Corrective Action Effectiveness Verification

Service summary

An independent follow-up of corrective actions against agreed closure and effectiveness criteria. The review examines whether actions were implemented and whether available evidence supports the intended prevention of recurrence.

The service provides a documented conclusion on the actions assessed. Root cause analysis, action selection and implementation remain management responsibilities; a short follow-up period may limit conclusions about sustained effectiveness.

Key objectives

• Confirm implementation evidence
• Assess alignment with stated causes
• Evaluate recurrence and effectiveness data
• Identify incomplete or unsupported closures

Methodology

Selected actions are checked against the original findings, management’s response and subsequent operating evidence over an agreed review period.

• Agree findings, actions, effectiveness criteria and review period.
• Review original evidence, stated causes and approved action commitments.
• Confirm implementation through records, interviews or observation.
• Examine subsequent performance and recurrence information.
• Evaluate whether evidence supports closure and sustained effectiveness.
• Report verified status, limitations and any required further evidence.
