Product Selection via clever Questioning
Other companies also have software technologies to aid product selection. These technologies pose a series of questions to the buyer and deduce buyer preferences from the answers. Various schemes rely on various styles of questions, such as pairwise comparisons, ranking the importance of features, or weighing dimensions on a scale of 1 to 10. A host of theoretical frameworks underpin these tools, including statistical decision theory, fuzzy logic, utility theory, and optimization theory. Each tool strives to derive the best product recommendation from the fewest questions.
