Hand out a set of delegation cards to each participant. Introduce the cards: E.g. delegation is not black and white. Mandate can be moved to a team step by step while they get more used to/skilled at making various decisions.
This is the documentation after one session where a development manager wanted to clarify team mandates. The green mark is what the development manager wanted, the happy face is what the team wanted/agreed to.
Note that in all but one case, the team did not yet agree to take on the responsibility desired by the manager. In just one case the team did not get the level of mandate they wanted.
