Conversation safeguards
Experience with SSD conversations has shown it useful to operate a system of "guarantors" to safeguard the process. Guarantors might be appointed (and rotated) to monitor adherence to:
The selected theme
Opportunity for equal participation
Honouring diversity and every contribution made
Developing team rules and spirit
Establishing common ground
Being open to emerging/new ideas
Shared leadership and other roles
Rotation of responsibility, hopefully by a system of individual volunteers, can provide an additional benefit of fostering personal development.
