Robust Design is a methodology aimed at improving product quality and performance by minimizing the effects of variability. It focuses on creating products that perform consistently under different conditions, ensuring reliability and customer satisfaction. This approach is often used in engineering and manufacturing to enhance the durability and functionality of products. The concept was popularized by Genichi Taguchi, a Japanese engineer and statistician, who developed techniques to optimize design processes. By incorporating robust design principles, companies can reduce costs associated with defects and failures, leading to more efficient production and better overall outcomes for consumers.
