Electronic banking services in South Africa : service quality scale development and validation

PhD (Marketing Management)--North-West University, Vaal Triangle Campus, 2015.The rapid advancement in technology-based systems, especially those related to the Internet and World Wide Web, has led to fundamental changes in how banks interact with customers. These developments have propelled banks to be innovative and use alternative delivery channels such as electronic banking with a view to attract more customers, create value for customers, enhance customer satisfaction and ultimately obtain customer loyalty. Within the South African context, a gap in research was identified that dealt with the conceptualisation and measurement of electronic banking service quality. Furthermore, no single empirical or conceptual study could be found that put up the four constructs identified in this study that tested the causal relationships of these constructs. Against this backdrop, the study‘s principal objective was to develop and validate a measuring scale of electronic banking service quality for the South African banking sector. The study also sought to determine the causal relationships amongst the four constructs of the study, namely electronic banking service quality, customer value, customer satisfaction and customer loyalty. To address these research objectives, the study applied a two-phase design in conducting the research in an effort of enhancing and maximising the outcome of this research endeavour. Phase I of this study comprised a literature review and focus group interviews (qualitative research). An extensive literature review was conducted as an inductive method to build the theoretical foundation of the study, generate the initial pool of items, and define and conceptualise the constructs. Using a deductive method, the focus group interviews were used to generate original items for the development of the scale. Phase II of the study comprised scale refinement and validation of the scale through various interactive statistical applications such as exploratory factor analysis (EFA) and structural equation modelling (SEM) (quantitative method). Using an exploratory factor analysis, eight determinant dimensions were extracted that constitute electronic banking service quality (EBSQ). These dimensions in accordance of their importance are reliability, system availability, privacy and security, website aesthetics, ease of use, functionality, efficiency, and contact and responsiveness. The Pearson‘s correlation coefficient between each of the eight dimensions and EBSQ was above 0.6 at p
