World Café was designed as a process to facilitate large meetings, give people an equal voice and invite contributions from everyone.
Small groups sitting at café-style tables discuss a problem for a set time period. One person ‘hosts’ each table group. At a given signal, participants move to other tables where the host talks through the discussions of the last group. Either the same question is repeated or a related question is discussed. Repeat the process, collect the ideas, present them in plenary and rank the solutions the groups have produced.
