G. Taguchi

Genichi Taguchi was a Japanese engineer and statistician known for developing methods to improve manufacturing quality. His approach focuses on designing products and processes that are robust, meaning they perform well despite variations. Taguchi's key ideas include using special experiments called "design of experiments" to identify the best settings, and creating "loss functions" to measure how much a product’s quality deviates from ideal standards. His methods help companies reduce defects, improve efficiency, and deliver consistent, high-quality products, ultimately saving costs and enhancing customer satisfaction.
