Abstract: This study proposes two new methods to familiarise respondents with innovative attributes and thereby ensure their stable preference statements within customer tests in the product development process. These warm-up phases differ in how the participants gather information about the product category, namely, independently or in the lab. A qualifying examination tests the appropriateness of study participants as respondents in a following preference measurement task. Both approaches effectively prepare respondents, though the independent search version offers slight advantages. Our study offers useful tools for evaluating the warm-up phases of preference measurement studies.

Keywords: preference measurement; innovative attributes; product development; product innovation; warm-up phases; product preferences.
