Quality Control
Quality Wall
A quality wall is your last defense before parts ship to your customer. ISS sets up project, prelaunch, and series quality walls that match your launch phase and risk profile. Our teams build the inspection routine, track PPM in real time, and feed defect analysis back to your engineering team for permanent corrective action.
What we do
Quality wall scope
Project quality wall setup
Pre-production parts validation during PPAP and pre-series phases.
Prelaunch quality wall
Ramp-up support during the 4M change window when defect risk is highest.
Series quality wall
Ongoing 100% inspection on critical parts or after a quality crisis.
Effective control plan elaboration
We design the inspection sequence, sample sizes, and decision criteria.
PPM process and quality wall tracking
Daily, weekly, and monthly PPM reporting with trend analysis.
Defect analysis participation
Our team joins your QRQC sessions with structured defect data.
Daily reporting
Standardized reports delivered before the next shift, with categorized defect rates and corrective recommendations.
When this applies
Trigger situations
- Customer-imposed quality wall after a major defect escape
- New product launch with zero-PPM commitment
- Process change requiring temporary 100% inspection
- High-risk or safety-critical part requiring permanent monitoring
- Pre-shipment containment during a quality crisis
How we deliver
Methodology
We deploy in 24 to 48 hours when the situation is critical. Our standard quality wall combines a digital scanning station, a defect classification system, and a daily reporting cadence aligned with your quality team. Every defect is photographed, classified, and traced. When trends emerge, we escalate to your QRQC immediately. The goal is always the same - return your process to autonomous quality as fast as possible.
