1. What is the ultimate goal of six sigma approach to the product quality?
a. 
Influence suppliers to increase quality of their products 

b. 
Reduce variability of the process so the scrap rate is at levels as low as 3.4 per million 

c. 
Implement Taguchi method of quality control 

d. 
Decrease the probability of failure to 3.4% 

e. 
Develop standardized procedures for all processes in a company (DMAIC, DMADV…) 
2. What is the most important advantage of a “real” statistical design of experiments over “engineering,” or classic, DOE?
a. 
Principles of statistical DOE can be applied to any discipline, not only engineering 

b. 
Engineering DOE requires highly specialized expertize 

c. 
Statistical DOE requires smaller sample size and/or smaller number of experimental runs 

d. 
Statistical DOE requires less calculation 

e. 
Statistical DOE can find interactions between influencing factors, while “engineering” DOE usually cannot 
3. What is the contemporary/lean/Taguchi’s approach to quality?
a. 
All three above: a), b), c) 

b. 
There is no loss as long as the process stays within the control limits 

c. 
Any deviation from the exact target value induces some loss 

d. 
None listed here 

e. 
There is no loss as long as the process stays within the specified limits
