  • Are open corrective actions tracked and reviewed at regular management review meetings?
  • Is there evidence that the customer has been notified of corrective action completion and closure?

Complaint Data Analysis and Trend Monitoring

Assess whether complaint data is analyzed for trends and used to drive systemic improvements.

  • Is complaint data analyzed regularly for trends, Pareto analysis, and recurring failure modes?
  • How many customer complaints were received in the current review period?
  • What is the average complaint resolution time in days for the current review period?
  • Are complaint KPIs reported to top management as part of the management review process?
  • Is complaint data used to identify systemic issues that are incorporated into the risk register or FMEA updates?

Customer Communication and Satisfaction Monitoring
