KANO Model

The KANO model was proposed by Japanese scholar Noriaki Kano to analyze the nonlinear relationship between customer needs and satisfaction. In foreign trade customer management, this model divides customer needs into five categories: basic needs (must-have; if unmet, extreme dissatisfaction; if met, no delight), performance needs (satisfaction is proportional to fulfillment), excitement needs (exceed expectations and bring delight), indifferent needs (presence or absence does not affect satisfaction), and reverse needs (fulfillment actually causes dissatisfaction). Use cases include: customer satisfaction surveys, product feature prioritization, differentiated service design, and customer tiering management. Note: need classification must be determined through questionnaires and data analysis; classifications may differ across markets and customer types; adjust dynamically because needs transform over time (e.g., excitement becomes performance, then becomes basic). Difference from the RFM model: RFM focuses on customer value tiering, while KANO focuses on the relationship between need attributes and satisfaction. Foreign trade practitioners can use the KANO model to optimize customer experience and enhance loyalty.
