- Description: The Nigerian Construction Industry faces a problem of poor materials management that leads to, among other things, materials waste, poor quality of work, poor materials flow, project delay and cost overrun. Overcoming these challenges, requires the rethinking the current modus operandi of the Nigerian construction industry. One such method that has been espoused as having potential to improve materials management, and associated challenges is ‘lean production’. This research aimed at deciphering the lean approach to production management with a view of extracting its utility in enhancing materials management in the construction industry. The qualitative method of research inquiry that is rooted in the phenomenological paradigm was employed. The research activities included a comprehensive review of the related literature and study of selected cases. Abuja, the Federal capital territory of Nigeria was the selected geographical scope of the research. Ten case studies were purposefully selected for the study. The research instrument was a tick box used for direct observation. The study revealed that poor materials management has a negative effect on the materials management plan. Moreover, mixing of waste at the site, negates the effort for identification of materials waste streams, and makes it difficult to account for materials waste, as well as implementing a materials waste management policy on sites. The research also found that poor materials management has a significant effect (high, moderate or low) on materials waste, quality of work, materials flow, productivity, project delay, project profitability and accounting for materials. The research has developed a conceptual model for a lean production approach to materials management based on the results and informed by the theoretical framework. The study has achieved its aim of establishing an understanding of the lean production approach to materials management in the Nigerian construction industry. The study recommends that construction professionals should be well informed on the effects of poor materials management.

- Description: The purpose of this study was to develop and empirically test the Supply Chain Integration Framework (SCI framework) in order to develop a framework to address the inefficiencies experienced in the public hospital pharmacies’ Supply Chain (SC) in Kenya. Supply Chain Management (SCM) can be regarded as a vibrant business entity that is changing and evolving continually because of constant changes in technology, competition and customer demands. The study investigated and analysed how the independent variables, namely SCI initiatives, performance improvement drivers, organisation environmental forces, workforce and management support, financial factors, flow and integration, regulatory framework and information sharing and technology influenced the SCI. The SCI was categorised into three components namely: customer order fulfilment, supplier collaboration and dedicated SC as the dependent variable. The literature reviewed established that globalisation and intensive worldwide competition, alongside technological developments, creates a completely new operating environment for organisations. The researcher reviewed various models and theories related to SCI which include systems theory, value chain models and value ecology models among others. An SCI framework was then developed to capture the interacting variables within the SCI network that could be adopted for the public hospital pharmacies in Kenya. The study was conducted using a survey questionnaire (Annexure B) that comprised both open and closed ended questions that were distributed to managers in public hospitals and pharmacies in Kenya. The population for the survey was 154 public hospital pharmacies in Kenya, with the final sample comprised of 280 respondents. The study was conducted using a survey questionnaire (Annexure B) that comprised both open and closed ended questions that were distributed to 325 respondents in 154 public hospitals and pharmacies in Kenya. The population for the survey was 154 public hospital pharmacies in Kenya, with the final sample comprised of 280 respondents. Exploratory factor analysis was used to ascertain the validity of the measuring instrument and the Cronbach alpha coefficients were used to measure the reliability of the measuring instruments. Key preliminary tests performed were the Kaiser-Meyer-Olkin test (KMO test) of sample adequacy, the Bartlett’s test of sphericity and the Kolmogorov-Smirnov test (Z-Statistic test) for normality and multi-collinearity diagnostic. Analysis of Variance (ANOVA) and multiple linear regressions were the main statistical procedures used to test the regression model fit and the significance of the relationships hypothesised among various variables in the study. Statistical softwares, namely Statistica 10 (2010) and Statistical Package for Social Sciences (SPSS) Version 18, were used to analyse quantitative data. The study identified five statistically significant relationships between customer order fulfilment and workforce and management support, financial factors, flow and integration, information sharing and technology, supplier collaborations and dedicated SCI. In addition, a total of six statistically significant relationships exist between the supplier collaborations and SCI initiatives i.e. performance improvement drivers, workforce and management support, financial factors, flow and integration, information sharing and technology adoption as well as dedicated SCI. Furthermore, four statistically significant relationships were found between dedicated SCI and SCI initiatives, workforce and management support, financial factors, flow and integration, information sharing and technology adoption.

