Abstract: It is hard to directly measure the benefit of a software project’s quality cost. The paper supplies a solution to set up an organizational metrics baseline of quality cost. Meanwhile, the paper presents a quality cost analysis model based on defect metrics, which realizes the quantitative analysis of quality cost and its benefit, and provides objective evidences and guidelines for software quality assurance’s performance appraisal and quality investment decision-making.

Key words: Software metrics, Cost of software quality, Software defect
