System Dynamics Glossary

What is the meaning of Modeller / reflector?

The modeller (or reflector) focuses not at all on group processes but rather on the model that is being explicitly (and sometimes implicitly) formulated by the facilitator and the group. The modeller / reflector serves both the facilitator and the group. He thinks and sketches independently, reflects information back to the group, restructures formulations, exposes unstated assumptions that need to be explicit, and in general serves to crystallise important aspects of structure and behaviour. Richardson and Anderson stress that in their experiments, it was found necessary for both the facilitator and the modeller / reflector to be experienced system dynamics modellers (Richardson and Andersen (1995: 113-137).
