Double-click the Six Sigma component icon 
.
The Six Sigma Component Editor appears.
From the General tab's Analysis Type list select Design of Experiments, and from the Technique list select Parameter Study.
In the Technique Options area, click Run baseline point if you want an additional point to execute in which all factors are set to their baseline values.
Including a baseline design point allows for the Parameter Study technique to be used exactly as a simple finite differencing technique for sensitivity calculations (i.e., the effective difference caused by each factor is independently varied by some small difference from a baseline design).
