Nominal group technique

« Back to Glossary Index

Effective decision-making and collaboration are key to project success. 

One technique that has proven to be valuable in facilitating group decision-making is the Nominal group technique (NGT). 

This structured approach encourages participation, generates ideas, and prioritizes solutions. 

In this article, we will dive into the NGT and explore its applications, benefits, and steps for implementation.

What is the nominal group technique?

The NGT gathers input and makes decisions through a structured group process. 

It was developed in the 1960s by Delbecq and Van de Ven as an alternative to traditional brainstorming sessions, which often suffer from issues like domination by a few individuals or the suppression of ideas. 

NGT provides a framework that ensures equal participation and encourages individual creativity.

Now that we have a clear understanding of what the nominal group technique entails let’s explore the step-by-step process of how it works in practice.

How does the nominal group technique work?

The nominal group technique process involves the following steps:

  1. Problem definition: the facilitator presents the problem or question to the group, ensuring everyone understands it clearly.
  2. Silent idea generation: each participant independently generates ideas or solutions related to the problem. This is done silently to prevent bias or influence from others.
  3. Round-robin sharing: the facilitator goes around the group, allowing each participant to share one idea at a time. The ideas are recorded without discussion or critique.
  4. Group discussion: once all ideas have been shared, the facilitator encourages open discussion, clarification, and expansion. Participants can seek clarification or suggest improvements.
  5. Voting and prioritization: each participant is given a predetermined number of votes (e.g., stickers or points) and asked to vote for the most favored ideas. The facilitator collects the votes and identifies the top-ranked ideas.
  6. Final ranking: the facilitator presents the results, including the top-ranked ideas based on the votes. The group discusses and finalizes the decision-making process.

By implementing the nominal group technique, project teams can unlock several benefits stemming from its structured and inclusive process.

Benefits of the nominal group technique

The NGT offers benefits such as:

  • Equal participation: NGT ensures that all participants have an equal opportunity to contribute their ideas without fear of being overshadowed or dismissed.
  • Improved decision quality: the structured nature of nominal group technique allows for a comprehensive exploration of ideas and prevents premature evaluation, resulting in more informed and better-quality decisions.
  • Reduction of group biases: by initially generating ideas silently, NGT reduces the influence of dominant personalities and encourages individual creativity. This helps minimize conformity and groupthink.
  • Efficient use of time: NGT provides a systematic process for decision-making, preventing discussions from digressing and enabling the group to focus on generating viable solutions within a given timeframe.

Having explored the benefits of the Nominal Group Technique, let’s now examine its diverse applications in various project management scenarios.

Applications of the nominal group technique

NGT can be utilized in various project management scenarios, including:

  • Requirements gathering: when collecting project requirements, NGT helps ensure that all stakeholders have a voice, promoting a shared understanding and minimizing the risk of overlooking critical elements.
  • Risk identification: by employing NGT, project teams can identify and prioritize potential risks effectively, enabling them to develop appropriate mitigation strategies.
  • Solution evaluation: when evaluating alternative solutions, nominal group technique allows project teams to consider diverse perspectives and select the most favorable option based on objective criteria.
  • Issue resolution: NGT helps resolve complex project issues by systematically analyzing potential solutions and arriving at a consensus-driven decision.

By promoting equal participation, minimizing biases, and enabling comprehensive exploration of ideas, NGT empowers project teams to make informed decisions and achieve successful outcomes. 

Incorporating nominal group technique into project management processes can foster greater engagement, creativity, and efficiency, ultimately contributing to project success.
