  • Description: Abstract: Current situation in business, economies and the world indicate that artificial intelligence (AI), the Internet of Things (IoT) and robotics are some of the technologies that is and will continue to have a tremendous impact on businesses, economies and everyday human life. These technologies amongst others are reshaping the global landscape and business ecosystems and the manner in which business is conducted in the fourth industrial revolution (4IR). Generic commercialisation lifecycles and business models require adaptation in the 4IR, which will aid successful business for a knowledge management (KM) consulting firm. The study focussed on conceptualising and developing a commercialisation lifecycle (CLC) for a KM consulting firm in the 4IR. The research objective was to conceptualise a business model canvas (BMC) and develop an IKM framework that can be used specifically by a KM consulting firm, including entrepreneurs, small businesses and professional business consulting firms in the 4IR. Literature shows that commercialisation lifecycles and business models need to change continuously, especially on the front of the 4IR. To remain competitive and sustain a healthy business, KM consulting firms will need to upskill and improve current business operations. Upskilling, changing and preparing for the 4IR, give competitive advantage over competitors. New technologies need to be embraced and harnessed to exploit the innovative capabilities and value add new technologies offer. With an improved, adapted and updated CLC and BMC in place, a KM consulting firm will be able to provide innovative services to clients, ensuring profitability. The research methodology for the study was qualitative in nature, with an inductive and exploratory approach. Grounded in the interpretivist paradigm, the inductive approach allowed the study to explore a specific phenomenon and identify themes in order to explain patterns. A conceptual framework was developed, using existing literature, to conceptualise a CLC for a KM consulting firm in the 4IR. Data was collected through content analysis and in-depth faceto- face interviews, through multi-method qualitative research. Purposive sampling was selected to determine the 4 participants for the interviews, through critical case sampling, allowing 3 participants to be interviewed and the fourth participant to be used for testing the findings of the interviews. Interviews and testing of the interviews were transcribed, coded, and categorised through the Data Analysis Spiral. Research findings, through triangulation found that the conceptualisation and development of a CLC is crucial; that the conceptualisation of a BMC is crucial; and that new services and the development of an IKM framework is crucial; which will allow a KM consulting firm, including entrepreneurs, small businesses and professional business consulting firms to be successful in the 4IR. Results showed that the CLC, the BMC, new services and the IKM framework, need... , M.Phil. (Information Management)

  • Description: Abstract: Electrical contractors are facing an inevitable transition in the near future. There has been a slow increase in the construction industry. As a result, the electrical contractors have a constricted market in which to compete. At the same time, new technology, such as Internet of Things (IoT) and Power over Ethernet (PoE), challenge the way electrical contractors execute their business operations. IoT refers to how multiple equipment is interconnected via computer network systems. PoE enables electrical power to be transmitted over a computer network cable, effectively replacing a general purpose electrical cable in certain applications. This new technology creates a new dawn of Smart Buildings and, thus, reduces the scope of the uninitiated electrical contractor even further. To remain competitive in the changing environment, increased training and skills development are demanded from electrical contractors. The aim of the research is to determine the impact of futuristic technology on the operations of the electrical contractors by asking whether electrical contractors are sufficiently skilled to install and maintain smart building products. The research was conducted through litterature review and a questionaaire which was distributed to 20 targeted indivials. Out of the 20 targeted individuals, 17 were able to complete the questionnaire. A resultant return rate of 85% was achieved. The main finding was that additional skills were required for traditional electrical contractors to enter smart building market. These additional skills were found to emanate from ICT industry. , M.Phil. (Engineering Management)

  • Description: M.Ing. (Engineering Management) , Abstract: The research aims to identify the factors that are important for the adoption and intention to use the Internet of Things (IoT) in future by municipality employees for management of water services at a local municipality. Currently local municipalities collect, store and manage some data on water services provisioning, which might as well not be accurate, and unfortunately they struggle to make timely and accurate decisions on management of water services. IoT is seen as one of the solutions that will alleviate this problem however, in order for it to be implemented in future, it must be successfully accepted and used by the employees of the local municipality. The research uses the Technology Acceptance Model (TAM) to identify those TAM factors and associated moderating factors that are important to the employees in order to successfully accept the Internet of Things for a timely and accurate decision-making process for the management of water services in future. The TAM factors and associated moderating factors were analysed using quantitative statistical methods in SPSS. The statistical analysis confirmed which TAM factors that are needed to accept IoT in future for timeous and accurate decision-making in the management of water services and that the moderating factors are not necessarily needed.

