Which decision-making technique involves structured group experts answering questionnaires in multiple iterative rounds anonymously?

Explanation

• The Delphi Technique gathers expert consensus through multiple rounds of anonymous questionnaires managed by a central facilitator.
• Anonymity prevents dominant personalities from exerting undue influence or inducing groupthink during problem solving.
• In contrast, the Nominal Group Technique (NGT) involves face-to-face group meetings with silent idea generation and voting.
