 Quality Level (QM-QC-AQC-LEV)

Definition

The quality level is a data record that the system automatically updates at the time of dynamic modification (at lot creation or when the usage decision is made), by checking the conditions for an inspection stage change and, if necessary, storing a new inspection stage for the next inspection.

Use

The information in the quality level determines which inspection stage will be used for the sample determination of the next inspection lot.

The system updates the fields in the quality level differently during dynamic modification. This depends on whether dynamic modification occurs at lot creation or when the usage decision is made. You define which of these times will apply in the dynamic modification rule .

Structure

The following information (among other data) is contained in the quality level at the header or characteristic level:

  • The number of inspections that have occurred since the last stage change.

  • The number of inspections that were unsuccessful.

These counters are updated accordingly each time the quality level is updated. The system uses these counters to determine when an inspection stage change should occur. The conditions for a stage change are defined in the dynamic modification rule.
