  1. What is your approach when conducting a Supplier Process Audit?

  Answer:

  My process audit approach includes:

  1. Preparation

     • Review past NCs, PPM history, audit reports, and process flow.

  2. On-Site Study

     • Verify PFD, PFMEA, Control Plan alignment with actual practice.

     • Check machine capability, poka-yoke, traceability, maintenance records.

     • Validate operator training, WI, and material handling.

  3. Gap Identification

     • Note deviations, risks, and systemic issues.

  4. Audit Rating & NC Preparation

     • Categorize NCs as Major/Minor.

  5. Follow-up

     • Ensure CAPA within timeline with effectiveness verification.

  This ensures process capability, compliance, and defect prevention.

  2. How do you validate a PPAP submission from a supplier?

  Answer:

  PPAP validation includes:

  • Reviewing Part Submission Warrant (PSW)

  • Checking DFMEA, PFMEA, Control Plan

  • Verifying Process Capability (Cp/Cpk) reports

  • Checking Dimensional report, Material/Performance tests, and IMDS

  • Verifying Gauge R&R

  • Ensuring MSA, SPC, and packaging standards

  • Checking sample parts and verifying them against drawing

  Approval is given only if the submission meets OEM/IATF requirements and satisfies performance criteria.

  ---

  3. How do you handle supplier rejections and NC/CAPA closure?

  Answer:

  Steps:

  1. Immediate containment at supplier & incoming

  2. Perform Root Cause Analysis (5 Why, Fishbone, Why-Why)

  3. Define Corrective & Preventive Action

  4. Verify implementation & effectiveness

  5. Track PPM and ensure no repeat occurrence

  Timely escalation to management if supplier delays CAPA or repeated NCs occur.

  ---

  4. What actions do you take to reduce Supplier PPM?

  Answer:

  PPM reduction measures include:

  • Monthly supplier performance review

  • Strengthening incoming inspection standards

  • Implementing error-proofing at supplier

  • Ensuring SPC controls on critical parameters

  • Line revalidation and capability enhancement

  • Training suppliers on APQP & IATF requirements

  • Setting target-based improvement plans

  Focus is on preventive quality rather than reactive inspection.

  ---

  5. How do you evaluate a supplier’s Process Capability?

  Answer:

  I verify Cp/Cpk values for critical & significant characteristics:

  • Cp/Cpk ≥ 1.67 for critical characteristics

  • Cp/Cpk ≥ 1.33 for standard characteristics

  If below target:

  • Identify cause → tooling issues, measurement error, machine wear

  • Implement corrective action (tool change, setup optimization)

  • Re-evaluate after improvements

  Capability ensures stable and predictable output.

  ---

  6. How do you ensure supplier documentation meets APQP requirements?

  Answer:

  I check:

  • PFD, PFMEA & Control Plan linkage

  • Special characteristics marking

  • Gauge selection & MSA status

  • SPC charts for key processes

  • Trial run data and packaging validation

  • Run@Rate results

  APQP compliance ensures product readiness before SOP.

  ---

  7. What is your approach for handling repeated supplier quality issues?

  Answer:

  • Initiate Supplier Red Alert/Quality Hold

  • Conduct onsite deep-dive audit

  • Re-train supplier teams

  • Implement sorting + 100% inspection temporarily

  • Identify core systemic issues

  • Final closure only after capability studies and long-term fix

  Focus on sustained improvement, not temporary correction.

  ---

  8. What are common problems you face in machining or sheet metal supplier processes?

  Answer:

  Machining:

  • Tool wear, improper clamping

  • Incorrect cutting parameters

  • Variation in coolant

  • Dimension shift due to thermal conditions

  Sheet Metal:

  • Springback issues

  • Weld penetration inconsistency

  • Burrs due to die wear

  • Thickness variation in raw material

  SQA engineer must address these via tooling review, SPC setup, and revalidation.

  9. How do you manage Incoming Quality Control (IQC)?

  Answer:

  • Define AQL, sampling plan

  • Ensure instrument calibration

  • Verify material certificate, COA, COA

  • Maintain inspection records & traceability

  • Communicate rejections immediately to supplier

  • Implement skip-lot inspection for good-performing suppliers

  IQC ensures right material at right quality.

  10. Why is IATF 16949 important for Supplier Quality?

  Answer:

  Because it:

  • Maintains consistency in automotive quality systems

  • Ensures defect prevention

  • Focuses on risk-based thinking

  • Strengthens APQP, PPAP, SPC, MSA, and audit systems

  • Improves supplier capability and customer satisfaction

  It is the backbone of maintaining a zero-defect supply chain.
