Nominal Group Technique
Nominal group technique (NGT) is a structured decision-making method that enhances brainstorming with silent idea generation followed by group discussion and ranked voting to prioritize ideas.
Explanation
The nominal group technique is a structured method for group decision-making that overcomes some of the common pitfalls of traditional brainstorming, such as groupthink, dominance by vocal participants, and social pressure. The process typically follows four steps: silent individual idea generation, round-robin sharing of ideas, group discussion and clarification, and individual ranking or voting.
By beginning with silent generation, NGT ensures that every participant has the opportunity to contribute ideas independently before being influenced by others. The round-robin sharing phase ensures all ideas are heard, and the subsequent discussion allows for clarification and elaboration. Finally, the voting phase provides a democratic way to prioritize ideas based on the collective judgment of the group.
NGT is particularly useful for risk identification, requirements prioritization, and resolving disagreements among stakeholders. It produces a ranked list of ideas that reflects the group consensus, making it easier to move forward with clear priorities.
Key Points
- •Begins with silent individual idea generation to prevent groupthink
- •Uses round-robin sharing to ensure all voices are heard
- •Includes group discussion followed by ranked voting
- •Produces a prioritized list reflecting group consensus
Exam Tip
NGT is the go-to technique when the exam describes a need to reduce the influence of dominant personalities and achieve a ranked, prioritized list of ideas.
