Cp
≥
1.33 : Data tightly distributed.
Cpk
≥
1.33 : Data well inside spec limits.
Cp > 1.00 : Data tightly distributed. If it
were centered between the spec limits,
no data would lie beyond those limits.
Cpk < 1.00 : Some data is outside the
spec limits.
Cp < 1.00 : Data not tightly distributed. If
it were centered between the spec
limits, some data would still lie outside
those limits.
Cpk < 1.00 : Some data is outside the
spec limits.
Cp = 1.00 : Data fills entire spec range.
Cpk = 1.00 : Data fills entire spec range.
