You can use OptQuest to support process capability programs such as Six Sigma, Design for Six Sigma (DFSS), Lean principles, and similar quality initiatives. To do this, activate the Crystal Ball process capability features by selecting Calculate Capability Metrics on the Statistics tab of the Run Preferences dialog. Once you do that, define a lower specification limit (LSL), upper specification limit (USL), or both for a forecast in the Define Forecast dialog. (You can also define an optional value target.)
Once you have defined at least one of the specification limits, you can optimize capability metrics for that forecast. The process capability metrics are displayed with other forecast statistics in the OptQuest Objectives panel. When you copy the values back to the model, the optimized values, relevant forecast charts, and the capability metrics table are displayed in the workbook. See the Oracle Crystal Ball User's Guide for more information.
