Item A business intelligence systems adoption framework for the small, medium, and micro-enterprises grocery retail sector : A case of Tshwane Metropolitan Municipality(2021-06-23) Muleya, Ashlyn Ennie Stubbs; Munyoka, W.; Kadyamatimba, A.Business Intelligence Systems (BIS) is regarded as a leveraging suite of tools and technologies to enhance the decision-making process of an organization by transforming data into valuable and actionable knowledge to gain a competitive advantage. While some small to medium enterprises (SMMEs) have adopted BIS technologies and are deriving benefits from them, others are confronted with a host of challenges when trying to adopt BIS. This study examined factors that are hampering the smooth adoption of BIS by SMMEs in the grocery retail sector in South Africa, focusing on the Tshwane Metropolitan Municipality, and proposed a suitable framework to guide such adoption. Three technology adoption models which underpinned this study are the technology acceptance model, task-technology fit model, and diffusion on innovation model. These models were integrated to develop a conceptual framework for the study. A survey research design was considered suitable for this study because it is the best method for generalizing the findings to the entire population. The study adopted a quantitative research approach, which is an approach for testing objective theories by examining the relationship among variables. In total, 300 close-ended questionnaires were distributed to SMMEs owners/managers around Pretoria. The data collected were analysed using the IBM SPSS version 27 software package. Multiple regression analysis was used to test the seven proposed hypotheses and to determine the statistical significance of each hypothesis. The final tested framework demonstrated that observability, trialability, perceived BIS ease of use, and perceived BIS usefulness were all positively correlated to BIS adoption. Furthermore, the framework also showed that BIS characteristics and task characteristics positively influence task technology fit. Recommendations are made for SMMEs to overcome barriers in adopting BIS, these are: there is a need for SMMEs management to invest in IT projects by allocating enough budget for technology purchase and implementation, sponsored IT support programs could enable SMMEs to increase their knowledge regarding the latest technologies they could adopt for their business, SME managers should be able to build a culture that is complimentary with technology and innovation and SMME managers should engage in strategic collaboration with other major business players to enhance learning experiences about BIS technologies.Item A context-aware collaborative decision making framework for combating terrorism in Africa(2020-06-19) Odhiambo, Nancy Achieng; Ochara, N. M.; Kadyamatimba, A.Collaborative Decision Making (CDM) is a never-ending challenge in complex-problem situations where multiple actors are involved. Complex-problem situations involve problems that are ill-defined, ill-structured and wicked such as terrorism. Problems of this nature usually warrant a collaborative effort between actors (organizations) with multiple skill-sets and expertise that at times might be at variance with each other. In order to address this gap, three sub-objectives were postulated from the main research objective, “To determine how optimal/effective CDM can be realized amongst counter-terrorism organizations through context-aware technologies.” Using the theory of synergetics and following deductive thematic analysis, the socio-technical nature of the terrorism problem was depicted by postulating a Digital Terrorism Ecology that consists of Open Digital Infrastructure (ODI), Digital Information Ecosystem (DIE), Digital Terrorism Enactment (DTE), Digital Capability and Digital Enslavement. Based on institutional theory and using PLS-SEM technique, Group/departmental relationships, Organizational co-operation, Organizational form, Technical infrastructure and interoperability, Information and knowledge sharing were identified as the factors influencing attainment of Optimal/effective CDM amongst counter-terrorism organizations. In order to explicate the role of context-aware technologies in enhancing CDM amongst counter-terrorism organizations, a context-aware CDM framework was developed following Design Science Research (DSR) methodology. In this study it was evident from the findings that attainment of OCDM in counter-terrorism contexts is challenging even though it is essential. Among the factors considered as possible influencers of attainment of OCDM, Organizational form (OF) was found to influence Organizational cooperation (OC) and Technical infrastructure and inter-operability (TI). Group/departmental relationships (GDR) were found to influence OF and OC. TI was found to influence OC and GDR and further, Information and knowledge sharing (IKS) was found to influence Optimal/effective CDM (OCDM). Of the three pillars of institutional theory, the regulative pillar offered more insights on issues related to rules, discourse and practice