Which is a benefit of DOE in helping to add definitiveness in design decisionmaking?

a. Engineers feel more motivated because proof is not needed for changes.

b. Tooling costs are reduced since dies must be designed and built only once.

c. Carefully planned input patterns do not support authoritative proof.

d. Documentation becomes more difficult since there is no moving target.

e. Quality likely improves because randomization does not generate rigorous proof.
