Their secret is the Taguchi Method, which is a technique for designing experiments that converge on an ideal product solution.
"I taught over 300 courses for industry where we designed cars and electronic devices, but it wasn't until one day I took over my wife's kitchen and used Taguchi to perfect my recipe for vanilla wafer cookies that I realized how broadly it could be applied," Kowalick recalls. "It took 16 batches, but by the end of the afternoon I had those wafers dialed in."
It is great to see the application of Designed Experiments increasing. I am reminded of an article by my father, William G. Hunter, from 1975: 101 Ways to Design an Experiment, or Some Ideas About Teaching Design of Experiments. Examples of the topics of the designed experiments his students performed:
- taste of stewed chicken
- toys child chose to sleep with
- quality of ground malt for brewing beer
- distance football was kicked
- absorption characteristics of activated carbon used with municipal waste water
