• Operation numbers consistent with PFMEA, Control Plan, Operator Instructions
determined • Supplier and Delphi manufacturing site
notified of PPAP approval status
• Use A-8 Control Plan checklist in APQP manual to evaluate
152: 0P-PSAepP-99
Pre-Launch Control Plan
Early Production Containment requirements
– Additional controls included for proper duration or quantity
• Use A-7 Process FMEA checklist in APQP manual
1520: 0P-PSAepP-99
DFMEA
• Assess feasibility, risk, design intent issues • Confirm manufacturing process capability
< 10% acceptable 10-30% may be acceptable, evaluate total variation >30% unacceptable, measuring system needs
improvement
• Verify study performed correctly
– all design records and specification requirements are properly understood
– the process has the capability to produce product that meets requirements
• Ensure identification of inspection and rework
• Use A-6 Process Flow Chart checklist in APQP manual to evaluate

PFMEA
• Linkage with DFMEA, Process Flow, Control Plan, Operator Instructions, etc
– Design or process change
– Change in source of subcontracted materials or services
– transfer or rearrangement of tooling & equipment

tooling and meet
tooling, parts meet specs
specs, not all PPAP
requirements have been met
D parts do not meet specs
E parts do not meet specs
B parts from production and vehicles with class E
tooling and require
parts require retrofit to
rework to meet specs make them saleable
