- Description: D.Phil. (Engineering Management) , Abstract: Small, Medium and Micro Enterprises (SMMEs), are playing an important role in the economy and this has led the South African government to set-up various support mechanisms. The support strategies set-up by the government include access to finance, training and helping SMMEs with compliance with both labour and tax regulations to enable them to operate formally. However most SMMEs operate in a very competitive environment. Motor body repair (MBR) SMMEs are faced with the ever changing repair technology and equipment required by newer vehicles introduced to the market by the original equipment manufacturers (OEMs). It is important therefore for SMMEs to understand and measure their business performance in order to improve their business practices. Literature suggests that performance measurement tools can help businesses to identify problem areas and improve processes by aligning objectives with strategies. Research reviewed shows that most theories on performance measurement and management that have been developed suit large corporations and very few meet the needs of SMMEs. The purpose of this study was to investigate through business model, entrepreneurship, managerial and technical capability constructs the business performance of SMMEs operating in the South African MBR sector. Theories that were used were: systems theory, management theory, organisational theory, entrepreneurship theory, behavioural theory of the firm and economic theory. These theories were integrated with business model constructs, managerial and entrepreneurial factors. The aim was to determine how entrepreneurs, the insurance industry, bankers and motorists interact and contribute to the performance of MBR SMMEs and in so doing develop a performance driven business model and technical capability framework for the South African MBR sector. Five objectives were identified in this research study. The first objective was to investigate economic forces that impact on MBR SMMEs’ business model environment in the sector in the last five years, (2012-2016). The second objective was to investigate the structure, business models and processes found in the South African MBR sector. The third objective was to investigate the technical capability of SMMEs operating in the MBR sector. The fourth objective was to explore the associations of business model, technical capability, managerial and entrepreneurship constructs of a selected group of SMMEs with their business performance over a five-year period, (from 2012 – 2016). The fifth objective was to develop a performance driven business model and technical capability framework that can be used by SMMEs in the MBR sector. These objectives were achieved through a research design which included a literature review, an initial survey and the triangulation of survey results, semi-structured interviews, case studies and simulation modelling. Both qualitative and quantitative data were collected. Quantitative data was analysed through IBM SPSS Version 23 and a multiple regression model was used to analyse the survey data. Statistical methods used included descriptive statistics, frequencies, custom tables, principal component analysis (PCA), Kaiser-Meyer Olkin (KMO), Bartlett’s Test of Spherecity, Reliability-Cronbach alpha, exploratory factor analysis (EFA) and correlations. Two case studies were carried out and semi-structured questions were used to gather information on the structure, processes and factors negatively impacting on SMMEs in the MBR sector. Processes found in the MBR sector were simulated and areas of improvement were identified. The research developed both the technical capability framework and a performance driven business model for the South African MBR sector. The technical capability framework shows functioning abilities; specific knowledge, and technical skills, required by a company. The business model framework shows the relationships among the different business model components and how the company can use them to create and deliver value to its different stakeholders. Research results show that a performance driven business model and technical capability framework can help SMMEs in the MBR sector to formulate the correct strategies that will help them to manage their businesses in an environment that is full of uncertainty. The business model and technical capability framework must align with SMMEs daily processes as required by key activities, key resources, budgeting (cost and revenue), key partners and targeted customers. The business model and technical capability framework can help these SMMEs to identify customer needs and manage and measure customer satisfaction. The literature confirms that SMMEs suffer from various problems in their daily business that include poor management, poor strategic orientation, lack of marketing, poor infrastructure, poor financing and poor perception from the public. The structure of the MBR industry makes it difficult for new players to enter the market due to regulations laid down by South African...

Five medium sized engineering companies that are into manufacturing of steel products were selected for detailed case studies. The focus of the study looked into two main issues, firstly how these companies formulated their manufacturing strategies, secondly how training, communication and leadership impacted on the implementation of their strategies. Overall business performance for these companies was assessed for a period of three years. A relationship was established between manufacturing strategy and business performance. The ability of the employees to deliver a quality product, through a sound quality assurance process was found to correlate with business performance. Employee oriented leadership was found to have supported a smooth implementation of the manufacturing strategy, while inadequate training methods and task oriented leadership were found to stifle the successful implementation of a manufacturing strategy.

- Description: This research investigates perceived barriers faced by Small, Medium and Micro Enterprises operating in the South African motor body repair sector. Despite various support strategies spearheaded by both Government and private sector for the development of these small businesses, not much has been achieved in this particular sector due to lack of research. An exploratory survey was carried out to ascertain barriers to enterprise development needs of auto body repairers. Funding opportunities are still scarce, causing a negative impact on equipment acquisitions, infrastructure development and access to market. There is need for proper multiskilling training on motor body repairs. Support measures for enterprise development for auto body repairers include the need to set up; dedicated lines of credit, acquisition of appropriate repair equipment from Original Equipment Suppliers, certified training from Original Equipment Manufacturers’, specific sector focus from various small business funded programmes, procurement of proper infrastructure and employment of better marketing strategies to remove poor business perception from the public. Unless measures are taken to address these problems the disadvantaged communities will forever lumber in poverty.

