Quality Capability Values

From the Statistics > Process menu, you can calculate quality capability values:

Calculating the Quality Capability Cp Value
Calculating the Quality Capability Cpk Value

Quality Capability Statistics (QCS), also called Process Capability Statistics (PCS), covers the calculation of values according to DIN 55319-3:2002 Method M4. A distinction is made between variance-based (C_p) and variance location-based (C_pk) values.

Note: QCS is typically used in conjunction with traffic light plots, with red values for c_pk < 1.0 and green values for c_pk > 1.33.
