**Quality Series (Sample Slides)**

Design of Experiments Quality Series (Sample Slides)

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.