  • Description: Abstract : Blockchain technology is a relatively new technology which provides many opportunities for knowledge-mapping. Blockchain technology is best described as a decentralised ledger system that stores information about transactions and uses digital currencies such as Bitcoin. The best possible utilisation of a new technology usually depends on how quickly people can develop and apply new knowledge of the technology. Knowledge is a key component to leverage the most useful features of any new technology. Moreover, it is crucial to know how to avoid the pitfalls of a new technology in order to develop solutions. This study’s unit of analysis is knowledge of blockchain technology, that is, the knowledge possessed by people operating in the banking industry. The banking industry is sternly regulated in all jurisdictions and employee know-how is a valuable resource. The recent wide dissemination of blockchain technology, the popularity of cryptocurrencies, and the Initial Coin Offering have contributed to the fact that financial institutions’ management underline the vast potential of blockchain technology in the financial industry. For example, large banks are conducting tests of decentralised asset technology and implementing decentralised ledger systems in business processes. Banks are investing in projects and start-ups that are developing blockchain-based solutions. Therefore, bank employees with know-how and prior experience with blockchain are essential to create blockchain solutions. The objective of this study is to map the existing know-how and identify knowledge gaps of blockchain technology know-how and its possible application in a South African Banking Institution (SABI). This is done through an analysis of knowledge of how the utilisation of blockchain technology changes the existing operations models of financial institutions. The research methodology consists of an inductive knowledge-mapping strategy and mixed-method approach. The quantitative data collection method involved gathering data via an online questionnaire sent to a purposive sample, namely, SABI’s clients, investors, experts, and individuals with the common denominator: Blockchain technology knowledge interest who had attended the Blockchain Africa Conference. The qualitative data collection method was an interview with individuals who had a specific technical knowledge of blockchain technology, with the common denominator: SABI blockchain knowledge group. iv The data analysis was sequential; the quantitative data analysis was followed by qualitative data analysis. The findings identify categories of knowledge that are needed to inform and build new blockchain technology-based operations models. Knowledge gaps were identified in the SABI. Based on the findings, the study conceptualises a knowledge map and develops a theory, namely: If the blockchain knowledge maps of financial institutions integrate knowledge across their Core Banking Application pillars, then the financial services industry will create an Internet of Value-Exchange advantage for everyone on the network. Further study is required in order to test this theory. A key recommendation is to perform knowledge-mapping of the Core Banking Application pillars as the next step of SABI’s knowledge maturity of blockchain technology. In conclusion, knowledge maturity of blockchain technology is essential to create an Internet of Value-Exchange advantage for everyone within the network. The mapping of knowledge provides a measurement of knowledge maturity. Blockchain technology provides many opportunities for knowledge-mapping. , M.Phil. (Information Management)

  • Description: Abstract: This paper presents the collected experimental data for water quality monitoring which was conducted in ten experiments by using five different common sources of water contaminants namely soil, salt, washing powder, chlorine and vinegar and their combination. The data were collected indoors at room temperature during the day for several days using sensors that measure pH, turbidity, flow rate, and conductivity in water. The water consumption risk (CR) was calculated as deviation based on the water quality parameters standards proposed by the World Health Organisation (WHO) and the South African Department of Water Affairs (DWA), with respect to the sensor measurement readings obtained. While the error measurements were calculated based on the expected parameter measurement per conducted experiment and repeated for 26 measurements. Pure tap water was the benchmark of water safe for human consumption. The first five experiments were performed by introducing each contaminant into the water and thereafter, two contaminants in the sixth experiment and their additions until all different contaminants were experimented at once in the last experiment.
