One may consider the recent history of the weathering discipline (the past 100 years or so) as an evolution of weathering experiments. This evolution trends from simpler, single variable experiments toward more stochastic and broader experimental approaches. All the different major types of weathering experiments represent important tools engineers can use for answering different types of questions regarding product development. In 1926 British statistician R.A. Fischer began applying fractional factorial approaches to agricultural experiments. In the 1960's Professor Genichi Taguchi included modified fractional factorial experiment designs for characterizing manufacturing processes in his quality engineering philosophy. Today, we present an application of modified Taguchi approaches to weathering experiments.
