#OTD 2012 Genuchi Taguchi d (b 1 Jan 1924) 🇯🇵 founder of the Taguchi method for quality product improvement - reduction of process variation through robust design of experiments. His methods revolutionized manufacturing quality control practices & mindsets. 1/4 
2/ He collaborated throughout the 1950s with other notable statisticians such as CR Rao Fisher Shewart & was sponsored by Tukey at Princeton
3/ his methods differed from the conventional specifications based on tolerances alone but developed the concept of quality loss (rather than just quality)
4/ His method involves 3 steps: System design (operational specifications parts, materials, assembly); Parameter design ( deciding the most cost effective methods to control variation); Tolerance design (identification of key noise factors)
