PNSQC 2013 - Capers Jones
summary
Claims come from analysis of about 20,000 projects across 24 countries and show that the single best metric is defect removal efficiency — US average is 85% US average while best-in-class exceed 99%. Inspections plus static analysis plus testing typically yield inspections + static analysis + testing = ~99%. Other findings: defect potential is measured in defects per function point, severity‑2 bugs prove harder to locate than severity‑1, technical debt covers only ~17% of true quality cost, and pair programming cuts defects ~15% but doubles effort.
