Nominal Group Technique

André Delbecq & Andrew Van de Ven, 1968

The Nominal Group Technique structures idea generation as silent individual writing, round-robin sharing, group clarification, and anonymous voting — preventing dominant voices from determining outcomes before the data has a chance to speak.

// description

The Nominal Group Technique (NGT) is a structured decision-making method that begins with silent individual idea generation, moves to round-robin sharing, proceeds to group discussion for clarification, and concludes with anonymous voting or ranking. The word "nominal" reflects the fact that participants function as a group in name only during the ideation phase, preventing groupthink and anchoring.

// history

Delbecq and Van de Ven developed NGT in 1968 while researching program planning at the University of Wisconsin. They were looking for a method that captured the benefits of group interaction without the well-documented downsides of unstructured discussion, where dominant personalities tend to steer outcomes. The technique became widely used in healthcare, social services, and public policy settings where equitable participation matters.

// example

A small KDP team uses NGT to decide which new product category to enter. Each team member silently writes their top three category ideas. During round-robin, 14 distinct categories emerge. Discussion clarifies overlaps and surfaces concerns. Anonymous dot voting reveals "activity books for seniors" and "profession-specific planners" as clear winners, despite the most vocal team member having championed "pet memorial gifts" throughout. The anonymous structure lets data speak without deference to whoever is most enthusiastic in the room.

This is the method to use when you're co-creating with people who have very different experience levels or personality types — like when you're getting input from your community on what course to build next. The silent generation phase stops your most enthusiastic members from anchoring everyone else's thinking. I've used a simplified version in community surveys: ask everyone to submit their top three product ideas privately, then aggregate and share results before any discussion. The results are always more diverse and more interesting than what emerges from open conversation.

Design a Nominal Group Technique session I can run asynchronously with my [community / email list / mastermind group] to decide [the decision — e.g. "which course topic to build next" or "which product direction to take"]. Write the exact survey or form questions, explain how to aggregate and present results anonymously, and draft the follow-up message sharing results before discussion. Keep it completable in under 5 minutes for participants.
I want to use Nominal Group Technique principles to get better product feedback from my audience without the loudest voices dominating. My audience is [describe — e.g. "KDP creators in a Facebook group"] and I'm trying to decide between [list 3–5 options]. Write me the exact poll or survey structure, explain how to run the clarification and voting phases, and tell me how to interpret and act on the results.
Simulate a Nominal Group session for me as a solo practitioner. I'm trying to decide [your decision — e.g. "which niche to enter next" or "how to structure my next digital product"]. Play the role of three different types of advisors — a conservative one, an experimental one, and a market-data-driven one — have each generate their top three ideas silently, then aggregate the nine ideas, flag the ones that appeared more than once, and give me a ranked list I can use as my decision input.
