Performance measurement has been in existence and the subject of research for at least two decades. However, it would appear that the Small and Medium Enterprise (SME) sector lags behind other industries in terms of harnessing performance measurement with strategies that call for design skills, such as design thinking. Scholars in developed economies have given only limited attention to the contributing role of design thinking in performance measurement and improvement. Most research in these disciplines focuses primarily on using design thinking during the design phase rather than integrating it throughout the performance measurement processes. However, integrated performance measurement is now receiving increasing attention within the SME context internationally due to the potential benefit of design thinking for strategy. However, while research on performance measurement within South African SMEs is growing, it nevertheless lacks practical perspectives. This is cause for concern, as an absence of knowledge about and understanding of processes followed during performance measurement could deprive the SME sector of the benefit of integrating design thinking for organisation sustainability. Empirical data were collected from fourteen SMEs using semi-structured interviews, case and documentary analysis and focus group discussions conducted with owner-managers, and analysed. The findings indicate that both contextual and conceptual factors contribute to enterprise performance, and that understanding the processes, performance and execution and tracing their effect on performance measurement are vital. Four process phases of an integrated performance measurement framework emerged from the analysis, namely pre-strategy planning, strategy planning, strategy implementation and post-strategy implementation. These trigger actions which guide and support interaction between leadership and stakeholders and encourage iteration between thinking, trying and the actual discovery of key drivers to monitor, improve and change performance. The findings suggest that the integration of performance measurement is possible with some balanced scorecard and design thinking-related principles engendered in whichever process is deemed natural to configure, improve and evolve by this iteration between thinking and acting. The implications, therefore, include the need for commitment by SMEs to facilitating performance measurement initiatives within their current practices. In addition, the owners or managers and policymakers need to consider ways to assist and play a role in promoting and enhancing the ability of SMEs in performance measurement integration for sustainability. / Isilinganiso sokusebenza besikhona futhi besiyisihloko yocwaningo okungenani amashumi amabili eminyaka.

Nogtans lyk dit asof die sektor vir Klein en Middelslagondernemings (KMO's) ’n agterstand teenoor ander nywerhede het wat betref die benutting van prestasiemeting met strategieë wat gebruik maak van ontwerpvaardighede soos ontwerpdenke. Navorsers in ontwikkelde ekonomieë het slegs beperkte aandag geskenk aan die bydraende rol van ontwerpdenke in prestasiemeting en -verbetering. Die meeste navorsing in hierdie dissiplines fokus tydens die ontwerpfase hoofsaaklik op die gebruik van ontwerpdenke, in plaas daarvan om dit deurgaans met die prestasie-metingsprosesse te integreer. Geïntegreerde prestasiemeting geniet egter nou toenemende internasionale aandag binne die KMO-konteks, weens die moontlike strategiese voordele van ontwerpdenke. Terwyl navorsing oor prestasiemeting egter in Suid-Afrikaanse KMO's groei, ontbreek daar nogtans praktiese perspektiewe. Dit is kommerwekkend, aangesien 'n gebrek aan kennis oor en begrip van prosesse wat tydens prestasiemeting gevolg word die KMO-sektor kan ontneem van die voordele van geïntegreerde denke vir organisatoriese volhoubaarheid. Empiriese data is van veertien KMO's ingesamel deur die gebruik van semi-gestruktureerde onderhoude, gevalle- en dokumentêre-ontleding, asook fokusgroepbesprekings wat met eienaarbestuurders gevoer en daarna ontleed is. Die bevindinge dui aan dat beide kontekstuele en konseptuele faktore tot prestasies van ’n onderneming bydra en dat begrip vir die prosesse en werksverrigting, asook die uitvoering en opsporing van die uitwerking daarvan op prestasiemeting, noodsaaklik is. Vier prosedurefases van 'n geïntegreerde prestasiemetingsraamwerk het uit hierdie ontleding het na vore gekom, naamlik pre-strategiebeplanning, strategiebeplanning, strategie-implementering en post-strategie implementering. Hierdie fases veroorsaak aksies wat interaksie tussen leierskap en belanghebbendes lei en ondersteun, en moedig iterasie tussen denke, strewe en die werklike ontdekking van sleuteldrywers aan om prestasie te monitor, verbeter en verander. Die bevindings dui daarop dat die integrasie van prestasiemeting moontlik is met ’n tipe gebalanseerde telkaart en sommige ontwerpverwante denkbeginsels wat aangekweek word in watter proses ook al beskou word as die natuurlike om te konfigureer, verbeter en ontwikkel deur hierdie iterasie tussen denke en aksie. Die implikasies sluit dus die behoefte in van ’n onderneming deur KMO's om prestasiemetingsinisiatiewe in hul huidige praktyke te fasiliteer. Daarbenewens moet die eienaars of bestuurders en beleidmakers oorweging skenk aan maniere om te help en ’n rol te speel in die bevordering en verbetering van KMO’s se vermoëns om prestasiemeting vir volhoubaarheid te integreer / College of Accounting Sciences / D.

