Here at Impact First we use the 'Diamond 9' technique to support groups of people in developing a shared understanding of words/concepts, which are important to their work. Wherever you need to facilitate a group with the aim of discussing key concepts and prioritising them try this four stage approach:
Brain storm (as a large group) the key phrases / concepts for whichever topic you're discussing e.g. how can we bring our team vision alive or which values which underpin our work. Alternatively use a predetermined taxonomy like essential behaviours of a coach as defined by John Whitmore.
In smaller groups of three or four people, select the nine things, which the group thinks are the most important. It is the discussion this generates, which is the most important thing here. In selecting the 'top nine', groups have to share what each means and why they feel it should be included.
The small group then has to order the factors / characteristics into a diamond shape with the most important towards the top and the least important towards the bottom (see template attached). Again, this generates more discussion and develops shared understanding as well as a priority list.
Encourage the small groups to share their diamond 9s with each other, justifying why they put a particular factor / characteristic at the top.
