fewer experiments, less time, less money

Question 3

what does more powerful mean

Answer 3

better understand of the effects of the main factors and interactions on the desired outcome

Question 4

Answer 5

DMAIC,

Define, measure, analyze, improve, control

Question 6

Describe “Define”

Answer 6

in listening to the voice of the customer, this phase helps us prioritize and improve those areas of greatest impact on the business

Answer 8

why is our process not meeting our goals? identify potential areas for improvement

take the solutions that you’ve thought about and then test them.

• this is where the design of experiments comes in

Question 10

define “control”
