Proper quality measurement and evaluation as well as precise understanding of customer's requirements and quality characteristics are necessary in order to fulfill customer's satisfaction and quality assurance in software The ISO 9126 series, which is used for international standard in 1990's, defines 6 quality characteristics and 21 sub-characteristics as a standard, and provides the software quality model and 3 level hierarchical characteristic structure with the informative reference of 40 internal quality characteristics. However, the study of assigning priority (weight) methods for mam characteristics, sub-characteristics, and internal characteristics are a few, so it is not easy to use the ISO quality model in software industry. Moreover it is almost impossible to measure and evaluate all 40 internal quality characteristics, considering time and cost, and the measurement scope also depends on the required integrity level of software product. By using AHP, one of the multi-purpose decision making methods, this study presents a method of selecting internal quality characteristics, based on their weights, with a real industry example. Through this study, we can find the possibility of using the quality model in software industry.
