What is Design of Experiments?
And why is DOE important? 1d 2d
Think about it R1 R2 x1 x2 x3 x4 x5 XN . 3d

2. Discussion: Edison & Einstein
DOE
Edison: I didn’t fail 10,000 times, I learned 10,000 ways that won’t work.
Einstein: I could have worked out the physics in a week.
Edison: But would you prove it’s the optimum solution?
Einstein: Yes, I see the value of Design of Experiments!

3. Terminology of the DOE Science
DOE: statistical modeling of test plans
Factors: measurables affecting response
Response(s): the desired measurable(s)
JMP/DOE: interactive software platforms
Evaluation: statistical goodness measure !
Iteration: repeating the designs and tests (on products, or enterprise, or services!)

5. Envision, Plan, Do, Check, Act
PLAN (design) the experiment;
DO the experiment by performing the steps;
CHECK the results by testing the information;
and ACT on the decisions based on those results.

Check Do

W. Edwards Deming:
Dr William Edwards Deming
Plan
was an American statistician,
professor, author, lecturer and consultant.
He is perhaps best known for the cycle of
Envision
Envision >> Plan >> Do >> Check >> Act! {[(repeat)]}

7. Full-Factorial The basis of the science is to choose ranges for the
n factors and assign a top value and low value for each
factor. The factors can be varied and starting optimum
results calculated. The icon picture represents an
n-dimensional cube and if a middle dot is shown,
it means a middle value can also be used.
Math example: 5! = 5x4x3x2x1 = 120 cases
“Five factorial has 120 combinations!”
(If too costly, we can try to do better.)

Custom Design
The JMP Custom Design allows you to tailor your plan
of experiments to meet specific requirements. Custom
Design is often the first choice that one choses from the
available design options. This is most advisable!
Design professionals begin with Custom Design.

9. {RSM} (response surface method)
Response Surface Design
At some point, you want to do some auxiliary statistical
graphics, visualization, and optimization exploration.
You can do this with JMP to look for local and global
maximum or minimum points on the factor surface.
Visually, see maximum peaks (or minimums) on plotted
surfaces. Assess if you are at localized peaks or valleys,
or are they are the global solution you seek.

11. Sonic, America’s Drive-In
“We are hiring, and growing!”
What determines good employees?
Let’s consider the hiring process. Who should be hired based on initial information, and augmented in the future by performance reviews and other measurable factors?
First Iteration:
Use JMP/DOE Custom Design with a response factor of service times performance:
I.e. for the last year of hiring, RATING = (weeks served) times (performance rating).
Begin in Oklahoma City, and then in California. Propose the tests to the Sonic CEO.
Future Iterations:
Use JMP/DOE Augment Design to add additional factors, to be determined, and
additional new-hire data as it becomes available expanding to additional states.

13. Sonic, America’s Drive-In
“We are hiring, and growing!”
What determines good employees?
The design of 12 test
runs is a lot less than
the 54 from before.
These 12 runs will
compete very well
with the 54 runs !
They will be sufficient
to begin iteration after
fine tuning your plans
and statistical analysis.
These 12 test cases
constitute the new
design 

DOE models.

14. What we have covered . . . Steps: Think, Design, Test, Analyze, Act!
Improvement involves iterations (repeat)
Custom Design starts your path . . .
Consider specialized design platforms
If possible, use full-factorial design
As need, try other JMP/DOE platforms.

15. Employ the entire design theory
Involve key people
Determine the factors
Start with Custom Design
Analyze every step of the way
Continual improvement is the goal
