People are involved and interested, and there are no signs of boredom. Lots of discussion in which most people participate. Discussion is relevant to group task. Someone always brings the discussion back to the topic when the group gets off subject. Group objective was frequently reached by consensus.
Members listen to one another.
Discussion tends to stay on track, without jumping to unrelated topics. All ideas are heard. Group is comfortable with disagreement. Group does not avoid conflict. Disagreements are not suppressed or overridden by premature group action.
