Defect Prevention Based on 5 Dimensions of Defect Origin

This document presents a defect prevention framework for software development, highlighting five dimensions of defect origin, which include requirements, design, coding, testing, and timeline issues. It proposes preventive measures for identified defects at various stages and introduces a defect injection metric that assesses defects based on severity rather than just count, aiming to improve software process quality. The work aims to help practitioners choose effective defect avoidance measures and measure improvements in software development projects.
