Verification of Requirement Analysis Method for System Based on ISO/IEC 9126 Six Quality Characteristics

In order to take the profit based on the success of new product development. It is very important to define the quantitative quality requirement of new system product during system design phase. For the purpose of define the target quality of product, the method of quantitative quality requirement definitions based on ISO/IEC 9126 quality model that includes six characteristics is widely recognized, which are defined from the view point of customer satisfaction. However, independency of each characteristic is not sure and the suitability of method by using these six quality characteristics for quality requirement is not certified statistically. In this paper, we propose the result of verification about effectiveness of quantitative quality requirement definition from the view point of six characteristics defined in ISO/IEC9126.
