Identification of functional requirements
The A-Kano model requires the survey results of customer’s satisfaction using
the Kano questionnaire. In general, the questionnaire is designed according to
a set of CNs. To allow for unambiguous understanding, the CNs are translated
into FRs, Fhffiji ¼ i; 2;.; Ig. For example, visibility of the gauges in a car
dashboard is a CN, and is manifested by the size and lighting conditions of
the gauges, namely the FRs. In this research, the FRs are typically related
to customizable product attributes from which the customers can choose
according to his/her preferences.
