FAQ : We answer your most asked questions
What is preventive quality control?
Preventive quality control (PQC) is a proactive system that builds quality into the manufacturing process to avoid defects before they occur—through process design, training, standard work, and risk-based controls—rather than finding defects at the end with inspections. In short: prevention > detection.
How is preventive quality control different from traditional QC or QA?
- QA (assurance): designs and maintains processes to prevent defects (proactive).
- QC (control): detects defects in outputs (reactive).
- PQC operationalizes the preventive side inside factories (training, control plans, SPC, mistake-proofing) so fewer issues reach final QC. You still keep QC as a safety net, but rely on it less over time.
What does a preventive QC program include for suppliers in Asia?
Typical scope: on-site process audits, factory training, a tailored QC plan, weekly visits, KPI tracking, CAPA, supplier scoring, and a step-down plan to reduce third-party inspections as the process stabilizes. This is precisely how Amazing Quality Control structures its service (onboarding → foundations → stabilization → ownership) across China and Vietnam.
What KPIs should we track to prove prevention works?
Start with: defect rate (ppm/%), first-pass yield, top 3 recurring defect types, CAPA closure lead time, process capability (Cp/Cpk) on critical dimensions, on-time delivery linked to quality holds, and audit conformance. Trend them weekly during stabilization; monthly once the line is stable. This mirrors the KPI/scorecard approach used in the AQC 6-month program.
How long does it take to see measurable results?
A realistic cadence: Weeks 1–2 onboarding & plan; Months 1–2 foundations with weekly visits and early defect reduction; Months 3–4 process stabilization via deeper CAPA; Months 5–6 ownership/self-inspection and a decision on reducing external inspections. Many importers see fewer disputes and lower total quality costs by Month 3–4.
What’s the difference between corrective and preventive actions (CAPA) in PQC?
- Corrective: fixes a found non-conformity and stops recurrence.
- Preventive: anticipates risks and stops occurrence in the first place (e.g., mistake-proofing jigs, upgraded SOPs, poka-yoke). A mature PQC program runs both, but weights resources to prevention.
Does preventive QC replace pre-shipment inspections?
No. It reduces dependency on end-of-line checks. You’ll keep PSI for high-risk items or new SKUs, but the goal is to shift quality upstream, so PSI becomes a confirmation rather than your only control. AQC’s model explicitly plans a step-down in third-party inspections after the supplier demonstrates consistent KPIs and self-inspection discipline.
How do you roll out preventive QC with factories in China/Vietnam/Thailand/India?
- Define critical-to-quality (CTQ) specs and risks.
- Audit the current process on-site.
- Build a control plan (incoming, in-process, final), sampling aligned with ISO 2859/ANSI ASQ Z1.4 where detection remains needed.
- Train operators & supervisors; deploy checklists and go/no-go gauges.
- Run weekly Gemba + layered process audits; track KPIs; close CAPA.
- Quarterly reviews and supplier scoring; expand to other lines/sites. (AQC operates this cadence across China and Vietnam.)
What’s the business case—does prevention actually cost less?
Detection-heavy models (100% end checks, repeated rework, shipment holds) are expensive and imperfect; prevention reduces scrap/rework, chargebacks, returns, and re-inspection fees. Lean/Six Sigma literature and industry practice emphasize prevention as the most economical path to quality.
Which standards or frameworks support preventive quality control?
- ISO 9001 for process-based QMS and continual improvement (QA foundation).
- ISO 2859 / ANSI ASQ Z1.4 for acceptance sampling when detection is still needed.
- Quality Risk Management (QRM) to prioritize controls by severity/likelihood.
- CAPA methodology for sustainable fixes. Use these together to design a robust PQC system.
