Behavioural Issues in Model-driven Group Decision Support
Stream Organiser: L. Alberto Franco
Model-driven group decision support (GDS) is an approach to facilitating group decision making in which a formal, transparent model serves as the central mechanism for structuring discussion, enabling negotiation, and supporting analysis. In this approach, the model—rather than technology or social process alone—is the primary vehicle through which participants collectively explore, understand, and reach agreement about a problem situation.
This stream invites contributions that examine behavioural issues related to the design, use, and evaluation of model-driven GDS in both laboratory and field settings. Central to the stream is a focus on understanding what people actually do when they engage with model-drive GDS methods, procedures, and tools, and how their behaviours, cognitions, and emotions shape—and are shaped by—the use of such approaches.
We particularly welcome empirical studies that report on the application of model-driven GDS with face-to-face or virtual teams working on:
- Cross-functional and interdisciplinary decision making
- Strategy and policy analysis and evaluation
- Inter-organisational collaboration and partnership working
The stream also seeks contributions that advance theoretical and practical understanding of model-driven GDS approaches. Topics of interest include, but are not limited to:
- Problem structuring methods (e.g. SODA, SSM, Strategic Choice)
- Facilitated modelling approaches (e.g. Group Model Building, Decision Conferencing)
- Games and simulation-gaming approaches for group decision support
- The role of technology in supporting model-driven GDS
Finally, we welcome research that examines the development of competences and skills required for effective model-driven GDS, including facilitation, modelling and the management of group dynamics.
