AS9100 Clause 10.2: How to Pass the Verification of Effectiveness Audit

Missing verification of effectiveness is the single most common finding during AS9100 certification audits. Learn how to automate 30/60/90-day verification pulses.

Correction vs. Corrective Action: Why Auditors Reject CAPAs

One of the most frequent findings cited by AS9100 registrars is confusing Correction with Corrective Action:

**Correction**: Immediate containment and rework of the defective batch (treating the symptom).
**Corrective Action (Clause 10.2)**: Eliminating the root cause so the defect **cannot recur** in future production runs.

AS9100D Human Factors Requirement

AS9100D specifically added the requirement to evaluate human factors during root cause analysis. Simply stating *"Operator error — retrained operator"* is an immediate red flag to auditors.

A compliant investigation examines:

Was the ambient lighting adequate at the inspection station?
Did shift fatigue contribute to the error?
Was the drawing ballooning ambiguous or cluttered?
Did the CNC setup sheet lack a mandatory spindle warm-up procedure?

The Verification of Effectiveness Step (The #1 Audit Failure)

Clause 10.2(d) requires the organization to review the effectiveness of any corrective action taken.

A compliant verification record must answer:

1Time Horizon

Did we allow sufficient production lots (typically 30, 60, or 90 days or 3 subsequent production runs) to verify stability?

2Objective Evidence

Did we audit subsequent inspection logs, CMM dimensional reports, or scrap counters?

3Formal Signoff

Did the Quality Manager physically sign off on the effectiveness evidence prior to closing the CAPA?

Automating this verification pulse with scheduled notification alerts prevents open CAPAs from languishing until the week before your surveillance audit.
