Sasha, there are three places to look:
1. Participate as though the way you participate might make a difference in how the meeting goes. Usually how we participate is heavily shaped by how we prefer to participate. That is, we do what is comfortable. If you stepped a bit outside of your comfort zone, would you participate differently?
• Clear set-up or introduction of the topic
• Broad participation
• Clear process for how the topic will be discussed
• Thorough wrap-up of the topic before the next topic is started
• Specific commitments to take action
Then, I think it’s useful to look at what other people might need. Start by getting to the meeting early and asking if the leader needs anything. Then pay attention to other people who are attending and see what you might do to enhance their experience of the meeting.
