This document discusses using multiple methods to evaluate product concepts, known as product market triangulation. For 7 diagnostic test product ideas, physicians provided feedback through a Likert scale of individual concepts, forced ranking of all concepts, and a conjoint analysis of attribute utilities. While preferences varied across the methods, concepts C and E emerged as the most robust options, though neither was a strong favorite. Considering additional factors like primary care versus specialty use revealed further differences in physician preferences.
