Use the Statistics tab of the Run Preferences dialog to activate the process capability features. After they are activated, you can:
Add upper and lower specification limits and target values to forecast definitions (Setting Specification Limits and Targets).
Display the Capability Metrics view in the forecast window, in addition to the basic Frequency, Cumulative Frequency, Reverse Cumulative Frequency, Statistics, and Percentiles views (Viewing Capability Metrics).
Use Crystal Ball’s Split View feature to display the Capability Metrics view beside one of the forecast chart views (Viewing Forecast Charts and Capability Metrics Together). This is the default.
View marker lines for specification limits and the target value on forecast charts (Viewing LSL, USL, and Target Marker Lines).
Extract capability metrics to a worksheet using Analyze, then Extract Data or the Auto Extract forecast preferences (Extracting Capability Metrics).
Include capability metrics in reports (Including Capability Metrics in Reports).
Include several capability metrics in OptQuest, if you have a license for it, and specify them as objectives or requirements.
Access capability metrics in the Crystal Ball Developer Kit using these calls: CB.GetFore, CB.DefineForeND, CB.SetView, CB.GetForeStat, CB.RunPrefsND, CB.GetRunPrefs, CB.CreateRptND, and CB.ExtractDataND (see the Crystal Ball Developer Kit User's Guide for more information)
Several of these calls have equivalent spreadsheet functions and can be used in worksheet cells instead of VBA macros.
The following sections summarize process capability initiatives for quality improvement and describe how Crystal Ball's process capability features support those initiatives:
