Introduce the exercise as one in which the dynamics of negotiation among members of a group become apparent. Divide the class into groups of three (two participants and one observer) for case studies 1 and 2. You need at least two groups. Distribute the accompanying background sheets and role-playing sheets to the participants and observers. Give each observer one copy of the observers’ instructions used in the previous exercise. Without letting the groups know that they are getting different instructions, give half of them copies of the accompanying bargaining instructions and the other half copies of the role reversal instructions.
