Why the Nominal Group Technique Works Better Than Traditional Brainstorming

The Nominal Group Technique is a structured decision-making method that gives everyone an equal chance to contribute before group discussion begins. By combining independent thinking, open discussion, and ranked voting, it reduces bias and improves participation. This guide explains how the technique works, its benefits, limitations, practical uses, and how it compares with traditional brainstorming for better team decisions.

Have you ever walked out of a meeting feeling like only two people made all the decisions? It’s a common problem. In many group discussions, the loudest voices get the most attention, while quieter team members keep their best ideas to themselves. As a result, good suggestions can be missed, and teams may settle on solutions that don’t reflect everyone’s input.

The Nominal Group Technique(NGT) offers a better way. It is a structured decision-making method that gives every participant an equal chance to share ideas before the group discusses and ranks them. By creating a fair and organized process, the NGT helps teams make better decisions, reduce bias, and build stronger support for the final outcome.

What is the nominal group technique?

The NGT is a structured decision-making method that helps groups generate ideas, discuss them fairly, and agree on the best solution. Unlike open discussions where a few people may dominate the conversation, NGT gives every participant an equal opportunity to contribute before ideas are evaluated. This creates a more balanced process and encourages input from everyone, regardless of their role or personality.

The method was developed to improve participation in group decisions by reducing bias and making sure valuable ideas are heard. Instead of jumping straight into discussion, participants first think independently, then share their ideas, clarify them as a group, and finally vote to decide which solutions should move forward.

Because every step follows a clear structure, teams can make more thoughtful and transparent decisions. The Nominal Group Technique is one of several methods used within a structured Collaborative Decision Making (Pillar) process.

How does the NGT work?

The NGT follows a clear step-by-step process that helps every participant contribute before the group makes a decision. By separating idea generation from discussion, it reduces the chances of louder voices influencing others too early. According to McKinsey, only 28% of executives say the quality of strategic decisions in their organizations is generally good, highlighting the need for more structured decision-making methods.

Here’s how the process typically works:

1. Present the problem. The facilitator introduces a clear question or challenge for the group to solve.
2. Silent idea generation. Each participant writes down their ideas without discussing them. This encourages independent thinking and helps reduce group bias.
3. Round-robin sharing. Team members take turns sharing one idea at a time until every suggestion has been recorded.
4. Group discussion. The group asks questions, clarifies ideas, and makes sure everyone understands each option. This stage is for understanding, not debating.
5. Anonymous or structured voting. Participants rank or vote on the ideas they believe offer the best solution.
6. Final ranking. The votes are counted, and the highest-ranked ideas become the group’s priorities.

For example, a product team deciding which customer request to build next could use this process to gather ideas from engineers, designers, marketers, and support staff before selecting the most valuable feature. By giving everyone an equal voice, the team is more likely to reach a balanced decision. Each stage effectively supports facilitating group decision-making practices.

When to use the nominal group technique?

The NGT works best when a team needs to make an important decision while giving everyone an equal opportunity to contribute. It is especially useful when different opinions need to be heard, priorities must be set, or the group wants to avoid one or two people dominating the discussion. Because the process is structured, it helps teams stay focused and reach a clear outcome.

Organizations use this method in many situations, including strategic planning, project prioritization, healthcare, education, product development, and community planning.

For example, a hospital may use the NGT to rank patient care improvements, while a product team can use it to decide which features should be developed first. Schools, nonprofit organizations, and local governments also use it to gather ideas fairly before making important decisions. Organizations often combine this approach with other Collaborative Decision Making Models (T1) depending on the problem.

Benefits of the nominal group technique

The NGT helps teams make better decisions by creating a fair and organized process. Instead of letting a few people control the discussion, it gives everyone an equal opportunity to contribute before ideas are evaluated.

1. Balanced participation

Every participant shares ideas independently before the discussion begins. This reduces the influence of louder voices and encourages quieter team members to speak up.