- Description: A case study research was carried out on four manufacturing small and medium enterprises that are involved with new product development. Literature suggests that survival, growth and competitiveness of small and medium manufacturing enterprises are based on their ability to develop and introduce new products into the market. New product development has become a central mechanism through which a company’s strategy can be put into practice. Literature suggest that few articles have been written on new product development problems faced by small and medium manufacturing companies. The paper confirmed constraints faced by small and medium enterprises in developing new products such as lack of resources, poor coordination among various departments, lack of project management structures, weak strategic thinking, poor absorptive capacity and non-use of new product development frameworks. Small and medium companies must enable flexibility of staff movement among various departments to enable concurrent development of new products. Problems associated with lack of resources can be averted through formation of industry portals that can aggregate flexibility and agility. The time taken to develop new products can be reduced through sharing of information with their alliances and external networks including universities.

- Description: Abstract: This paper evaluates the impact of Total Productive Maintenance (TPM) in a railway and mining component manufacturing company. Literature suggest that TPM is an approach innovative to maintenance and its major goals are no defects, no accidents and no breakdowns. Many authors have argued that TPM improves quality, equipment productivity, prevents unexpected breakdowns and reduces defects. Reliable manufacturing equipment is considered as a major contributor to the profitability and performance of manufacturing systems in today’s extremely evolving environment. Most organizations function effectively today because the equipment is reliable and available thereby maximising production throughput and profit. A case study was conducted and it involved a mixed method approach where both quantitative and qualitative data was gathered and analysed. The company implemented TPM through the following initiatives; autonomous maintenance, employee improvement, planned maintenance, quality maintenance, education and training and safety and health. TPM was implemented for eighteen months. This study made use of the following maintenance improvement tools, TPM, Failure Mode Effects and Critically Analysis (FMECA) and cause and effect diagram. Maintenance performance factor such as Overall Equipment Effectiveness (OEE) was analysed before and after TPM implementation. The results of this study showed that TPM implementation contributes to equipment reliability. There was an improvement in overall organizational performance. Through FMECA, maintenance tasks were prioritized and risk priority numbers (RPN) were calculated for particular equipment. Key performance indicators such as productivity and OEE were on an upward trend while there was a reduction in defect rates. Communication among workers, workers and management, and among different departments was improved. Worker motivation was improved through autonomous maintenance. However maintenance performance in some departments was found to be too low due to unavailability of data and worker inconsistency. This paper contributes to the theory and practice of TPM implementation.

- Description: Abstract: This paper aims to optimize a manufacturing process through creation of a simulation model that will be used to identify bottlenecks, restructure the layout and improve productivity. The paper also highlights the significance of process optimization in a manufacturing set up. Process optimizations strive to find the best solution for a process within the available constraints. Simulation is a collection of methodologies used to mimic the characteristics and behaviour of real system using computer software. Literature review was carried out to understand system dynamics and simulation. A case study was conducted at a manufacturing company. An Arena simulation model representing the process under study was developed and analysed. Various models were run and the results compared. The best model was developed that improved productivity through restructuring of the layout and minimization of the cycle times on the identified bottleneck stations. The simulation results showed that there was a vast difference on the amount of material input and the ATMs and Safes produced. The limitation of this study was that it only focused on the production of two products in the case studied company.

- Description: Abstract: Internationally the demand for industrial engineers is growing, due to the economic downturn as well as constraints on natural resources. Yet, at the University of Johannesburg, the majority of students who seek admittance to the engineering faculty do not choose industrial engineering as their first choice. A quantitative study was done by surveying industrial engineering students in the first and second year, to determine the number of engineering students at UJ whose first choice was industrial engineering. In addition the satisfaction with the course of those students who did not choose it originally was determined. We investigated the impact of open days and engineering weeks, as arranged by the University, on pupils’ choice of industrial engineering? The study found that a large portion of students did not choose industrial engineering as their first choice and it seems to be due to a total lack of knowledge with regard to industrial engineering. The perceptions of school pupils of engineering need to be changed and issues with the current standard of high school mathematics need to be explored further. The question to ask is: How can we improve the marketing of industrial engineering as a career.

- Description: Effective use of performance management (measurement) system enables companies to improve on their competitiveness in the marketplace. Through a case study research, the paper reviews the performance management system of a local manufacturing company. Most researchers have focussed on wide range of performance management surveys and few paid attention to individual companies, which is the focus of this paper. The balanced score card framework was used to evaluate both internal business processes and external outcomes. Four perspectives of the scorecard; financial, customer, process and learning were looked into. The paper established that top management is clear and committed to the company’s strategy and goals. The company is struggling to increase its market share due to lower levels of productivity. High levels of rework were noticed on the shop-floor and are impacting negatively on their cash-flow. These problems have led to poor customer retention due to unmet delivery dates. The paper proposes that the company must initiate staff development programmes to enable a culture of continuous improvement.
