What is the Delphi technique?

The Delphi technique is a systematic method for gathering expert opinions through structured questionnaires, making it an iterative process often used to achieve consensus among a panel of experts on specific issues or topics. This technique involves a series of rounds where experts respond to a questionnaire, and after each round, a summary of the group's responses is provided to all participants. The experts can then revise their earlier answers in light of the feedback, promoting deeper consideration of the topic and fostering group discussion without direct confrontation.

This method is particularly useful in fields such as policy-making, forecasting, and planning, as it allows for the collection of informed insights while minimizing the influence of dominant individuals over the group decision. By focusing on expert judgment and utilizing anonymity, it helps mitigate biases that might occur in face-to-face discussions, leading to a more comprehensive understanding of complex issues.

In contrast, the other options provided do not align with the core definition of the Delphi technique. For instance, the method for conducting experiments refers to empirical research designs, while a statistical analysis technique relates to data evaluation processes rather than expert consensus. A strategy for observational research emphasizes direct observation rather than structured feedback from experts. Thus, the choice emphasizing structured questionnaires for expert opinion is definitively representative of the Delphi technique.
