The Kano Model is a theory of product development and customer satisfaction developed in the 1980s by Professor Noriaki Kano. It categorizes customer preferences into five categories: Must-be, One-dimensional, Attractive, Indifferent, and Reverse. This framework helps product developers to prioritize features based on how they are perceived by customers and their potential impact on customer satisfaction. The Kano Model is particularly useful for identifying features that can significantly enhance customer satisfaction without proportionally increasing costs.
