Process Capability and Performance Calculator
Calculate Cp, Cpk, Pp, and Ppk from individual measurement data. Compare short-term process capability with long-term process performance, then use the result to investigate centering, variation, stability, and expected defect risk.
Capability: Cp and Cpk
Cp shows potential spread against tolerance; Cpk also reflects how well the process is centered.
Performance: Pp and Ppk
Pp and Ppk use overall variation to show longer-term process performance and possible drift.
