A framework to maximise the communicative power of knowledge visualisations

Knowledge visualisation, in the field of information systems, is both a process and a product, informed by the closely aligned fields of information visualisation and knowledg management. Knowledge visualisation has untapped potential within the purview of knowledge communication. Even so, knowledge visualisations are infrequently deployed due to a lack of evidence-based guidance. To improve this situation, we carried out a systematic literature review to derive a number of “lenses” that can be used to reveal the essential perspectives to feed into the visualisation production process.We propose a conceptual framework which incorporates these lenses to guide producers of knowledge visualisations. This framework uses the different lenses to reveal critical perspectives that need to be considered during the design process. We conclude by demonstrating how this framework could be used to produce an effective knowledge visualisation

The use of graphic rhetoric in communicating business strategy to a diverse audience : a quasi-field experiment

Communication is paramount to promoting successful implementation of business strategy. However, little research has focused on what constitutes effective communication of strategy. A quasi-field experiment was conducted to build on current research regarding whether the use of graphic rhetoric is better than text in communicating business strategy to a diverse audience. A total of 44 employees were exposed to the same strategic message through different modes of communication: one using graphic rhetoric and the other text. A pre-test was administered to determine demographics, business strategy exposure and understanding. A post-test was administered to review the levels of attention, agreement, understanding and recall. Participants were then retested seven days later to further test recall. Results suggest that graphic rhetoric can enhance the communication of business strategy across a diverse audience. Further research with a longitudinal design is necessary to understand the role of visual rhetoric in comprehension and implementation of strategy.Mini Dissertation (MBA)--University of Pretoria, 2017.za2018Gordon Institute of Business Science (GIBS)MBAUnrestricte

Usability guidelines informing knowledge visualisation in demonstrating learners' knowledge acquisition

There is growing evidence that knowledge co-creation and interactivity during learning interventions aid knowledge acquisition and knowledge transfer. However, learners have mostly been passive consumers and not co-creators of the knowledge visualisation aids created by teachers and instructional designers. As such, knowledge visualisation has been underutilised for allowing learners to construct, demonstrate and share what they have learned. The dearth of appropriate guidelines for the use of knowledge visualisation for teaching and learning is an obstacle to using knowledge visualisation in teaching and learning. This provides a rationale for this study, which aims to investigate usability-based knowledge visualisation guidelines for teaching and learning. The application context is that of Science teaching for high school learners in the Gauteng province of South Africa. Following a design-based research methodology, an artefact of usability-based knowledge visualisation guidelines was created. The artefact was evaluated by testing learners’ conformity to the visualisation guidelines. Qualitative and quantitative data was captured using questionnaires, interviews and observations. The findings indicate that the guidelines considered in this study had various degrees of impact on the visualisations produced by learners. While some made noticeable impact, for others it could be considered negligible. Within the context of high school learning, these results justify the prioritisation of usability-based knowledge visualisation guidelines. Integrating Human Computer Interaction usability principles and knowledge visualisation guidelines to create usability-based knowledge visualisation guidelines provide a novel theoretical contribution upon which scientific knowledge visualisation can be expanded.School of ComputingM.

Knowledge visualisation criteria for supporting knowledge transfer in incident management systems

During an incident, which is critical in nature, sense-making by the individuals involved are essential in ensuring an optimal response to the incident. The incident management systems employed to manage the allocation of resources to an incident allow for the visualisation of the incident and its constituents, and this visualisation supports sense-making by improving knowledge transfer. Knowledge visualisation contains pitfalls that can be avoided by implementing knowledge visualisation criteria. The purpose of this study is to identify the knowledge visualisation criteria that optimise the knowledge transfer by visual artifacts in incident management systems like emergency medical or fire-response systems. This study used the design science research (DSR) methodology and was conducted in the context of critical incident response management. A review of the existing literature was done to identify an initial set of knowledge visualisation criteria. The initial set was evaluated by content experts (using questionnaire driven interviews) and usability experts (using questionnaire driven interviews, usability testing with eye tracking and a survey) in the context of an emergency incident management system. The main contribution of this study is a validated set of knowledge visualisation criteria to guide knowledge transfer in incident management systems.School of ComputingM. Sc. Computin

Visualising Business Data: A Survey

A rapidly increasing number of businesses rely on visualisation solutions for their data management challenges. This demand stems from an industry-wide shift towards data-driven approaches to decision making and problem-solving. However, there is an overwhelming mass of heterogeneous data collected as a result. The analysis of these data become a critical and challenging part of the business process. Employing visual analysis increases data comprehension thus enabling a wider range of users to interpret the underlying behaviour, as opposed to skilled but expensive data analysts. Widening the reach to an audience with a broader range of backgrounds creates new opportunities for decision making, problem-solving, trend identification, and creative thinking. In this survey, we identify trends in business visualisation and visual analytic literature where visualisation is used to address data challenges and identify areas in which industries use visual design to develop their understanding of the business environment. Our novel classification of literature includes the topics of businesses intelligence, business ecosystem, customer-centric. This survey provides a valuable overview and insight into the business visualisation literature with a novel classification that highlights both mature and less developed research directions

A conceptual knowledge visualisation framework for transfer of knowledge : an organisational context

Revolutionary advances in science and technology enables organisations to apply and optimise a world of visual and experiential learning in order to enhance the skills and knowledge of their employees. Furthermore, the volume and complexity of knowledge and information are such that unless a reporting structure is overlaid upon it, it may remain meaningless. Knowledge visualisation uses graphical representations to convey organisational knowledge, enabling employees to share and recall relevant knowledge. However, in order to assist organisations to create and transfer knowledge more effectively through knowledge visualisation, the aim of this study is to provide a conceptual knowledge visualisation framework for the transfer of knowledge for organisations. A conceptual knowledge visualisation framework was designed through a systematic literature review process where 15 organisational knowledge visualisation elements were identified. The 15 elements were grouped and presented in a 4-layered, embedded conceptual framework that organisations may apply to their knowledge visualisation efforts. By using such a framework, organisations may optimise learning and improve knowledge and skills of its employees.http://link.springer.combookseries/558hj2021Informatic
