Failure modes Noises lead to failure modes(Fm) One set of noise values leads to fm Opposite set of noise values leads to FM Simple problem solving chases the problem from Fm, to Fm, and back again but does not avoid both fms with the same set of design values-endless cycles of build/test/fIx(B/T/F) C Don Clausing 1998 6.881

Ideal response Want Ideal Response to Signal -usuall straight-line function Actual response is determined by values of control factors and noise factors If noise factors are suppressed early, the en difficult problems only appear late Introduce noises early C Don Clausing 1998
