Improving software product quality is a key to increasing user satisfaction and to achieving competitive edge. There are two approaches to assure high software product quality; development process-oriented and product-oriented. There have been many efforts for improving software quality through process certification, for example, CMM, ISO 9000 family, ISO/IEC 12207, SPICE and Bootstrap. However, a good process alone cannot guarantee good product quality. A need for the evaluation of software product quality by an independent third party is growing rapidly for several reasons. We are concerned with an application of Statistical Quality Control (SQC) to the evaluation of software product quality to obtain the efficiency of evaluation processes and the objectivity of evaluation results. Methods for selecting test cases using a random sampling approach have been discussed and methods for selecting acceptance criteria with respect to software product quality have also been suggested.

As the number of Internet users increases, online shopping malls are gradually flourishing and sales are continuously growing. However, since consumers are not able to check what they purchase when buying products on the Internet, they are bound to have higher risk perception than buying directly from off-line stores. Especially, sporting goods require a special attention because a preliminary test is important. Therefore, the risk perception is much higher when people purchase sporting goods online. This study first identifies the multi-dimensionality of risk perception. Then, it investigates whether online purchasing experience of sporting goods makes differences in the level of risk perception. In addition, it examines whether the risk perception by those who had an experience in purchasing sporting goods online affects the customer satisfaction. This study has identified five dimensions in the concept of risk perception, such as financial risk, performance risk, security risk, delivery risk, and psychological/physical risk. A statistical analysis shows that people without an experience in purchasing sporting goods online have perceived significantly higher performance risk, security risk, and psychological/physical risk than those with online purchasing experiences. Finally, this study has found that delivery risk, financial risk, and psychological/physical risk have significant negative influences on the customer satisfaction.
초고속 정보기반 응용서비스 확산 정책의 동태적 효과 분석 : 내생적 성장이론의 적용
김동주,임성택 정보통신정책학회 1998 정보통신정책연구 Vol.5 No.1
초고속 응용서비스 확산정책은 수요를 진작시키고 응용서비스 를 제공하는 기업의 이윤을 증가시킨다. 이러한 이윤의 증가는 보다 많은 연구· 개발로 이어져 새로운 정보통신 서비스 개발속도가 빨라질 수 있다. 그러나 응용서비스 의 공급이 증가하면 더 많은 자원이 응용서비스 공급에 사용되게 되어 연구·개발에 투입되는 자원이 줄어들게 되므로 첨단 응용서비스의 개발 및 확산이 지체되는 부정적 효과가 나타나 전자의 효과를 상쇄시킬 수도 있다. 본 연구에서는 최근의 내생적 성장이론(endogenous growth theoy)을 적용하여 이와 같은 초고속 응용서비스 확산 정책의 상반된 효과를 동태적 측면에서 분석하고 있다.
