Control Rule Violations

Control rules are used to identify and reduce the non-random variability within a process. You can configure one or more control rules for a specification that is linked to one or more characteristics, which are applied if the severity for the characteristic is Non-Key, Key, or Critical.

Control rules are validated when

• An individual reading for a characteristic is recorded in the MES database.

• Rule violations, if any, are reported as a warning message to the client.

The control rules are evaluated against a characteristic that is linked to a most recent sample.

Control rules are not evaluated or validated against a characteristic that is linked to a sample whose sample time is in the past and is not the most recent sample for the characteristic.
