Sharon Fisher has spent 20 years creating teambuilding, community service, and icebreaker activities for groups. With the official title of “idea sparker” at Orlando-based teambuilding company Play with a Purpose, she has loads of experience with all types of meeting attendees. Here’s what she needs to know about yours to help you choose your perfect icebreaker:

1. What’s the overall personality blend of the group? Are they primarily extroverts or more naturally introverted? “A group of salespeople will do something more strange or extreme than a group of engineers,” she says. But she is quick to caution planners not to underestimate their participants. “Planners tell me all the time, ‘Oh, my people won’t do that.’ But you would be surprised.”

2. What is the setting? What else is happening at the function? Will people be eating, drinking, walking around?

3. What is the timing of the activity? Is it opening night, and people are just seeing each other for the first time since the last meeting? Or is it the second or third night and they’ve all had the chance to do their hugging and reconnecting?

4. Can we blend the activity into the overall program, so that it dovetails with another meeting element or with the meeting content? Would you like to create an activity that helps you build toward something? Or is this simply an activity to get people to break out of their cliques and talk to each other?

5. How much structure do you need? Do you prefer a free-flowing activity, where attendees can play or not, as it suits them? Or will it be more formatted, with everyone encouraged to take part?
