what group coaching models do you know/use?

[car...@authenticityconsulting.com]

Over the years, clients have been asking for more group coaching models.  I confess that my knowledge of them is a bit stale. 

By the phrase "coaching models", I mean a structure for guiding the questioning/coaching in a group, for example, to ask questions generally in the order of:

1. Head, Heart, Hands (or Think, Feel, Do)

2. ORID - objective, reflective, interpretive and directive types of questions

3. WIAL - reporting, clarifying, strategizing, action planning, and learning

4. GROW - goals, reality, options and will/actions

What other models have you used in groups?

Thanks!
