Purpose
– Kano’s model is extensively applied in industry and by researchers. However, the model
has a shortcoming in that enterprises cannot use it to evaluate the influences of quality attributes on
product precisely; the lack of consideration of the different attribute strengths among 25 possible
outcomes affects judgment of the categories in Kano’s evaluation sheet. The aim of this study is to
measure the quality attribute strength of 25 possible outcomes in the evaluation sheet to develop a new
Kano’s evaluation sheet to improve the accuracy of the classification of the quality attributes.
Design/methodology/approach
– This study develops a new Kano’s evaluation sheet, and defines
the canonical and non-canonical judgment of the evaluation sheet based on a novel “similarity”
calculation which calculates the response frequency and the distance between canonical judgment and
non-canonical judgment.
Findings
– Quality attribute strength is probed and compared with the traditional Kano’s evaluation
sheet. The new Kano’s evaluation sheet is more practical because it supports a precise judgment of the
category of quality attributes. Empirical results also demonstrate that the new Kano’s evaluation sheet
is practical.
Originality/value
– The new evaluation sheet presents not only a different logic of classification
and statistical method for analyzing quality attributes, but also reviewed judgments of the category of
quality attributes from Kano’s traditional evaluation sheet.
