World Café is a very effective moderation method suitable for groups of 12 or more. Conversations are held in a pleasant atmosphere. Just like in a café tables are prepared for 4-5 people each. As tablecloth flipcharts are placed over the tables and enough drinks and glasses are provided. Participants can doodle, draw and take notes on the flipcharts. Even people without a lot of experience talking in groups regularly feel very comfortable in this setting!
Ideally, there are 3 rounds of about 20-30 minutes, during which the participants can work on one or more complex and important questions. After each round a host stays at the table, all others move to different tables. The host introduces the newcomers to the results of previous rounds.
World Café is easy to perform, but at the same time very effective. It is suitable for groups of 12 people or more, the number of participants is limited only by the conditions of the premises. I have organized World Cafés in meetings of up to nearly 150 participants and when premises were limited sometimes in more than one room simultaneously.
