The Delphi method used for forecasting:

The Delphi method is a structured, interactive process that involves multiple rounds of questionnaires and feedback from experts. It is used to develop forecasts or opinions from a panel of experts in a specific field. The panel is asked to evaluate the responses from all participants and provide their opinions about the issues under consideration. Participants are allowed to revise their responses after each round of feedback in order to reach a consensus view. The Delphi technique helps to overcome biases and provides an accurate analysis or forecast by combining the judgments of expert panelists. This method is especially valuable when a research problem or outcome relies on subjective input and judgment.
