Quality Control (QC) and Reliability Engineering are critical pillars of modern industries. They ensure that products, systems, and processes meet high standards of performance, safety, and durability. While quality control focuses on detecting and correcting issues during production, reliability engineering ensures long-term product performance and dependability. Together, they drive customer satisfaction, cost reduction, and brand trust.
