If you have ever tried to facilitate a large meeting you know how unruly they can get without proper facilitation. One of the techniques that skilled facilitators use to keep meetings on track and to identify troubled spots is to communicate with the group using hand signals. Like wise hand signals are a good way for the people to communicate without interrupting the flow of conversation. The signals need to be agreed upon at the beginning of the meeting. Seeds for Change has a chart that will help you learn some of the most commonly used hand signals. Adopting hand signals in your large meetings will enable you to keep your meetings moving along smoothly and (fingers crossed) eliminate the shouting!
