Kano model is a theory developed in the 80’s by Professor Noriaki Kano and his colleagues of Tokyo Rika University. The Kano et al (1996) model of customer satisfaction classifies attributes according to how they are perceived by customers and the impact of customer satisfaction. The model is based on three types of attributes viz. (1) basic or expected attributes, (2) performance or spoken attributes, and (3) surprise and delight attributes.
