Process capability index

Probability and Statistics

The process capability index, also called the process capability ratio, is a statistical measure of how capable an engineering or manufacturing process is of producing output that falls within specified limits. It measures how much natural variation a process shows relative to its specification limits, allowing different processes to be compared by how well they are controlled, with higher index values indicating better performance. The concept of process capability is meaningful only for processes that are already in a state of statistical control.

Is Kind Of Object

Statistic, Concepts

Entity-backed identity for the object-kind enum value this mathematical object already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The object-kind fact itself stays on the object unchanged.
