Quality Engineering is the branch of engineering responsible for ensuring that products, processes, and systems meet technical, regulatory, and customer requirements. It operates transversally across the entire production chain — from development to post-sales — promoting reliability, traceability, and continuous improvement.
Quality Engineering ensures that what is designed, produced, and tested meets expected standards — and that failures are addressed at the source.
🧩 Quality Engineering Activities
| Area | Examples in industrial and testing context |
|---|---|
| Quality Planning | Requirements matrix, control plan, FMEA (FMEA) |
| Audit and Compliance | ISO certifications, traceability, process documentation |
| Quality Control | Inspections, measurement, tolerance limits, calibration |
| Quality in Testing | Coverage validation, approval criteria, FPY/CPK |
| Problem Solving | 8D, Ishikawa, 5 Whys, CAPA, failure dashboards |
| Continuous Improvement | Kaizen, PDCA, monitoring of KPIs |
📊 Commonly Used Indicators
- FPY (First Pass Yield)
- CPK / PPK (process capability)
- MTBF / MTTR
- OEE (equipment efficiency)
- Top Failures / Defect Pareto
- Cycle time and rework rate
