Conjoint analysis is a technique used to understand how consumers develop preferences for products and services. It involves presenting respondents with profiles consisting of different attribute levels and measuring their preferences. The preference data is then analyzed, usually via regression, to estimate the part-worth or utility that respondents associate with each attribute level. These utilities can then be used to simulate market shares of potential new products and identify key drivers of preferences. Conjoint analysis sees wide commercial use across various industries to guide new product design and selection.
