In an effort to forecast future sales of an existing product, a company is looking for detailed information to learn about its target demographic. Which method should the company use to gather this information?

While the Delphi technique is useful for gathering expert opinions through a series of questionnaires, it focuses more on consensus building rather than direct feedback from the consumer base. This method may not provide the specific insights needed to understand the target demographic's preferences regarding the existing product.

Analyzing sales force composition involves examining the demographics and characteristics of the sales team rather than the target customers. This method may provide insights into how well the sales team can promote the product, but it does not yield direct information about the preferences or opinions of the actual target market.

The jury of executive opinion method relies on the judgments of a group of executives to forecast future sales. While this can be useful for strategic planning, it does not capture the direct opinions of the target demographic. The insights from executives may be informed but lack the specific consumer insights needed for effective market forecasting.
