From simulation operation management sinulation quality analytics by barbara b flynnChallenge $3(3$ points in total$)$:

a$.$ What were your process capability indices for each of the four companies? $(1$point, $0\mathrm{.}25$ points for each$)$

b$.$ How did you know which process capability index formulas to use?

c$.$ How did you determine which process mean and standard deviation to use?

d$.$ What does it mean when the control limits fall within the specification limits$?$ Is this a good situation or bad situation?

e$.$ Where do specification limits come from? Can you provide some examples?

f$.$ What does six sigma mean, in the context of control limits and specification limits$?$

Challenge $4(3$ points in total$)$:

a$.$ What was the best total cost of quality that you achieved? How did you achieve it$?$

b$.$ How to prevention costs interact with internal failure costs and external failure costs?

c$.$ How do appraisal costs interact with internal failure costs and external failure costs?

d$.$ How do prevention costs interact with appraisal costs?

e$.$ What happened to the total cost of quality as you increased your investment in prevention and appraisal?

f$.$ What were the largest and smallest component of the total cost of quality for your BEST strategy?

g$.$ As you increased your investments in prevention, were you able to do less sampling and inspection $($reduce sample size and$/$or frequency$)?$ Why?
