This document describes an exercise called "The Treasure, the Pirate and the Key" meant to promote discussion and consensus building. Participants are each given a copy of a key and must design the key that will unlock a treasure chest. Two example treasures are provided: future generations understanding the Red Cross, and human contentment. Participants then work individually and in groups to determine the top seven priorities, or teeth of the key, that would unlock the treasure. Groups discuss their priorities and a larger consensus may be reached. The exercise aims to explore differences in perspectives and the process of communication and consensus building.
