This document discusses concept value testing using the Kano model. It provides an overview of what concept value testing is and is not, explaining that it is a way to prioritize concepts with customers, refine a roadmap, and quantify customer value. It then describes the Kano model, created by Professor Noriaki Kano, which classifies concepts into five categories - performing, must-have, attractive, indifferent, and dissatisfying - based on customer responses. It shows how the Kano questionnaire works and how the results can be charted and visualized to understand concept performance.