M. Tech. (Department of Industrial Engineering and Operations Management, Faculty of Engineering), Vaal University of Technology. / The current business environments in many companies are characterized by markets facing tough competitions, from which customer requirements and expectations are becoming increasingly high in terms of quality, cost and delivery dates, etc. These emerging expectations are even getting stronger due to rapid development of new information and communication technologies that provide direct connections between companies and their clients. As a result, companies should have powerful control mechanisms at their disposal. To achieve this, companies rely on a number of functions including production scheduling. This function has always been present within companies, but today, it is facing increasing complexities because of the large number of jobs that must be executed simultaneously. Amongst many factors, it is time driven. This study demonstrates that several disciplines can be married into one model (i.e. a unified model) to solve scheduling problems after disruptions, and clears the way for future multi-disciplinary research efforts. Scheduling problem is modeled as follows: Ito’s stochastic differential rule is used to analyse the time evolution of random or stochastic processes. Multifactor productivity is used to unify various disruption factors. Theory of line balancing is also employed to determine the required number of resources to minimize bottleneck. Reliability: disruptions are considered to be equivalent to system failure. The failure rate of the system is translated to the reliability of the system mathematically. The probabilities of failure are used as indicators of disruptions, and the theory of reliability is then applied. Bernoulli’s principle is also employed to relate pressure to production flow and aid in managing bottleneck situations. Results indicate that the amount of resources needed after disruption depends on the nature of disruption, and that the scheduler should plan to increase number of facilities following a trend that is only predicted by the nature of disruptions. It is also shown that disruption of one type may not greatly affect productivity of a certain company layout, whilst similar disruptions can have devastating effect on another type. It is further concluded that impacts of disruption are dependent on the type of company layouts.

Thesis (M.Com. (Economics)) -- University of Limpopo, 2022 / The purpose of this study was to investigate growth through innovation and productivity in the South African economy. The study employed the Autoregressive Distributed Lag (ARDL) approach to analyse the annual time series data from the period 1994 to 2018. The data of the study is quantitative and was collected from the South African Reserve Bank and the World Bank. Due to a decline in investment in innovation in South Africa as compared to Brazil, Russia, India and China, the study recommends increased investment in innovation, which may yield positive results on economic growth given the Fourth Industrial Revolution (4IR) presence. The results of the study indicate that there is a long-run relationship between the variables furthermore, in the short-run research and development (R&D), several patents and manufacturing: Labour productivity has a positive and is statistically significant on GDP. However, labour productivity in the non-agricultural sector is positive but statistically insignificant on GDP. Moreover, the findings, in the long run, reveal that R&D, number of patents, and manufacturing: labour productivity is positive and statistically significant on the economic growth in South Africa while labour productivity in the non-agricultural sector has a negative impact on economic growth. This study recommends that policymakers should aim at increasing government-funded R&D, education and human capital to induce productivity and eventually drive up economic growth in South Africa.

