The Swiss Chapter consists of researchers, educators, consultants, and practitioners in the corporate and public sectors. Approximately 110 people receive our e-mails and about twenty of them have paid our newly introduced membership fee so far. The number of participants in chapter meetings has been around ten ever since we first met in 2003 (although there are distinct oscillations). Additional activities involve enhancing academic and consulting competences as well as educational programs. Chapter meetings are organized where we usually combine a presentation about System Dynamics in action with the discussion of organizational issues. With such a structure we try to maximize the benefits of our members. Our key conclusion so far is that there are quite some people in Switzerland who deal one way or another with System Dynamics. Everyone in this heterogeneous group is ultimately motivated to reach his or her individual SD related goals. The value added by the Chapter lies in the provision of networking, learning and exchange opportunities.
