Extending TAM to Information Visualization: A Framework for Evaluation

February 25, 2015

Our research on Extending TAM to Information Visualization: A Framework for Evaluation is forthcoming in the Electronic Journal of Information System Evaluation.


Studies on the evaluation of information visualization techniques are flourishing, and related methodologies have been discussed in a growing number of recent studies. Yet, these evaluations concentrate mostly on usability measures and cognitive evaluations. In contrast, this contribution focuses on the various factors that drive the adoption of information visualization techniques. The Technology Acceptance Model and the Diffusion of Innovations theory are deployed to develop a framework for evaluating information visualization adoption. These seminal theories are extended and adapted to Information Visualization, resulting into a framework with three main dimensions: perceived ease of use, perceived usefulness, and perceived authority. The application of this theoretically-based evaluation framework is illustrated through positive and negative examples. As many visualization solutions have not achieved a wide use, the question of which factors foster their adoption seems to be a particularly relevant yet under-researched topic.

Knowledge Scaffolding Visualizations: a Guiding Framework

February 20, 2015

Our article “Knowledge Scaffolding Visualizations: a Guiding Framework” is forthcoming in Knowledge Management & E-Learning: An International Journal.


In this paper we provide a guiding framework for understanding and selecting visual representations in the knowledge management (KM) practice. We build on an interdisciplinary analogy between two connotations of the notion of “scaffolding”: physical scaffolding from an architectural-engineering perspective and scaffolding of the “everyday knowing in practice” from a KM perspective. We classify visual structures for knowledge communication in teams into four types of scaffolds: grounded (corresponding e.g., to perspectives diagrams or dynamic facilitation diagrams), suspended (e.g., negotiation sketches, argument maps), panel (e.g., roadmaps or timelines) and reinforcing (e.g., concept diagrams). The article concludes with a set of recommendations in the form of questions to ask whenever practitioners are choosing visualizations for specific KM needs. Our recommendations aim at providing a framework at a broad-brush level to aid choosing a suitable visualization template depending on the type of KM endeavour.

Branding Approaches of Start-Up Companies

February 18, 2015

My book on “Branding Approaches of Start-Up Companies: An Exploratory Analysis of Current Practices in Switzerland” is now available on Amazon.

Book content:

This book presents the approach to branding activities of the biggest start-up companies of Switzerland. The goal is to analyze the practices and the level of reception of branding concepts by newly created companies. For this purpose, fifteen start-up companies in Switzerland were studied and compared from the branding and corporate communication point of view. Even though a vast literature covers the topic of branding for well-established companies, still very few studies focus on the crucial starting phase of a company. The study took place in 2006 and analyzed the branding activities of fifteen among the largest Swiss start-ups. The companies are analyzed from a branding perspective through interviews, observations, website and logo analysis. Theoretical and practical implications are illustrated, with the aim to extrapolate useful information for entrepreneurs.
