Jac A.M. Vennix received his Ph.D. from Nijmegen University and is currently full professor of research methodology at the Faculty of Management Sciences of Nijmegen University. He has conducted a large number of projects in a variety of organizations in the areas of system dynamics group model-building and (interactive) scenario construction. He has(More)
The authors use the term, “Group Model Building” (Richardson and Andersen 1995; Vennix 1996; 1999) to refer to a bundle of techniques used to construct system dynamics models working directly with client groups on key strategic decisions. We use facilitated face-to-face meetings to elicit model structure and to engage client teams directly in the process of(More)
Facilitated modelling is used in supporting the resolution of strategic issues mainly because it is expected to improve communication between decision makers, foster consensus and create commitment. Researchers in both the strategy and facilitated modelling fields call for more systematic research on how strategy development works in practice and how(More)
While the facilitated modelling literature recognises the importance of the group process within facilitated modelling workshops, published empirical research rarely examines their dynamic nature. In this paper, we address this gap in the literature in two ways. First, we propose to locate facilitated modelling workshops as the main focus of investigation,(More)
Many field studies are available that describe successful applications of model driven group decision support methodologies. However, these studies suffer from a potential bias of contextual factors. We aim at a more rigorous testing of the effectiveness of a particular model driven approach, Group Model Building (GMB). The purpose of our research is to(More)
This paper uses a case study of a multi-disciplinary colorectal cancer team in health care to explain how a model of performance measures can lead to debate and action in Soft System Methodology (SSM). This study gives a greater emphasis and role to the performance measures than currently given in typical SSM studies. Currently the concept of performance(More)
Empirical evidence on how cognitive factors impact the effectiveness of model-supported group decision making is lacking. This study reports on an experiment on the effects of need for closure, defined as a desire for definite knowledge on some issue and the eschewal of ambiguity. The study was conducted with over 40 postgraduate student groups. A(More)
In this paper we report if and how validation is integrated in the different participatory approaches in System Dynamics. After this we present an analysis of 86 case studies to create a picture of how validation is conducted and reported in the field. We found that validation is hardly described as an integrated part of any participatory modeling approach.(More)
