Corrective action and preventive action may be initiated through any of four methods: (Internal) Corrective Action Request, Supplier Corrective Action Request, Complaint Reports, and Internal Audits. Inherent in each system are provisions for follow-up through increasing levels of management to ensure effectiveness. Control of the corrective action and preventive action system is the responsibility of Quality Assurance in accordance with the Corrective and Preventive Action SOP - 90C0010. The quality system is designed to minimize the need for corrective actions by preventing non-conformances from occurring in the first place. Internal Corrective Action is initiated when an internal audit, review of quality records (including trend analysis), or observation identifies the need for investigation and corrective action. Each ZOLL employee has authority to, and responsibility for initiating a Corrective Action Request through QA when a quality problem, or potential quality problem is identified. Supplier Corrective Action is initiated when a nonconformance or observation of a quality problem is determined to be the responsibility of a supplier or contractor. Complaint Report Forms are initiated in accordance with the Complaint Handling SOP - 90E0012 when a returned product or customer complaint is received, or when a distributed device fails to meet specifications. Audit Reports are initiated when a quality audit identifies deficiencies or areas for improvement. When corrective action involves a product recall or the issuance of an Advisory Notice, these actions shall be performed in accordance with the Device Recall Procedure - 90C0023. 17.2 Complaint Files All complaints and malfunctions of a distributed device are documented via the Receipt and Evaluation of Product Complaints SOP - 90E0012. The Complaint Review Unit (CRU) of ZOLL is responsible for reviewing, evaluating, and investigating complaints and maintaining complaint files. The CRU ensures that complaints are processed in a uniform and timely manner.
