8.7Verification vs Validation in Different Methodologies
| Methodology | Verification Emphasis | Validation Emphasis |
|---|---|---|
| Waterfall | Heavy (testing phase against detailed specs) | Late (UAT at the end, expensive to change) |
| Agile | Continuous (automated tests, CI/CD) | Frequent (sprint demos, user feedback each iteration) |
| DevOps | Automated (pipeline gates, quality checks) | Continuous (feature flags, canary releases, monitoring) |
| Lean/Startup | Minimal (just enough to avoid breaking things) | Primary focus (validated learning, MVP testing) |
