Conjoint analysis is an approach used to achieve preference$-$based segmentation by:

forcing customers to make trade$-$offs between pairs of offerings with different attributes

forcing customers to articulate why they make certain purchases based on each attribute, one at a time

correlating preference data with response data

forcing customers to rank each attribute on a scale of $1-10$ based on their preference for that attribute

extending the multi$-$attribute model approach to new product categories
