The Kano model classifies product or service attributes based on the perception of the voice of the customer. There are three classifications (basic needs, performance, and excitement) which are useful for guiding design decisions in that they are an indication of when good is good enough, and when more-is-better.
Use: The Kano model’s main objective is to help teams uncover, classify, and integrate three categories of customer needs and attributes into the products or services that are being developed. The three types of needs are classified depending on their ability to create customer satisfaction (or cause dissatisfaction.) Missing any of these needs will jeopardize the success of the offering.
