Control Procedures

Control procedures are a convenience mechanism that you use to specify an overall testing and control scheme that is executed as process data is collected and analyzed. Each procedure is comprised of a list of control tests (listed in order of execution), and optionally, subgroup milestones indicating a progression for control limit calculations. You associate procedures with inspection characteristics to achieve the desired level of process control, feedback, and alarming.

PeopleSoft provides four predefined control procedures, each with a varying number of tests. You can use these predefined control procedures, modify them, or create a set of procedures:

Control Procedure ID #	Description	Control Tests
1	Level I	Specification limit violation.
1	Level I	Control limit violation (variance).
1	Level I	Control limit violation (mean).
2	Level II	Level I +.
2	Level II	Trend - 7 pts (mean).
2	Level II	Shift - 2 of 3 pts (mean).
2	Level II	Shift - 4 of 5 pts (mean).
2	Level II	Shift - 8 of 8 pts (mean).
3	Level III	Level II +.
3	Level III	Trend - 7 pts (variance).
3	Level III	Shift - 2 of 3 pts (variance).
3	Level III	Shift - 4 of 5 pts (variance).
3	Level III	Shift - 8 of 8 pts (variance).
4	Level IV	Level III +.
4	Level IV	Mixture - 8 pts (mean).
4	Level IV	Systematic variable - 14 pts (mean).
4	Level IV	Stratification - 15 pts (mean).
4	Level IV	Mixture - 8 pts (variance).
4	Level IV	Systematic variable - 14 pts (variance).
4	Level IV	Stratification - 15 pts (variance).
