Nominal Group Technique (NGT) and Delphi Technique are structured group decision-making methods used to gather information and prioritize ideas.
Definition Nominal Group Technique (NGT)
The Nominal Group Technique (NGT) is a structured group decision-making process used to generate and prioritize ideas. It emphasizes equal participation, ensuring that all members contribute without the influence of dominant personalities.
Definition Delphi Group Technique
Delphi Technique is a structured decision-making and forecasting process that gathers input from a panel of experts anonymously. It uses multiple rounds of questionnaires to refine ideas and achieve a consensus without direct interaction among participants.
NGT is ideal for in-person, small group interactions with immediate results.
Delphi is suited for expert-driven, remote, and anonymous input that requires more time to achieve consensus.