3. Better decisions with less bias

Because ideas are generated silently first, people are less likely to be influenced by the opinions of others. The group evaluates ideas based on their value instead of who suggested them.

4. Faster prioritization

Once ideas are shared, participants rank or vote on the options. This makes it easier to identify the strongest solutions without spending hours debating every suggestion.

5. Stronger engagement and buy-in

People are more likely to support the final decision when they know their opinions were heard. According to Gallup, only one in four employees feel their opinions count at work and are more likely to perform their best, showing why inclusive decision-making matters.

6. Clear documentation

The process naturally creates a record of ideas, discussions, rankings, and final decisions, making it easier to review outcomes later.

Together, these strengths help teams make decisions that are fair, transparent, and easier to put into action. These advantages reflect many of the Benefits of Collaborative Decision Making (T2) found in high-performing teams.

What are the limitations of the NGT?

The Nominal Group Technique creates a fair and organized decision-making process, but it isn’t the best fit for every situation. Teams should understand its limitations before choosing it for an important discussion.

Despite these limitations, the NGT remains an effective choice for many teams that need balanced participation and clear priorities. However, when participants can’t meet in person, or complete anonymity is important, some organizations choose Delphi Method Decision Making (T1) instead.

Nominal group vs brainstorming technique 

The NGT and traditional brainstorming both help teams generate ideas, but they follow very different approaches. One focuses on structure and prioritization, while the other encourages free-flowing discussion. The right choice depends on the team’s goals, the type of problem being solved, and how much structure the discussion requires.

If a team needs to rank ideas, reduce bias, and ensure everyone contributes, the NGT is often the better option. On the other hand, brainstorming works well when the goal is to generate as many creative ideas as possible without following a strict process.

Neither method is universally better than the other. The most effective approach depends on the decision being made, the size of the group, and the level of collaboration needed. Choosing between structured and open discussions often depends on the team’s goals, much like deciding between the Delphi Method vs Nominal Group Technique (comparison).

Tips for running an effective NGT session

A well-planned session can make the difference between a productive discussion and one that feels rushed or disorganized. While the NGT follows a structured process, a few simple practices can help teams get better results.

1. Start with a clear question. Make sure everyone understands the problem before ideas are generated.
2. Set realistic time limits. Give participants enough time to think independently without letting the session lose momentum.
3. Encourage equal participation. Invite everyone to contribute and make sure each idea receives the same level of attention.
4. Stay neutral during discussions. Facilitators should guide the conversation without influencing how participants think or vote.
5. Document the final decision. Record the ideas, voting results, and action items so the team has a clear reference after the meeting.

Following these simple steps helps teams run smoother sessions and makes it easier to turn decisions into action. Many facilitators also use Decision Management Software (supporting) to capture ideas, record votes, and document final decisions.

Real-world example of the nominal group technique

Imagine a product team deciding which customer feature to build next. Instead of opening the floor for discussion, the facilitator asks everyone to write down their ideas independently. Giving each person time to think first helps surface a wider range of ideas and keeps louder voices from shaping the conversation too early. That structure matters because 93% of executives believe teams could achieve similar outcomes in half the time if they collaborated more effectively.

The team then shares each idea one at a time. After discussing the suggestions for clarity, everyone votes privately to rank the features. The feature with the highest score is selected for the next product release.

By hearing every idea before the discussion begins, the team chooses the feature based on its value rather than who suggested it. The result is a decision that is fair, practical, and easier for the entire team to support.

Conclusion

The Nominal Group Technique is not about making meetings longer. It is about making them fairer, more focused, and more productive. By giving everyone an equal chance to share ideas before discussion begins, teams can reduce bias, identify the strongest solutions, and make decisions with greater confidence. Whether used in business, healthcare, education, or community planning, this simple method helps groups reach practical decisions that people are more likely to support and act on. When every voice is heard, better decisions often follow.
