摘要：This paper reports the results of an empirical study, where some hypotheses about the relationship between software quality, expressed in terms of defect density, and cost estimation drivers (cost factors) are assessed. The study is performed using three cost factors, these are: work effort, project size, measured in terms of function points, and average assigned work per team member. The study is performed using the ISBSG repository data set release 12. ISBSG dataset which contains 6006 completed project. For statistical analyses, Regression Analysis and stepwise Analysis of Variance (ANOVA) are used. Our results show that there is a significant negative impact of the project size and work effort on the defect density. On the other hand, the average assigned work per team member has a significant positive impact on defect density. These results suggest that while assigning resources to a project, these quality factors should be considered in order to decrease the defect density, and thus, the maintenance cost of the product.
