This issue has introduced the necessity of developing a new conceptualisation focusing on development and enhancement of system usability attributes of a TC business system. This thesis proposes a models and applications framework for value-added investigation of the usability attributes associated with the TC business system. The proposed framework comprises five usability attributes (such as user awareness, user interpretations, service competence, application excellence, and user experience) of a TC business system. However, four of these attribute namely the user awareness, user interpretations, service competence, and application excellence contributes towards the fifth attribute of user experience of a TC business system. Therefore the proposed framework comprises five layers namely, business, knowledge, service, application and fuzzy cognitive interpretation. Each layer is modelled, applied, and investigated with regard to its strengths and limitations. Based on the proposed framework along with the usability attributes, comprehensive sets of hypotheses are formulated and several testing methodologies are dealt with. Thus, a multi-perspective evaluation of the proposed models and applications framework is undertaken to capture the usability dynamics of the system. To begin with an exploratory analytical study is undertaken to enhance the apparent usability awareness among system users, through development of a User Awareness Model at the business layer. Next, a descriptive analytical study is undertaken to provide consistent apparent usability interpretations of the system, through development of a User Interpretations Model at the knowledge layer. This is followed by an analytical hypothesis testing, conducted to provide service competence of the system, through development of a Service Competence Model at the service layer. Next, the hypothesis related to the application excellence is then developed and tested by an analytical approach, through development of a set of Network-level Application Excellence Models at the application layer. As a final step, a User Experience Model is developed to estimate the Final Quality of Experience (FQoE) of the system users at the fuzzy cognitive interpretation layer. Therefore, the usability value propositions described in the proposed framework will enhance the state-of-the art of an emerging TC business system across several e-business communities, resulting in a competitive advantage.
