Problem solving (IATF only)
Plain-language summary
One documented problem-solving process (with defined approaches for different issue types and scales) covering containment through verified effectiveness and systemic prevention — using the customer's format where they prescribe one.
What the clause is really asking
The process must include: defined approaches per problem type/scale, containment and interim actions, root cause analysis (methodology, analysis, results), systemic corrective action implementation, verification of effectiveness, and review/update of affected documented information (PFMEA, control plan). Customer-prescribed formats/systems are used where required.
What auditors look for
Auditors sample 8Ds/A3s against the full chain — the two classic gaps being verification of effectiveness (D7 hollow or missing) and the document-update step (PFMEA/control plan untouched after the fix). Customer-format compliance gets checked against CSRs.
Typical evidence
Documented problem-solving procedure; completed 8D/A3 reports; FMEA/control plan revision links from problems; customer portal submissions where required.
How to comply — recommendations
Adopt 8D as the single house method with a one-page version for small problems. Hard-gate two steps in the form: 'effectiveness verified by/on' and 'FMEA & control plan updated? rev:' — those two fields fix the findings auditors most often write.
Common nonconformities
Root cause stopping at 'operator error'; D7/effectiveness never done; FMEA and control plan not updated after problems; customer-required format ignored.