and hence the challenges of OCDM attainment. Practically, this study aims to re-orient the thinking of counter-terrorism organizations by presenting the socio-technical nature of the terrorism problem as well as explicating the role of digital technologies in terrorism.Item The Effect of Cyber Security on Citizens Adoption of e-Commerce Services: The Case of Vhembe District in Limpopo Province of South Africa(2019-05-18) Netshirando, Vusani; Kadyamatimba, A.; Munyoka, W.Today, information and communication technologies (ICT) have become an integral part of humans lives more especially in business, be it those in developed or developing countries. The evolution of ICT’s has also led to the introduction of e-Commerce services. Both the public and private sectors, develop these technologies with customer satisfaction in mind. Out of all the efforts by businesses and ICT experts, e-commerce systems continue to fail because of low user acceptance and user attitude, especially in developing nations. Security issues are known to be of top most concern for online shoppers. A survey was administered to 161 respondents, to find out how cyber security affects consumer’s intentions and actual use of e-commerce systems. The study encompasses both users of e-commerce systems and non-users of e-commerce systems across Vhembe district of Limpopo Province in South Africa. A quantitative research approach was used. The findings revealed that perceived security was the main concern for non-users of e-commerce intentions to use e-commerce systems because of lack of information and lack of trust on e-commerce systems. The study also revealed that users of e-commerce systems are still concerned about security, even though they intend to continue using e-commerce systems. For the success of e-commerce in rural communities, government needs to join hands with retailers and SME’s to start awareness campaigns that will clarify how e-commerce systems work and eradicate negative perception on e-commerce systems.Item Impact of digital technologies on small and medium enterprises in emerging towns: A case study of Vhembe District Municipality(2020-02) Mutobvu, Mpho Ronald; Munyoka, W.; Kadyamatimba, A.The importance of digital technologies on the growth and sustainability of small, micro and medium-sized enterprises (SMMEs) across the world need not be reemphasised. SMMEs plays a paramount role in the growth of economies, Gross Domestic Product (GDP) and the general socio-wellbeing of citizens; hence they are the driving force for employment creation. However, their efforts in adopting digital technologies to achieve their targets and growth, is not without challenges. This study establishes the impact of digital technologies on SMMEs in emerging towns in South Africa, with a focus on the Vhembe District Municipality in Limpopo Province. Guided by the Technology Organisation Environment (TOE) framework as a theoretical approach, this study proposed and tested a framework to predict factors that are impacting SMMEs. Data for testing the proposed framework was collected from 100 SMMEs owners and workers using a survey questionnaire across the Vhembe District Municipality. IBM SPSS was used to analyse the collected data using descriptive statistics and regression analysis. This study found that SMMEs with access to digital technologies have more access to information, markets, reduce operational costs while increasing the productivity and revenue. Management support regarding the use of digital technologies significantly improves the overall performance of SMMEs. This study recommend that government should provide an enabling environment through supportive policies and resources to ensure effective fusion and adoption of digital technologies by SMMEs.Item Methodology and Model to Establish Cybersecurity for National Security in Africa using South Africa as a Case Study(2016-05) Van Vuuren, Johanna Christina Jansen; Zaaiman, J. J.; Kadyamatimba, A.See the attached abstract belowItem A systems perspective of information technology (IT) governance: A case of higher education institutions in South Africa(2021-09-30) Ratshitanga, Nkhumbuleni Tendani; Ochara, N. M.; Kadyamatimba, A.Failure to implement Information Technology Governance (ITG) frameworks in universities contributes to making Information and Communication Technology (ICT) not aligned with the organizational objectives; as a result, implementation of ICT fails to create organizational value. The main objective of this study was to conceptualise a model that contributes to improving ITG in Higher Education Institutions (HEIs). Viable systems model was used as the theoretical underpinning to establish the determinants of effective ITG and to identify ITG mechanisms and their roles. The study adopted an interpretivist research paradigm. A case study research strategy was employed in HEIs. Purposive sampling was used to sample ITG role players to participate in the study; and interviews were conducted to collect qualitative data. Secondary data was collected through perusing ITG documents. The collected data was analysed using thematic