communities grows, dealing with the usability attributes of these systems becomes a
challenging issue. 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.
