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).
