A structured methodology for planning and conducting experiments to systematically study how input variables (factors) affect output responses. It operates through defined experimental designs — full factorial, fractional factorial, Latin square, and response surface — each specifying which factor-level combinations to test, which to alias, and how to estimate effects from the resulting data. The method persists through standardized design catalogs, analytical frameworks (ANOVA, effect estimation), and institutional practice in engineering and scientific research.

Definition
Why it is in scope
A systematic human-made methodology for planning, conducting, and analyzing controlled tests to study how multiple input factors influence output responses — structured through formal design types (factorial, fractional factorial, response surface, Taguchi) to extract causal relationships with minimum experimental effort.

Design of experiments as a formal discipline came from R.A. Fisher's work in statistics in the 1920s. Statistics existed first and fed into the creation of experimental design as a method.
