Which method collects opinions from an anonymous panel of experts multiple times to reach consensus?

The Delphi Method is a structured communication technique that seeks to gather the insights and opinions of a panel of experts through a series of questionnaires. Initially, participants provide their opinions anonymously, which helps to prevent bias and encourages honest feedback. After the first round of responses, a facilitator summarizes the findings and shares them with the group, allowing for further rounds of questioning and discussion.

This iterative process continues until a consensus is reached among the experts. The emphasis on anonymity helps to mitigate the influence that one individual's opinion might have on others, fostering a more genuine exchange of ideas. The Delphi Method is particularly useful in areas where uncertainty is high, and collective expertise can lead to more accurate forecasts or assessments.

The other options do not involve this multi-round process of anonymous feedback and consensus-building characteristic of the Delphi Method. For instance, Historical Analogy pertains to drawing parallels from past events rather than gathering expert opinion. Hands-On Training focuses on experiential learning rather than opinion gathering, and Seasonal Effects are related to changes based on different times of the year without a focus on expert consensus. Thus, the Delphi Method is clearly the appropriate choice for collecting and reaching consensus through expert opinions.
