SR&ED | SRED | SR ED
The first approach is referred to as the "One-Factor-At-A-Time" or "OFAT" approach and the other is a Statistically Designed Experiment or "DOE". The DOE is preferred for reasons that will be discussed. Unfortunately, the OFAT approach is most often used in industry. Within the definition of SRED is the idea that scientific research or experimental development is commensurate with a systematic investigation or search. Within the context of this article, I shall seek to demonstrate that a systematic investigation is superior to a search and show how a DOE is likened to a systematic investigation while the OFAT approach is nothing more than an inefficient search. The broad based acceptance, in industry, of DOEs as an approach to conducting a systematic investigation will accelerate technological advancement.