The aim of this study is to determine the role that innovation plays in economic development and how an economic environment can be created that is conducive to innovation. The urgent need for development in large parts of the world indicates the importance of the increase in innovative activities because innovation is indicated as the “engine of growth and development”. It was found that innovation takes place within an innovation system and should be studied from a system perspective. The system perspective implies that there are different participants and that these participants function individually but that they also interact (wittingly or unwittingly) with one another. The innovation system is defined as a system that includes the participants or actors and their activities and interactions, as well as the socio-economic environment within which these actors or participants function, which determine the innovative performance of the system. A system approach is therefore necessary to study the influence of innovation on development. The role that innovation plays in economic development has been established by means of the historical patterns of economic development and major innovations as well as an analysis of literature of empirical studies. The historical pattern indicates the importance of innovation for economic development, but literature revealed the complexity of the relationship due to the non-linear relationship among different actors or participants in an innovation system. The main determinants of innovation was identified and a conceptual, descriptive model for an innovation system was developed, indicating the different participants, their roles, the interaction among them, and the economic environment within which the participants function. The model was applied to the Mpumalanga province in South Africa as case study. Strengths and weaknesses were identified in the Mpumalanga innovation system and recommendations were made for the improvement of the Mpumalanga innovation system which in turn should lead to an improvement in the economic development of the province. / Economics / D.Comm.

The present study is an attempt to analyze the impact of changing policy regime during the liberalization era on the behaviour of 81 sample firms in Indian electronics industry in terms of factor productivities. We categorise a period of 12 years (1993-2004) as the two phases of liberalisation: - Period/ Phase 1: 1993-1998 and Period/ Phase 2: 1999-2004. The 81 sample firms are segregated into four primary sub-sectors of electronics industry based on their use pattern: communication equipments, computer hardware, consumer electronics and other electronics. The objective is to trace the growth of output in the four sub-sectors in Indian electronics industry over two phases of liberalisation and to determine the relative contributions of Input Growth (IG) and Total Factor Productivity Growth (TFPG) to Output Growth (OG). Further, the study focuses on determining the relative contributions of Technological Progress (TP) and Technical Efficiency Change (TEC) to TFPG and establishes the influence of firm specific managerial decision making and management efficiency variables on TEC and TP. The methodology follows a three-step approach in order to achieve the above objectives. The first step is to determine a potential stochastic production function using stochastic frontier production function model and measure firm-wise technical inefficiency levels. The second step is to measure the growth of TFP over two phases and to derive the components TEC and TP. The third step measures the influence of management decision variables on TEC and TP using a frontier approach model on a panel data. The contribution of labour to output was found to be higher than the contribution of capital in all four sub-sectors. However, capital contribution improved in phase 2 relative to phase 1 for computer hardware and other electronics sub-sectors. Computer hardware was the only sub-sector that experienced an improvement in returns to scale from constant returns to scale in phase 1 to increasing returns to scale in phase 2 of liberalisation. The Technological Progress (TP) and Technical Efficiency Change (TEC) that contributed to TFPG exhibited a contrasting relationship for all the four sub-sectors in the electronics industry: TEC declined when there was high TP while it improved when there was a decline in TP. This could be because Indian electronics firms generally focus on either technology imports/ develop indigenous technology to achieve TP or to assimilate the imported/ indigenous technology for better use. The lag in assimilation of imported/ developed technology could be a reason for the negative relation between TEC and TP. The communication equipment sub-sector had a balanced growth in terms of TEC and TP among the four sub-sectors. The computer hardware and the other electronics sub-sectors were worse performers in terms of TEC in period 2 relative to period 1 and so had been the electronics industry as a whole. The computer hardware sub-sector had the highest average OG in period 2 relative to period 1 among all the sub-sectors due to relatively high contribution of IG. Other electronics sub-sector had the highest average TP that compensated for the negative average TEC. On an average, percentage contribution of TP to TFPG was high for the electronics industry and its sub-sectors in period 2 relative to period 1. This is an indication that the sub-sectors of Indian electronics industry have strived and achieved steady technological progress in the period of economic liberalisation to cope with the intensifying competition internally as well as externally. The sample firms in the electronics industry were in favour of towards external acquisition of sophisticated technology, which explains the relatively high contribution of TP to the TFPG of the industry. However, this was not followed up with adequate in-house R&D in order to develop indigenous technology or to absorb imported technology as a result of which TEC for the sub-sectors and the whole industry suffered. Growth in Operating Margin (OMG) and Growth in Returns on Capital Employed (ROCEG) generate additional revenue that could be ploughed back into the firm for improvement of its existing indigenous technology or absorption of imported technology thereby leading to improvement in TE and TP. The positive influence of OMG as well as ROCEG on TEC and TP for all the sub-sectors is an indication of efficient management in these sub-sectors in utilizing assets and profits to generate earnings. However, the trend of operating margin and returns on capital employed had been declining for all the sub-sectors. Inventory management proved to be costly for TP as financial resources diverted to maintain inventory had an undesirable effect on their indigenious technology. Most of the sample firms in the electronics industry were found to have incurred R&D expenditure to derive tax incentives. As a result the resources got diverted away from other creative operational or skill improvement efforts to unproductive and wasteful R&D activities. Thus, R&D did not have the desirable influence on the components of TFPG. The present study showed that unplanned and ad hoc technology imports or even raw material imports was not conducive to the growth of both the components of TFPG. Older firms need to develop their technology or adequately import better and more sophisticated technology. This would enable older (more experienced) electronic firms to overcome the negative influence of age, reflected in our analysis. This is, however, applicable to only those segments of the electronics industry where firms preferred to serve lower end of the market as well as lower end of the technological spectrum (eg. Computer hardware and other electronics sub-sectors). Electronics industry like any other capital goods industry offers scope for vertical integration. Management of the firms in electronics industry should emphasize on vertical integration, expansion of scale of operations and should initiate R&D investments to build up R&D base, among others to improve TEC and TP. This would also help to check the decline in operating margin and returns from invested capital among the firms. Thus, improved managerial effectiveness and decision making do help in the form of generating thereby surpluses facilitating to achieve higher TP and even TEC. Regional and State governments should provide adequate policy support and appropriate industrial infrastructure to electronic firms which would in turn improve their managerial effectiveness and TFPG.

