This is suitable for groups of up to 15 people and is usually done the first time they meet as a group be it the beginning of the season or the beginning of a week long retreat or holiday. It acts as a way to get to know each other quickly, a forum for people to acknowledge what they are excited about and what they are anxious about, what they can give to the group and what they hope to receive from the group. They then have an opportunity to make a working contract together which may be simple house rules that they all agree to adhere to or can be more complex incorporating various different aspect of your particular company or retreat.
