Solution?
Research question
H1. Quantity


H2. Variety


H3. Recall


H4. Satisfaction

Hypotheses
Q A
Experiment
Subjects: 131 managers (in executive courses)
Groups of 5 = 26 groups
Knowledge sharing: discuss strategy implementation problems
3 conditions: control + 2 visuals
Control:
flipchart
Treatment 2:
timeline
Treatment 1:
visual metaphor

> Group meetings
> Conceptual visualization
- quantity of shared information (H1)
- variety (H2)
- recall (H3)
But subjects are not more satisfied
Interactive visualization is objectivey better than text, never worse!

Bresciani S., Eppler M., (2010). Choosing Knowledge Visualizations to Augment Cognition: the Managers’ View.

The use of an interactive visualization for facilitating group information sharing, compared to a plain paper support, has a positive impact on:
of shared information
of shared information
of shared information
with process and with outcome
(Reinig et al., 2006)
(Paivio, 1969)
(Briggs et al., 2006)
(Reinig et al., 2006)
Experimental treatments:
interactive visualization
subjective measures
objective measures

Using an interactive visualization for facilitating group information sharing, compared to a plain paper support, leads to:
pca, reliability
Multilevel ANOVA to account for group-level variance

Treatment model:
Yij= β0+ β1 X1 + β2 X2 + U0j + e0ij
p<.05, 2-tailed
p>.05, 2-tailed
Theory
Practice
Analysis:
Does interactive visualization
enhance knowledge sharing
compared to text based methods?
In face to face meetings in organizations
hidden effect of visualization
Different visual formats lead to similar performances
Information visualization + management information systems (GSS)
Dual Coding Theory (Paivio, 1969) applied to collaborative settings
"Representational guidance" applied in organizations
easy to implement, nothing to loose!
Visualization in general is better than text
Theoretical background:
Information visualization + Management Information Systems
Dual Coding Theory (Paivio, 1969)
Representational guidance (Suthers & Hundhausen, 2003)
Call to action:
role of shared drawings in GSS (Briggs, Nunamaker & Sprague, 1998)
Group Support Systems
Collaboration engineering (Briggs, Vreede & Nunamaker)
- satisfaction (H4)
Adaptive Structuration Theory (DeSanctis & Poole, 1994)
