Which method is designed for systematic, interactive forecasting using expert panels?

The Delphi technique is specifically designed for systematic, interactive forecasting by gathering insights from a panel of experts. This method involves iterative rounds of questionnaires combined with controlled feedback, allowing experts to provide their opinions and revise them in response to the collective feedback of the group. This process helps to build a consensus or identify divergent viewpoints regarding future events or trends.

In the Delphi technique, the anonymity of responses encourages participants to express their views without the influence of group dynamics, leading to more honest and potentially innovative forecasting. By reflecting on earlier rounds of responses, experts can refine their opinions, which enhances the accuracy and reliability of the forecast.

In contrast, focus groups tend to emphasize discussion among participants without the structured feedback mechanisms characteristic of the Delphi technique, which can lead to dominant voices overshadowing others. Horizon scanning generally involves identifying emerging trends and is less about consensus-building among experts. Brainstorming sessions focus on generating a variety of ideas and solutions in a more informal setting, rather than systematically forecasting future developments.
