CAPM · Question #491
Which characteristic defines the Delphi technique of group decision-making?
The correct answer is B. The participants must use their expertise to determine the best option. The Delphi technique is a structured expert consensus method where participants independently apply their expertise across multiple anonymous rounds until agreement is reached.
Question

Why each option
The Delphi technique is a structured expert consensus method where participants independently apply their expertise across multiple anonymous rounds until agreement is reached.
Eliminating options based on cost is a constraint-based filtering approach and does not describe the Delphi method.
In the Delphi technique, a panel of subject matter experts uses their domain knowledge to evaluate options or provide estimates anonymously; results are aggregated and fed back iteratively until the group converges on a consensus. Expertise - not cost filters or voting algorithms - is the foundation of the decision.
Creating a ranked list and voting describes the nominal group technique, not the Delphi technique.
Using a predefined algorithm and scoring system describes a weighted criteria or decision matrix approach, not the Delphi technique.
