The document describes an exercise called the "pink elephant exercise" which was created by organizational theorist Chris Argyris. Participants are asked to make three confidential lists: issues they are happy to discuss about their team, issues they will never discuss, and issues they may discuss under certain circumstances. Teams then have 20 minutes to discuss how to move barriers between the lists, such as changing circumstances so more issues can be discussed. The goal is to identify and potentially address previously undiscussable issues that have hindered the team.
