Purpose: This study is aimed to introduce the OPA-Kano method, an integrated version of OPA(Originality
Practicality Analysis) and Kano's customer satisfaction method, and to examine its applicability.
Methods: 30 ideas for smart phone accessories are generated using brainstorming and SIT(Systematic
Inventive Thinking) and they are analyzed through the OPA-Kano method. For analysis, correlation method
between OPA and Kano's results is applied for the ideas.
Results: The results show that there is significant correlation between the OPA and Kano's approach, and
the effectiveness of the proposed method is verified through the case of smart phone accessories.
Conclusion: From the result of this study, we conclude that the proposed OPA-Kano method can be used
for the evaluation of ideas and customer satisfaction.