This research explores the role, which the construct, service quality plays in an internal marketing setting. This is achieved by evaluating the perceptions and expectations of the production department with regards to the service quality provided by the maintenance department of a South African motor vehicle manufacturer. This was done using the INTSERVQUAL instrument, which was found to be a reliable instrument for measuring internal service quality within this context. A positivist approach has been adopted in conducting this research. There are two main hypotheses for this study: the first hypothesis is concerned with the relationship between the overall internal service quality and the five dimensions of service quality namely: tangibles, empathy, reliability, responsiveness and reliability. The second hypothesis focuses on the relationship between the front line staff segments of the production department and the five dimensions of internal service quality. The results of this research suggest that the perceptions and expectations of internal service customer segments plays a major role in achieving internal service quality. In addition, the importance of the INTSERVQUAL instrument in measuring internal service quality within the motor vehicle manufacturing environment is confirmed.

Abstracts in English and Xhosa / Given the need for prompt responses to today’s dynamic market, maintenance and maintenance management functions are becoming increasingly fundamental for industrial companies. Reduction of waste and bottlenecks, particularly the reduction of overproduction and work in process, accentuates the impact of malfunctions or failures of equipment on production. As such, it has become ever more urgent for proactive world-class maintenance to turn to computer-based support for efficacious management. To successfully manage activities such as the scheduling of activities, the planning of preventive maintenance actions, the analysis of data (to reduce the occurrence of malfunction and failures), and augment the absolute performance of the maintenance function, industrial companies implement information systems enabled by computerised maintenance management systems (CMMS) to deliver timely and accurate information. However, while various CMMS are available on the market, not all meet the exactitudes of each industrial company. The overall objective of this thesis is threefold: to explore major barriers and obstacles that have a negative impact on implementing CMMS; to identify the most common critical success factors (CSFs) that have a positive impact on implementing CMMS; and to develop an optimised CMMS model suitable to the context of Ethiopian manufacturing industries. To achieve this, an exploratory descriptive research design was employed, utilising both quantitative and qualitative data-gathering techniques, including structured interviews and questionnaires. Both qualitative and quantitative findings Suggest that the most important CSFs for CMMS implementation were work planning and scheduling and work identification and responsibilities, while the Ethiopian manufacturing firms lagged behind in the case of information technology and appraisal. Overall, key isues in maintenance management range from several maintenance techniques, information systems, scheduling, and optimisation models. This thesis is projected to be a useful source of information for both maintenance managers and stakeholders in CMMS decision making. It also creates opportunities for future research in this area of study. / Ngenxa yesidingo seempendulo ezikhawulezileyo kwimarike yanamhlanje eguqukayo, ukulondoloza kunye nololondolozo lwemisebenzi yolowulo ziya zisanda ngokubaluleka kwiinkampani zoshishino.
