The purposes of this study were to analyze importance and performance for coffee quality attributes based on customers according to their consumption types; and provided ideas and marketing strategies to increase sales through IPAs (Importance-Performance Analysis). University students in Incheon were conducted a survey from March 13, 2007 to March 31, 2007. As for a quality attribute with the highest importance, the survey showed 'price' was important for 「vending machine coffee」, and 'taste' was important for 「commercial coffee」, and 「coffee house coffee」. And 'thirst relief' was found to have the lowest importance for three types of coffee. As for a quality attributes with the highest performance, the survey showed 'taste' was important for 「coffee house coffee」 'price' was important for 「vending machine coffee」; and 'period of circulation' was important for 「commercial coffee」. IPA results for coffee quality attributes also showed quality attributes that should be improved quickly for each type of coffee: 'hygiene', 'safety', 'period of circulation', and 'package' were for 「vending machine coffee」; 'price' and 'freshness' were for 「commercial coffee」; and 'price' and 'period of circulation' were for 「coffee house coffee」.
