T/CAB 0098-2021 Consumer product reliability improvement guide based on warranty data

Scope

Scope: This document provides guidance on improving the reliability of consumer products using warranty data, including planning improvement, operational improvement, evaluation improvement, and continuous improvement; Main technical content: This document is mainly used for consumer products with high quality requirements (mainly composed of electronic and mechanical components). Such consumer products are often affected by failures that may compromise consumer safety and quality, reduce customer satisfaction, or increase after-sales and warranty costs (for the specific classification of applicable consumer products, see Appendix A). Other types of consumer products can refer to this document for use. By using warranty data collected during use, the reliability of consumer products can be improved: by analyzing failure information from warranty data, through a system of failure reports, analysis, and corrective measures, and after comprehensively weighing targets such as costs and risks, appropriate reliability improvement measures can be proposed; after planning reliability improvement projects, feedback should be provided to product planning, design, and production, as well as after-sales departments, to achieve reliability improvement for batch products, modified products, and new products. At the same time, by carrying out reliability improvement management, reliability improvement projects can be tracked, and the effects of reliability improvement can be analyzed, thus achieving targeted and planned reliability improvement.
