QSB vs BIQS
Understanding the Two GM Supplier Tiers
GM operates a two-tier supplier recognition system. Every GM supplier is expected to meet QSB. BIQS is the advanced tier that drives preferential sourcing treatment.
Baseline requirement
QSB — Quality System Basics
GM's baseline supplier quality standard. Every GM supplier is expected to meet all 11 QSB elements. QSB non-compliance is treated as a systemic quality risk — triggering escalation, increased oversight, and potential sourcing impact. Meeting QSB is the entry requirement, not the goal.
Advanced recognition
BIQS — Becoming an Ideal GM Supplier
GM's advanced supplier recognition program. BIQS suppliers have embedded a mature, proactive CI culture — with documented improvement projects, sustained results, and evidence the CI program is a strategic priority. BIQS suppliers receive preferential new program sourcing consideration and reduced GM oversight burden.
All 11 Elements
The GM QSB Elements — Mapped to PlantPilot AI
Every QSB element has a direct PlantPilot AI capability that addresses it. Here's the complete mapping — with audit priority for each.

| # | QSB Element | What Auditors Check | PlantPilot AI | Priority |
|---|---|---|---|---|
| 01 | Containment | Speed and structure of response when a defect escapes — documented SOP, not improvised | 8D Report Generator | Critical |
| 02 | Problem Solving | Data-verified root cause methodology — Fishbone or 5-Why with evidence, not opinion | RCA Module (Fishbone + 5-Why) | Critical |
| 03 | Control Plans | Current control plans reflecting actual process — updated after changes, linked to PFMEA | Document Generator · Control Plan | Critical |
| 04 | Standardised Work | SOPs at point of use, current revision, operator sign-off records, deviation process defined | SOP Library + Standard Work Builder | Critical |
| 05 | Error Proofing | Poka-yoke devices documented in PFMEA, verified functional, response process defined | PFMEA + Corrective Action Tracker | High |
| 06 | Appearance Approval | Valid AAR on file for appearance-significant parts, reviewed after process changes | Document Generator · AAR | Moderate |
| 07 | PFMEA | Living PFMEA — updated after every failure mode discovery, revised after process changes | Document Generator + RCA Integration | Critical |
| 08 | Layered Process Audits | LPA schedule maintained, all leadership tiers completing audits, findings tracked to close | 5S Audit Tool + Action Tracker | High |
| 09 | Mistake Proofing Verification | Daily/shift verification of poka-yoke functionality — logged consistently, no gaps | Corrective Action Tracker · Daily Log | High |
| 10 | Run at Rate | OEE at or above target — documented with 90-day trend data, not spot measurements | OEE KPI Dashboard · Real-Time | Critical |
| 11 | Continuous Improvement | Active DMAIC portfolio with documented ROI, linked to GM-relevant KPIs | DMAIC Project Manager + Kaizen | Critical |
The BIQS Path
From QSB Compliance to BIQS Recognition — With PlantPilot AI
The difference between a QSB-compliant plant and a BIQS-recognised plant is almost never operational capability. It's CI infrastructure. A CI Manager spending two days a week manually generating documentation, chasing LPA records, and updating PFMEAs by hand is a CI Manager who isn't driving the improvement portfolio GM is looking for. PlantPilot AI automates the documentation — so your CI team's full capacity goes to the work that earns BIQS recognition: sustained, measured, documented improvement across all 11 elements.
GM QSB Audit Readiness Checklist
Click each item to track your readiness before your next GM audit.
- ✓Containment response SOP documented — practiced response time under 24 hoursGM expects a repeatable, documented containment process — not individual heroics each time a defect escapes.
- ✓Last 5 quality escapes closed with data-verified root cause (not assumed)GM auditors pull your last 5 corrective actions and look for evidence root cause was confirmed with data.
- ✓All SOPs at point of use, current revision, operator sign-off currentSOPs on a shared drive don't satisfy QSB Element 4. GM expects laminated, current SOPs physically at the workstation.
- ✓LPA schedule active — all leadership tiers completing audits on scheduleGM specifically checks Plant Manager level LPA participation. Delegation defeats the purpose of layered audits.
- ✓OEE at or above 75% — 90-day trend documentation by line, not just plant average85% is the world-class benchmark GM references. Trend matters as much as the current number.
- ✓Active DMAIC project tied to a GM-relevant KPI (PPM, OEE, scrap, delivery)For QSB Element 11, GM wants to see an active CI project tied to a metric that matters to GM — not internal housekeeping.
- ✓All poka-yoke devices verified functional — daily verification log current with no gapsGM auditors test poka-yoke devices on the spot. A verification log with any gap — even one day — is a finding.
- ✓PFMEA reviewed and updated after every quality escape in the last 12 monthsGM auditors cross-reference your quality event log against your PFMEA revision history. The dates must align.
