A correlation comparison with other priority methods such as Bacon( 2003)'s model and Matzler and Hinterhuber(1998)'s QI index is conducted. Results:The priority results by the proposed method shows better in correlation coefficient with customer perceived priority for improvement than other methods. Conclusion:From the result of the current study, it can be concluded that the result of the proposed method is valid, while it is relatively easy to understand and analyze, and therefore no additional survey is necessary for improvement priority.
