2. Outline What is Design of Experiments? Method
Step 1: Model Variables
Step 2: Set Variable Targets
Step 3: Experimental Plan
Step 4: Testing
Step 4: Analysis
Effects, Replicates & Interactions

3. DOE Goal Overall goal: Our approach:
To model a performance parameter (i.e., a physical phenomenon) as a function of design variables (i.e., things we can control about the design)
Our approach:
Follow the DOE methodology

4. Step 5: Analysis Determine ß coefficients
Regression analysis may be used (spreadsheets)
ßs can be defined in terms of the effect a variable xi has on the perf. parameter

5. Using the Effects From a response diagram point of view: Important DV
Plot values of y vs. xi(-) and xi(+)
Important DV
DV has no effect on perf.
