The one liner technique provides members of the group with a chance to find out what everyone else is thinking. Members get a number of abbreviated opinions instead of one or two long speeches. The one-sentence limit may seem like an imposition, but once this pattern is set, each person will make a point of being clear and concise. After a short discussion, ask for a quick show of hands to determine group support for proposed ideas, to decide what to do next, and so on. Even this minimal level of participation gives people the opportunity to express an opinion.
Buzz groups are subgroups.
They break the ice, generate ideas, and enable everyone to participate. In a buzz group session, about four to eight people talk for a short time on an assigned topic. A person should be assigned as recorder to make lists of the group's quick conclusions. The buzz groups then return to the main group with their ideas. Buzz groups can convene and reconvene, report, and report again many times.
