Nominal Group Technique (NGT) finds utility across various industries such as healthcare, technology, education, and product design, particularly during the early phases of innovation and project development when teams seek to harness diverse perspectives and prioritize concepts. This structured approach can be particularly beneficial during brainstorming sessions held to identify new products, features, or improvements to existing offerings. Participants, typically comprising a cross-functional team including engineers, designers, market analysts, and stakeholders, engage in a round-robin format which serves to level the playing field, ensuring that quieter members have an opportunity to voice their ideas without being overshadowed by more dominant personalities. The emphasis on anonymity in the initial idea generation phase minimizes peer pressure, allowing for a broader range of thoughts that might otherwise remain hidden in traditional brainstorming settings. Following the sharing of ideas, the subsequent discussion phase allows participants to seek clarification, build upon suggestions, and refine their understanding before voting on the proposed solutions, which leads to the identification of those with the highest consensus among the group. This technique not only promotes collaboration but also results in actionable outcomes that have been synthesized from group input, making it suitable for complex design challenges where stakeholder buy-in is critical to the success of the project. Furthermore, NGT can be effectively employed in strategic planning sessions and focus groups, facilitating a democratic process that prioritizes ideas based on collective agreement, thereby paving the way for innovative breakthroughs in product development and organizational strategy.

Key steps of this methodology

  1. Participants generate ideas individually in writing.
  2. Ideas are shared one by one in a round-robin format.
  3. Each idea is discussed and clarified by the group.
  4. Participants individually rank or vote on the ideas.
  5. The rankings are tallied to prioritize ideas.

Pro Tips

  • Encourage participants to draft multiple ideas initially, as this can stimulate deeper thinking and prevent fixation on a single concept during discussion.
  • Use anonymous voting methods for ranking to minimize bias and influence from dominant personalities, leading to more honest feedback.
  • Implement time limits for each stage—idea generation, discussion, and voting—to maintain a dynamic pace and maximize engagement from all participants.
