Final answer:
The Delphi method is the subjective forecasting technique that uses the anonymous opinions of a panel to predict future sales. It is distinct from quantitative methods such as moving averages, exponential smoothing, and regression analysis, which are founded on historical data and statistical modeling.
Step-by-step explanation:
The subjective forecasting method that depends on the anonymous opinion of a panel of individuals to generate sales forecasts is known as the Delphi method. This approach involves several rounds of questioning, where the identities of the participants are not revealed to each other. Each round results in a summary of the forecasts and the reasons the participants provided for their judgments. These summaries are then used to refine the forecasts in subsequent rounds, with the aim of reaching a consensus. Methods like moving average and exponential smoothing are quantitative, relying on historical data rather than opinions. Regression analysis involves a statistical approach to model the relationships between variables.
