What is Process capability index?
In process improvement efforts, the process capability index or process capability ratio is a statistical measure of process capability: the ability of a process to produce output within specification limits. The concept of process capability only holds meaning for processes that are in a state of statistical control.
Process Capability Index Calculation
Formula:
where,
Cp = process capability index,
μ = estimated mean of the process,
T = target process mean,
σ = standard deviation,
Cpm = process capability index
