Control plan revision not propagated to operator work instructions.
You revised the FMEA for the new bracket assembly, but operators are still working from the old control plan torque spec.
"ISO 9001 §8.5.1 requires planned and controlled implementation of production and service provision, including the availability of documented information that defines the characteristics of the product and the activities to be performed, and the implementation of monitoring and measurement activities at appropriate stages."
FMEA-2025-014 Rev 04 (released 2026-01-15) updated the torque spec for the upper-bracket fastener from 12 Nm ±2 to 10 Nm ±1 due to pull-test failures. Control plan CP-ASSM-007 Rev 03 was updated 2026-01-22. But operator work instructions WI-ASSM-007-OPS Rev 03 still reference 12 Nm ±2 — most recent revision check shows 2025-09-12, predating the FMEA change. Three lots produced under the old WI between Jan 22 and Feb 4, 2026.
