Which of the following is a qualitative forecasting method?

• A. Trend projection.
• B. Delphi method.
• C. Naive approach.
• D. Linear regression.

Answer: (B)

The Delphi method is a qualitative forecasting technique that relies on the input and insights of a panel of experts. This approach systematically gathers opinions and forecasts from a group of knowledgeable individuals, often through multiple rounds of anonymous questionnaires. The aim is to achieve a consensus on future events or trends by allowing experts to refine their views based on the feedback of others and the aggregate responses.

Qualitative methods like the Delphi method are particularly useful in situations where historical data may be limited or non-existent, such as predicting the acceptance of a new product or technology. The focus here is on judgment and subjective assessments rather than purely numerical analysis, which distinguishes this method from quantitative forecasting techniques like trend projection, naive approaches, or linear regression, all of which rely heavily on existing data and statistical calculations.
