Renaud and our senior engineer Paul Adams discuss the Taguchi method, also known as Robust Design. The Taguchi method is a tool used in engineering and manufacturing to improve product and process quality and reduce defects at an early stage. It is a statistical analysis approach used early in the product development process that reduces your costs and improves product quality and reliability, so is a popular way to develop products that are less risky to manufacture.
