Prediction of defect distribution based on project characteristics for proactive project management

As software has been pervasive and various software projects have been executed since the 1970's, software project management has played a significant role in software industry. There are three major factors in project management; schedule, effort and quality. Especially, to represent quality of products, there are various possible quality characteristics of software, but in practice, frequently, quality management revolves around defects, and delivered defect density has become the current de facto industry standard. The researches related to software quality have been focused on modeling residual defects in software in order to estimate software reliability.
