Lean Six Sigma Black Belt: Improve (IASSC BOK) Exam with Complete Solutions

Lean Six Sigma Black Belt: Improve (IASSC BOK) Exam with Complete Solutions Design Of Experiments (DOE) a scientific method of planning and conducting an experiment that will yield the true cause and effect relationship between the X variables and the Y variables of interest Common types of DOEs Fractional factorials, full factorials, response surface methods (RSMs) 2k notation general notion used to designate a full factorial design, where k is the number of input variables/factors and 2 is in the number of "levels" that will be used for each factor. Ex. 3 factors 2^3 = 8 runs Full Factorial Experiment an experiment whose design consists of two or more factors, each with discrete possible values or "levels," and whose experimental units take on all possible combinations of these levels across all such factors
