to improve on their business relationships.
The influence of supply chain practice on supply chain performance in South Africa
(2015-03) Hove, Progress; Pooe, David; Mathu, Ken
The effective implementation of intra-firm and inter-firm supply chain practices and processes such as supply chain e-collaboration and sharing of important information among supply chain partners, is commonly associated with the creation of supply chain competitiveness and enhanced performance. However, little attention has, thus far, been given to the empirical investigation of the influence of the successful implementation of intra-firm supply chain practice on supply chain e-collaboration, strategic information sharing, supply chain competence and supply chain performance in South Africa. The principal objective of this study was to fill this void by investigating the influence of intra-firm supply chain practice on supply chain e-collaboration among supply chain partners in South Africa. Secondly, the study sought to determine the influence of supply chain e-collaboration on strategic information and supply chain competence among supply chain partners in South Africa. It also aimed to examine the influence of strategic information sharing on supply chain competence and ultimately on the supply chain performance of supply chain partners in South Africa. Lastly, the study sought to ascertain the influence of supply chain competence on supply chain performance of supply chain partners in South Africa. A positivist approach that allowed a quantitative research method in data collection was used in this study. Data from a sample of 280 collaborating firm owners/managers from all the industries of South Africa’s nine provinces was used for the final data analysis of this research. A principal component analysis was performed for factor reduction and dimensional groupings using SPSS 21 software. Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) were performed for model fit assessments and hypotheses tests respectively, using the Analysis of Moments of Structure (AMOS 21) software. Multiple Regression analysis was performed using SPSS 21 software, and was used for comparison and support of the weak and unsupported SEM hypotheses tests. The principal finding of this study reveals that intra-firm supply chain practice has a strong positive and significant influence on supply chain e-collaboration among supply chain partners in South Africa. In addition, the results showed that supply chain e-collaboration can strongly and significantly enhance the sharing of strategic information among supply chain partners in South Africa. The findings further revealed that supply chain e-collaboration has an ability to create a supply chain competence among supply chain partners in South Africa. The study’s empirical findings also indicate that strategic information sharing has a weak positive and significant indirect influence on supply chain competence and supply chain performance. Lastly, the SEM findings showed that supply chain competence has a weak negative and insignificant influence on supply chain performance. However, the multiple regression analysis showed a weak negative and significant influence of supply chain competence on the supply chain performance of supply chain partners in South Africa. The conclusions and implications of the empirical research findings are provided and recommendations are suggested. The study suggests a new supply chain management conceptual model for research. It also proposes a new supply chain management implementation framework to help guide firms to formulate strategies for improving supply chain performance. The study recommended that the collaborating firm owners/managers consider: training and education for all employees on the importance of supply chain practices and processes such as supply chain e-collaboration and strategic information sharing. Furthermore, it is recommended that collaborating firm owner/managers should consider adopting advanced technologies and information sharing structures to improve their supply chain performance. The collaborating firm owner/managers were also encouraged to align their incentives with the supply chain roles and activities assigned to the supply chain partners. Policy makers were encouraged to make e-business financing arrangements for supply chain collaborating firms; promote synergies between collaborating small and mediums firms and large technology vendors; and ensure affordability of supply chain e-collaboration technologies. The study attempted to address the intra-firm supply chain practice deficiencies on the side of both the supply chain e-collaborating firms and the government.
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.
Lean practices and supply chain competitiveness in the steel industry in Gauteng, South Africa
(Vaal University of Technology, 2022-07) Khoza, Sizwe; Okoumba, L., Dr.; Mafini, C., Prof.
This study examines the influence of lean supply chain management (LSCM) on supply chain competitiveness in the steel industry in Gauteng, South Africa. The industry suffered a huge blow when imported steel took over the market and collapsed big players within the industry in South Africa.A range of problems hit the market hard, leaving companies applying for section 189 of the labour law to reduce overheads and restructure their organisations. It is evident that organisations need to change their way of thinking,heighten their supply chain strategies and adopt international standards like lean supply chain management practices to become competitive in a broader spectrum. Using a data set of 265 supply chain professionals drawn from the steel manufacturing industry in Gauteng, results showed the importance of proper implementation of LSCM woulddirectly influence SCC, leading to improved organisational performance. The collected quantitative data were analysed using the Statistical Packages for Social Sciences (SPSS version 27.0) statistical software.Techniques such as correlations and regressions were used to test the hypotheses.The results of the study showed that four lean practices, namely Just in Time, Total Quality Management, Strategic Partnership and Waste Elimination all predictthe establishment of a lean culture. However, Human Resource Management was statistically insignificant. The results further showed that Lean culture predicts the competitiveness of the steel supply chain. Thererefore, an emphasis on lean supply chain management in the steel industry is anessential contributor to its success.
Linking inventory management practices to inventory and warehouse performance in the retail industry in Gauteng and KwaZulu-Natal Provinces
(Vaal University of Technology, 2022-11) Jama, Moeketsi; Mafini, C., Prof.; Loury Okoumba, W. V., Dr.
The application of inventory management practices to improve inventory and warehouse performance is a critical concept in supply chain management. These activities are fundamental in contributing to the value creation of firms' supply networks. The present study investigated the link between inventory management practices, inventory performance and warehouse performance in the retail industry in Gauteng and KwaZulu Natal provinces. The study used a quantitative approach based on a combination of correlation and survey design methods to examine the identified relationships. A total of 203 supply chain professionals selected from retail outlets in the Gauteng and KwaZulu Natal provinces participated in the survey. The collected data were analysed using the combination of Statistical Package for Social Sciences and the SMART PLS software. Major data analysis techniques employed in the study included descriptive statistics, Exploratory Factor Analysis and Structural Equation Modelling. The results show that the three inventory management practices: inventory investment, inventory control and ABC analysis, positively influence inventory performance. Two practices: inventory turnover optimisation and shrinkage prevention were statistically insignificant. Additionally, Inventory performance positively influenced wareho use performance. Theoretically, the study provides a comprehensive analysis and contributes to the literature on inventory and warehouse management in the retail industry in South Africa. Practically, the study facilitates more informed inventory and warehouse management problem diagnostics and decision-making by managers and supply chain professionals in the retail industry.
