Overview
The Nominal Group Technique (NGT) is a structured decision-making and problem-solving method designed to maximize individual participation while ensuring that group discussions remain focused and productive. Developed by Andre Delbecq, Andrew Van de Ven, and David Gustafson in 1975, NGT was originally intended for strategic planning and policy development but has since been widely applied in business, healthcare, education, and community engagement. The technique is particularly useful when groups need to prioritize ideas, reach consensus, or generate creative solutions without being influenced by dominant voices.
Unlike free-flowing brainstorming sessions, where extroverted or senior individuals may dominate discussions, NGT ensures equal contribution from all participants by structuring the process into distinct phases. The process typically includes four key stages:
Silent Idea Generation – Participants individually write down their ideas in response to a specific question or problem. This prevents groupthink and allows for independent thought.
Round-Robin Sharing – Each participant shares one idea at a time in a structured way, ensuring all voices are heard. These ideas are recorded on a flip chart or digital board without discussion.
Clarification and Discussion – Participants collectively review and refine the ideas, clarifying their meaning and combining similar suggestions.
Voting and Prioritization – Participants rank or score the ideas based on importance, feasibility, or impact. The group decision is then derived from these individual rankings.
At the end of the process, the group has a prioritized list of ideas that reflects the collective input of all members, eliminating biases related to status, loudness, or persuasion skills. This makes NGT particularly valuable in settings where fairness, inclusivity, and objectivity are critical, such as policy development, curriculum design, employee engagement, and strategic decision-making.
Why the Nominal Group Technique Matters Today
Organizations today face increasing complexity, requiring collaborative and structured approaches to decision-making. NGT is particularly relevant in the current landscape for several reasons:
Diverse and Hybrid Workforces: In organizations with multicultural, remote, or hierarchical teams, ensuring that every voice is heard is challenging. NGT provides a mechanism to level the playing field, making it easier to integrate diverse perspectives.
Rapid Decision-Making Needs: While brainstorming sessions can be chaotic, NGT provides a structured and efficient way to gather input and prioritize action, reducing the time spent on debates.
Data-Driven and Transparent Decision-Making: With an emphasis on quantifiable ranking, NGT produces decisions backed by measurable group consensus, which is essential for credibility and accountability.
Conflict Management and Consensus Building: In situations where groups face tension or disagreement, the structured nature of NGT prevents dominant personalities from overshadowing others, making it easier to navigate complex issues without escalating conflict.
Addressing Cognitive Biases in Decision-Making: Psychological research has shown that traditional group discussions often fall victim to groupthink, confirmation bias, and anchoring bias. NGT mitigates these risks by structuring participation and reducing interpersonal influence.
Conclusion
The Nominal Group Technique is more than just a decision-making tool—it is a powerful method for democratizing discussions, fostering inclusivity, and driving meaningful outcomes. Whether used in business, education, healthcare, or policymaking, its structured approach helps organizations turn group ideas into action without the common pitfalls of group dynamics.

Facilitation
Facilitating the Nominal Group Technique Step-by-Step
A skilled facilitator plays a crucial role in ensuring that the Nominal Group Technique (NGT) is executed effectively. NGT follows a structured and disciplined process that balances individual thinking with group collaboration. Below is a detailed facilitation guide.
Step 1: Preparing for the NGT Session
Objective: Ensure the session is well-structured and participants understand the process.
Define the Focus Question: Clearly articulate the issue the group will address. Example: “What are the top priorities for improving employee engagement in our organization?”
Gather Supplies:
Flip chart or whiteboard
Index cards or sticky notes
Pens or markers
Set Up the Room:
Arrange seating in a U-shape or circle to promote inclusivity.
Ensure participants cannot see each other’s notes during idea generation.
Establish Ground Rules:
Equal participation is required.
No criticism or debate during idea sharing.
Ideas will be ranked based on group consensus.
Step 2: Silent Generation of Ideas
Objective: Allow individuals to develop ideas independently before group discussion.
Present the problem statement clearly, both verbally and in writing.
Give participants 5–10 minutes to silently write down their ideas on index cards.
Encourage them to write one idea per card and avoid discussion.
Facilitator’s Script: "Take the next few minutes to think about this issue and write down your ideas. Each idea should be short and clear, and please work independently without discussing with others.”
Step 3: Round-Robin Recording of Ideas
Objective: Ensure every idea is shared and documented without bias.
Each participant shares one idea at a time while the facilitator records it on a flip chart.
Repeat the process until all ideas are shared.
No discussions or evaluations at this stage.
Facilitator’s Script: "We will now go around and share one idea at a time. I will record each idea exactly as you state it. If someone shares an idea similar to yours, you can still share your variation."
Step 4: Discussion and Clarification
Objective: Allow participants to refine and better understand all ideas.
Ask participants to explain unclear ideas (but not defend them).
Merge duplicate ideas where appropriate.
Encourage brief discussions but prevent debates.
Facilitator’s Script: "Now that all ideas are listed, let’s review them for clarity. If you have questions about an idea, now is the time to ask for clarification.”
Step 5: Voting and Prioritization
Objective: Rank ideas based on individual scoring.
Participants privately select their top five ideas and assign scores:
5 points for the most important idea
4 points for the second most important idea
3, 2, and 1 points for the remaining choices
The facilitator collects all votes and tallies scores to determine the top ideas.
Facilitator’s Script: "Look at the list of ideas and select the five you feel are most important. Rank them from 5 (most important) to 1 (least important). Afterward, I will total the scores to identify the group's top priorities."
Step 6: Reviewing and Finalizing Results
Objective: Present and confirm the prioritized list.
Write down the total scores for each idea.
Announce the top-ranked ideas based on group voting.
Facilitate a brief discussion to ensure consensus and finalize action steps.
Facilitator’s Script: "Based on our voting, here are the top priorities. Do these results align with your expectations? Are there any additional insights before we finalize our action steps?"
