        From the Flow section of the action bar,
          click DOE
           and drop it on the
          process diagram.
        Double-click DOE
           .  The DOE Editor appears. 
         From the General tab's DOE Technique
          list, select Parameter Scan. 
      
         In the DOE Technique Options area, click Run
            baseline point if you want an additional point to run in which all factors
          are set to their baseline values.
         Including a baseline design point allows for the Parameter Scan technique to be
          used exactly as a simple finite differencing technique for sensitivity calculations (that
          is, the effective difference caused by each factor is independently varied by some small
          difference from a baseline design).
