One major advantage of NGT is that it avoids two problems caused by group interaction. First, some members are reluctant to suggest ideas because they are concerned about being criticized, or are reticent and shy. Second, some members are reluctant to create conflict in groups. (Many people want to maintain a pleasant climate.) NGT overcomes these problems (e.g.). NGT has the clear advantage in ensuring relatively equal participation. It may also, in many cases be a time-saving technique. Other advantages include producing a large number of ideas and providing a sense of closure that is often not found in less-structured group methods.
