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).
