Purpose: This article aims to explore the so-called illusion of explanatory depth (IOED) of managers regarding their understanding of digital technologies and examines the effect of knowledge visualization one's current understanding and decision making. Its purpose is to show that managers think they know more than they do and that this affects decision making but can be reduced through knowledge visualization. Design/methodology/approach: In two experiments with experienced managers, the authors investigate the size and impact of the IOED bias in decision making and examine if sketched self-explanations are as effective as written self-explanations to reduce the bias. Findings: The findings show that experienced managers suffer from a significant illusion concerning their explanatory understanding of digital technologies and that sketching one's current level of explanatory understanding of these technologies supports the accurate calibration of one's knowledge. The findings indicate that sketching knowledge is a helpful modality for the detection and subsequent recalibration of biased knowledge in domain-dependent decision making. Originality/value: This article is the first to explore the effect of sketched knowledge externalization on the calibration of explanatory knowledge of managers. It extends the literature on both, the IOED and on knowledge visualization as an instrument of knowledge calibration. [ABSTRACT FROM AUTHOR]

Purpose – This paper aims to study hybrid knowledge visualization in police crime fighting and military operations. Making effective and timely use of all available, relevant knowledge is a major requirement for today’s police officers who strive to fight organized crime or resolve complex criminal acts under time pressure. As they share this knowledge integration challenge with many management contexts, the authors have examined the knowledge visualization practices of a leading regional police force (and of a military unit) to derive insights for corporate knowledge management. Design/methodology/approach – To examine the knowledge visualization practices of a leading regional police force, the authors have conducted on-site observations, focus groups and interviews, as well as site, document, tool and software analyses within the police headquarters. Findings – As one main result of their empirical investigation, the authors find that the police force’s practice of hybrid (i.e. digital and physical) knowledge visualization offers a useful strategy for corporate knowledge management as well. They also show how organizations can apply this dual approach to making knowledge visible, i.e. using sophisticated visualization software in combination with hands-on physical and permanently visible knowledge boards. Originality/value – They discuss how these two modalities can be combined to improve knowledge management and how this hybrid practice can be understood theoretically through the lens of boundary object theory. With this regard, this article also extends the boundary object theory by identifying nine dynamic qualities of collaborative visualizations. [ABSTRACT FROM AUTHOR]

A great corpus of studies reports empirical evidence of how information visualization supports comprehension and analysis of data. The benefits of visualization for synchronous group knowledge work, however, have not been addressed extensively. Anecdotal evidence and use cases illustrate the benefits of synchronous collaborative information visualization, but very few empirical studies have rigorously examined the impact of visualization on group knowledge work. We have consequently designed and conducted an experiment in which we have analyzed the impact of visualization on knowledge sharing in situated work groups. Our experimental study consists of evaluating the performance of 131 subjects (all experienced managers) in groups of 5 (for a total of 26 groups), working together on a real-life knowledge sharing task. We compare (1) the control condition (no visualization provided), with two visualization supports: (2) optimal and (3) suboptimal visualization (based on a previous survey). The facilitator of each group was asked to populate the provided interactive visual template with insights from the group, and to organize the contributions according to the group consensus. We have evaluated the results through both objective and subjective measures. Our statistical analysis clearly shows that interactive visualization has a statistically significant, objective and positive impact on the outcomes of knowledge sharing, but that the subjects seem not to be aware of this. In particular, groups supported by visualization achieved higher productivity, higher quality of outcome and greater knowledge gains. No statistically significant results could be found between an optimal and a suboptimal visualization though (as classified by the pre-experiment survey). Subjects also did not seem to be aware of the benefits that the visualizations provided as no difference between the visualization and the control conditions was found for the self-reported measures of satisfaction and participation. An implication of our study for information visualization applications is to extend them by using real-time group annotation functionalities that aid in the group sense making process of the represented data.

This study investigates the effects of the restrictiveness of visuals on the communication process and outcome in small groups. Visual restrictiveness is conceived as the constraints imposed by a graphic template on the process of knowledge work. Through an experiment with ninety six experienced professionals we test the impact of a medium and a high level of visual restrictiveness compared to a control condition. As predicted, the results show that a medium level of visual restrictiveness, embodied in a grid layout, leads to higher experience sharing effectiveness. The impact is mediated by the structural pattern of appropriation of the interactive graphical template (assessed with content analysis). The implications of this study include extending the benefits and applications of visual representations to support group communication and the development (and testing) of the concept of visual restrictiveness.
