The Nominal group technique is a method of consensus building.[1][1]

Method

One summary of the method is below.[1]

  • "Participants spend several minutes writing down their views about the topic in question"
  • "Each participant, in turn, contributes one idea to the facilitator, who records it on a flip chart"
  • "Similar suggestions are grouped together, where appropriate. There is a group discussion to clarify and evaluate each idea"
  • "Each participant privately ranks each idea (round 1)"
  • "The ranking is tabulated and presented"
  • "The overall ranking is discussed and reranked (round 2)"
  • "The final rankings are tabulated and the results fed back to participants"

Effectiveness

Delphi vs. Nominal Group Technique

One comparison found consensus was closer in the NGT than in the Delphi method; no overall difference between groups in their concordance with research evidence; but the Delphi method was more reliable. [2] In this study, the NGT had group meetings whereas the Delphi was done entirely independently.

A systematic review found that both methods can improve group processes.[3]
