Overview of the Process Screening Platform
The Process Screening platform facilitates the task of assessing data from a large number of processes for stability and capability. The results are largely based on control chart calculations to determine when a process is out of control. The Process Screening platform enables you to do the following:
•
Specify a constant subgroup size or use a variable containing subgroup identifiers for control chart calculations using subgroups.
•
Use grouping variables. For each combination of values of the group variables, an analysis is provided for each process variable.
•
Use medians to make your centerline and sigma calculations robust to outliers.
•
Obtain information about the location of large shifts in the mean of your processes.
You can customize the Summary report to show specific control chart tests, including tests for changes in process mean and spread. The report also provides capability information when you supply specification limits. The Process Performance Graph gives you a visual representation of the performance of your processes in terms of stability and capability. The Shift Graph shows locations of upshifts and downshifts.
Tip: For information about adding specification limits, see Spec Limits in the Using JMP book.
Process Screening makes it easy to select specific processes for further analysis. The platform provides small run charts for these processes - the size of the plots makes it easy for you to view a substantial number at a time. You can also link to Control Chart Builder and the Process Capability platform for analyses of select processes.
You can save data tables containing results in various forms, either for your entire set of processes or only for select processes.
