PMBOK (2004 3rd 英) P186 质量规划工具中提到了Nominal Group Analysis但是没有具体解释,下面是一些补充

This technique is a structured variation of small group discussion methods. The process prevents the domination of discussion by a single person, encourages the more passive group members to participate, and results in a set of prioritized solutions or recommendations (consensus). The steps to follow in NGT are:
  1. Divide the people present into small groups of 5 or 6 members, preferably seated around a table.
  2. State an open-ended question (" What are some ways we could encourage participants to car pool?").
  3. Have each Person spend several minutes in silence individually brainstorming all the possible ideas and jot these ideas down.
  4. Have the groups, collect the ideas by sharing them roundrobin fashion (one response per person each time), while all are recorded in key term, on a flipchart. No criticism is allowed, but clarification in response to questions is encouraged.
  5. Have each person evaluate the ideas and individually and anonymously vote for the best ones (for example, the, best idea gets Points, next best 4 Points, etc).
  6. Share votes within the group and tabulate. A group report is prepared, showing the ideas receiving the most points.
  7. Allow time for brief group presentations on their solutions.
这种方法与风险管理中的Delphi技术的目的一样 - 避免个人因素,达到一致意见(consensus)。不同的是实现方法,Delphi主要利用的是questionaire
