As a follow up to the CANUX conference, I received a set of UX Method Cards. They are used by usability professionals to facilitate thinking and inspire collaboration. Cool. But, a Fail on my part - I didn't know (or have forgotten) what Kano analysis is.
The Kano model offers some insight into the product attributes which are perceived to be important to customers. The purpose of the tool is to support product specification and discussion through better development team understanding. Kano's model focuses on differentiating product features, as opposed to focusing initially on customer needs. Kano also produced a methodology for mapping consumer responses to questionnaires onto his model.
