A "survey of buyer intentions" is most effective when?

A "survey of buyer intentions" is most effective when a high percentage of "I-intend-to-buy" respondents are likely to actually purchase the product. This option highlights the key purpose of conducting such surveys, which is to gauge not just the intention to purchase but the actual likelihood of conversion from intention to action.

If the survey indicates that a significant portion of respondents who express an intention to buy are genuine in their purchasing plans, it provides valuable predictive insights for sales forecasts, inventory management, and marketing strategies. This actionable data enables businesses to make informed decisions about product launches, promotional efforts, and resource allocation.

In contrast, the other options can present challenges or uncertainties that may not yield reliable data for forecasting sales. While first-time buyers, existing product presence, or brand loyalty can influence purchasing behavior, the most critical factor for the efficacy of a buyer intentions survey is the direct correlation between expressed intentions and actual buying actions.
