Zero-Defect Manufacturing (ZDM) is a quality assurance strategy that focuses on eliminating defects from the production process. It involves establishing process controls, identifying and addressing potential problem areas, and ensuring that every product is produced to the highest possible standard. The goal of ZDM is to reduce production costs by preventing defects in the first place, rather than detecting and correcting them after the fact. The result is a higher quality product and a more efficient production process.
