4.1 Governance and Operating Model

Supplier Quality Management (SQM) is notthe "Procurementtechnical withfirewall aseparating caliper."external Whilesupply Procurementchain focusesentropy onfrom your internal manufacturing stability. Unlike Procurement, which optimizes for cost and delivery (Commercial), SupplierSQM Qualityoptimizes focuses onfor riskRisk and capabilityCapability (Technical). TheThis missionchapter mandates the operational architecture required to extend process control beyond the factory walls, ensuring external partners function as reliable extensions of the SQM function is to extend the factory's quality firewall beyond our own four walls, ensuring that external partners operate with the same rigor as our internal lines.production This chapter defines the boundaries, authority, and operational rhythm of the Supplier Quality Engineer (SQE).line.

Mission and Boundaries

The SQESupplier isQuality theEngineer technical(SQE) conscienceoperates ofwith the supply chain. The role is governed by a strictabsolute separation of powers from Procurement. This separation is critical to prevent conflictsthe conflict of interest betweeninherent in prioritizing "gettingcheaper" the part cheap" andover "getting the part right.compliant."

  • The SQE Mission: To guarantee that no defective material entersIf the manufacturingissue streamis andTechnical that(Capability, supplierRisk, processesSpecification) are–> statistically capable of meeting specifications.
  • What SQE Ownsowns (Thethe "Red" Zone)decision.:
    • TechnicalMandate: Qualification:Exercise Vetoveto power over new suppliers based on audit results.
    • Material DispositionMandate:: The absolute authority to Block or Quarantine suspect material,material regardlessimmediately. ofThis authority overrides production urgency.
    • CorrectiveMandate: Action: Ownership ofOwn the SCAR (Supplier Corrective Action Request)Request cycle.(SCAR) cycle from initiation to validation.
  • WhatIf SQEthe Doesissue NOTis OwnCommercial (ThePrice, "Green"Terms, Zone)Logistics): –> Procurement owns the decision.

    • SelectionMandate:: We validate capability; Procurement selectsSelect the partner from the SQE-qualified list.
    • ExpeditingMandate:: ChasingExpedite late partsdeliveries.

Pro-Tip: Never allow "Commercial Leverage" to override a "Technical Veto." If a supplier is technically incapable, no price discount can compensate for the resulting line-down risk.

    The Operating Process MapLifecycle

    The SQM lifecycle of Supplier Quality is a closed-loop system,control system. Do not atreat these as linear seriesadministrative ofsteps; events.they are gates that must be cleared to proceed.

    1. Phase 1: Qualification (Pre-PO):

      • TriggerInput:: Procurement nominates a potential source.
      • ActionAction:: SQE performs aExecute Risk Assessment and On-Site Audit (VDA 6.3 / ISO 9001).
      • GateLogic:
        • :If Audit Score  Threshold –> Pass/Pass. Add to Qualified Vendor List (QVL).
        • If Audit Score < Threshold –> Fail. A failed audit places the supplier onAssign "Do Not Use" status in the ERP.status.

      Phase 2: Incoming Control (Active):

      • TriggerInput:: Material arrivalarrives at Dock.
      • ActionAction:: IQC (Incoming Quality Control) inspects per the SQE-defined Sampling Plan defined by the SQE.Plan.
      • OutputLogic::
        • If PassCompliant –> Release to StockStock.
        • If ORNon-Compliant –> Reject to MRB.

      Phase 3: Escapes & Reaction (Reactive):

      • TriggerInput:: Defect founddetected on the lineLine or in the field.Field.
      • ActionAction:: SQE initiatesInitiate Containment (24h) and issues aissue SCAR.
    2. Phase 4: Resolution & Monitoring (Sustaining):

      • TriggerInput:: SCARSupplier Response.submits CAPA.
      • ActionAction:: SQEVerify verifies the "Permanent Corrective Action"Action (PCA).
      • MetricMetric:: Update Supplier Scorecard update (Quality Component).Scorecard.
    3. Re-Validation (Loop):
      • Trigger: Major process change or annual schedule.
      • Action: Surveillance Audit to ensure the "Golden Process" has not degraded.
