Complaint analysis separates the immediate customer remedy from the process change needed to prevent recurrence. Both matter: resolving one case does not show that the underlying failure has been removed.
Record the complaint, affected product or service, timeline and available evidence. Group similar cases and examine the relevant handoffs. Avoid deciding on a cause before checking whether the records support it.
Assign corrective actions and review their effect on future incidents. Monitor both recurrence and the quality of the response to customers. Update instructions or controls when the evidence shows a repeatable process problem.
