On index cards, one each, write tasks, roles, resources, decision-making, access to information that go with each position in the organization. E.g., the production worker in the coop, the manager in the coop, the union steward, etc.
Draw one card for each position: steward, president, member, etc.
Line up the roles, resources, etc that belong to each position.
Then, re-distribute the roles, etc. in teams -- what is the best way to distribute roles, responsibilities, why? Are new positions needed? Are some existing positions superfluous?
