Measure of the performance capability of a sampling plan, calculated from the discrimination ratio and valuation severity (according to the DGQ - German Society for Quality).
In the QM application component, it identifies a normal, reduced, or tightened inspection.
Sampling schemes can refer to sampling plans for inspection severity, or inspection severity and AQL (accepted quality level).
By varying the inspection severity, the probability of acceptance and the inspection effort can be flexibly adjusted to respond to different quality situations.
