Lean QA: Much more cost-effective Quality Assurance methods, than testing
summary
Claim: quality assurance is much broader and cheaper than relying on testing alone Evidence: regression testing historically finds 10–30% of bugs and integration testing about 25–40%, while inspections and static review move detection earlier and cut fix cost roughly tenfold Capers Jones shows even the best serial testing and inspection tops out near 95% coverage, so combine inspections with defect prevention to raise yield Practical result offered: Intel trains 15,000 engineers and cuts a 312‑defect requirements document to 10 (≈40× reduction)
