Abstract
In order to achieve QCD (quality, cost, and delivery) targets of a software product development project, it is important to measure process of the software product and process, to evaluate the software project quantitatively based on quality standards, and to improve it continuously. This paper shows how to evaluate the project quantitatively by using product and process quality indices based on the organizational activities to improve the defect removal efficiency and to minimize delivered defects. Then, we discuss the relationship between the quality indices and QCD results by analyzing the data of several software projects which are evaluated quantitatively. Moreover, we show the improvement effect for application of defect removal efficiency.
