Question

489: A six sigma green belt has run a 25-2 fractional factorial design. Only 2 of the 5 factors remained important after the factorial analysis. Escalation of this DOE to an optimization model will be best accomplished by:

A. Performing a new full factorial of the 2 factors

B. Performing a response surface experiment

C. Decreasing the degrees of freedom of the original DOE

D. Adding an additional factor level

Answer 1

Solution:

Option B

The correct option is option B because the best way to accomplish the optimization model from the escalation of DOE will be to perform a response surface experiment. This is the logical step that is to be taken in a DOE and hence the correct choice is option B.