- Description: The study assessed the effects of materials management practices (materials planning, procurement, availability, handling, and delivery) on the performance of rail rolling stock and locomotive manufacturing firms in Gauteng Province. The study also investigated the causes of delays in supply of materials in the rail rolling stock and locomotive manufacturing industry in Gauteng. The research design employed was both descriptive and explanatory, using a quantitative research approach in which online surveys were conducted on a sample of 200 respondents from the rolling stock manufacturing firms in Gauteng. Descriptive statistics performed through SPSS 27 and SEM performed through AMOS 26 were used for data analysis. The findings of the study revealed that materials management practises were implemented in the rail rolling stock and locomotive manufacturing industry. According to the results, materials availability and materials handling have positive and statistically significant effects on the performance of rail manufacturing firms in Gauteng Province. However, materials planning, procurement and delivery practices have no significant effect on the performance of rail manufacturing firms in Gauteng Province. Therefore, the results reveal that firm performance is driven by materials availability and materials handling. In addition, late delivery of materials to the production line was found to be the main cause of project delays. The study thus offered a contrasting perspective to the general findings that show materials management practices to be a significant contributor to manufacturing firm performance. However, the study confirms the importance of materials handling and availability as a predictor of performance in manufacturing firms. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2023

- Description: The central aim of this study was to assess the engagement of supply chain stakeholders, namely OEMs and an automotive supplier, in relation to customer-specific requirements. This objective was accomplished by identifying the communication methods employed by both parties for addressing customer-specific needs. Additionally, the study aimed to pinpoint the factors that promoted engagement between OEMs and automotive suppliers concerning these requirements. Conversely, it aimed to uncover the factors that hindered such engagement. Lastly, the research aimed to evaluate whether this engagement effectively alleviated the pressures faced by the automotive supplier regarding customer-specific requirements. The broader goal of the research was to comprehend how supply chain stakeholder engagement operated between OEMs and an automotive supplier with respect to customer-specific requirements. This was pursued through secondary objectives, which entailed examining how communication transpired between OEMs and an automotive supplier, the degree of participatory nature in this communication, the barriers and catalysts influencing customer-specific requirements, and whether this engagement mitigated the pressures borne by the automotive supplier. These objectives were instrumental in revealing opportunities for enhancing OEM communication, thereby positively contributing to their relationships with supply chain partners and mitigating the added burdens they faced. The research followed a qualitative case study design, utilizing semi-structured interviews to delve into the experiences of participants carefully selected from an automotive supplier. These participants were chosen based on their interactions with OEM customers, thereby providing pertinent insights into these interactions. Thematic analysis was employed for data analysis, uncovering codes, categories, and overarching themes from participants’ responses. The findings of the research highlighted certain consistent themes, shedding light on which communication methods were employed more frequently, as well as the rationale behind their usage. Notably, online platforms emerged as a popular channel, and daily communication was preferred. The research also revealed a recurring theme wherein OEMs assumed a controlling role, rather than fostering a mutually advantageous partnership in addressing issues. Additionally, communication barriers were observed in the use of online portals for communication by the automotive supplier. In these themes, variations were discerned in communication channels. These differences were rooted in participants’ responsibilities, decision-making authority, and designated roles. Consequently, the perception of communication channels varied among participants. However, similarities were also noted in the participants’ feedback regarding communication channels. The research highlighted the necessity for improved two-way communication and emphasized the need for a collaborative approach between OEMs and the automotive supplier, rather than a unilateral one. The research underscored an evident power imbalance between OEMs and the automotive supplier. In essence, the crux of a successful and mutually beneficial engagement between OEMs and the automotive supplier lies in transparent communication, adaptability, and a shared willingness to find solutions that cater to both sides. By focusing on these core principles, it is plausible to establish a scenario that benefits both parties and nurtures a robust and enduring partnership. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2024