content analysis and ATLAS ti 8 software that was used. The results showed the following ITG determinants: complexity in terms of internetworking and interrelatedness of ITG mechanisms, synergy of and within ITG mechanisms, ability of ITG to respond to environmental changes, local autonomy in relation to decisions taken in different ITG levels, recursive within the HEIs ITG system and direct feedback among different ITG in HEIs. The results also showed ITG mechanisms and their roles. Council, ICT steering committee, CIO, Risk Committee and Audit Committee were amongst the identified ITG mechanism. The study concluded that Council is responsible for strategic envisioning; executive management is responsible for planning; Chief Information Officer (CIO) controls and directs ITG activities, ICT Steering Committee coordinates the development and implementation, Risk Committee and Audit Committee monitor the process, the ICT department; under the supervision of the CIO; and Sections within the ICT department are hands on regarding the implementation. The VIVHO ITG model is the outcome of the synthesis of the identified ITG determinants and ITG mechanisms.Item Towards an e-learning adoption framework for rural-based higher education institutions in South Africa(2019-05-18) Patel, Naziyabanu Mohmedsalim; Kadyamatimba, A.; Madzvamuse, S.The aim of this research study is to propose an e-learning framework to deliver a guideline for the adoption of e-learning considering all major determinants such as technical, operational, organisational, cultural and socio-economical domains, in the setting of rural-based higher educational institutions. E-learning is a process which has arisen from ICT advancement, and it is coordinated together with the education programs at many universities. In South African tertiary institutions, the adoption rate for e-learning is higher in urban-based higher education institutions and colleges and lower in rural-based higher education institutions. Even though with the supposed capacity that e-learning provides, the bigger part of the e-learning approach in rural-based higher education institutions does not achieve their potential. This study focuses on identifying factors which impact the adoption of e-learning at rural-based, higher education institutions and its challenges. A case study approach is undertaken, using mixed methods for collection of data from the respondents based on e-learning adoption at student, educator and institutional level. The study identified the factors which influence the adoption of e-learning in rural-based HEIs. Eventually, the researcher proposed an e-learning framework which contributes to the e-learning adoption in rural-based HEIs, by establishing a guide for these institutions for enhanced planning, development and implementation tool for e-learning adoption using the Unified Theory of Acceptance and Use of Technology Model. The study identified that the e-learning usage and perception was lower in rural-based HEIs as compared to urban-based HEIs, and performance expectancy, effort expectancy, social influence and facilitating conditions are all major factors which influence the adoption of e-learning.Item Unbounded rule-based expert system for selecting software development methodologies(2019-05-16) Macheque, Vhutshilo; Kadyamatimba, A.; Tutani, D.; Ochara, N. M.The extent of success of a given project can be increased by using an appropriate Project Management Methodology (PMM) that takes into account the specific characteristics of the project (such as complexity, size, budget, nature of risk, etc.). PMMs have evolved over the years to become more diverse, complex, with evolving and dynamic ICT platforms. Such PMMs have traditionally been used as frameworks to guide the project management process for decision makers (such as Project Managers, Project Owners and Project Teams). The choice of selecting an appropriate project methodology is daunting; apart from other considerations related to project characteristics such as budget, scope, schedule, performance and resource constraints. One of the vital stages of a successful software development project is selecting a good software development methodology that best suits that project. The aim of this research is to investigate the critical factors to be considered by project managers in the selection of the software development methodology for the project. These critical factors are then used as a foundation for an architecture for an “unbounded rule-based expert system. A survey was conducted amongst project managers to determine the critical factors necessary for the selection of a software development methodology. From the findings of the study, it was established the critical factors revolved around three constructs of Project Excellence Enablers, Excellent Project Management Practices, and Business Value Proposition factors. The findings from this study therefore provided a rationale and a basis for the evolution of an “Unbounded Rule-Based Expert Systems Architecture” as a basis for the selection of the right software development methodology
