In order to improve the quality of products, it is important to avoid contamination by defects in upstream processes, and to ensure quality in each process so that defective products are not allowed to flow into later processes. From this perspective, TEL is promoting front-loading and self-process assurance systems. In order to raise the degree of product quality at an early stage, we implement thorough risk detection and mitigation measures (FMEA*1) from the initial stages of product design in an effort to suppress the occurrence or outflow of defects. We also conduct thorough inspections in each process and verification using simulation in the self-process assurance system. Furthermore, these measures are implemented continuously and effectively in order to prevent similar problems, including using TEL 6 Step to discover the root cause of defects which occur at customer sites or internally.
