What Is An ISO 20000 Customer Complaint Report Template?

An ISO 20000 Customer Complaint Report Template is a structured document used to record, investigate, resolve, and report customer complaints related to IT services and service delivery. It helps service providers document complaint details, customer information, affected services, impact, resolution actions, escalation, and improvement measures in a consistent format. Customer complaints can provide valuable information about service performance, customer expectations, service gaps, and opportunities for continual service improvement within an ISO/IEC 20000-1 Service Management System (SMS).
