system; unstable, unpredictable, or inappropriately variable.
Shift (as in data behavior) A sudden change in process outputs manifesting as non-
sustained, vastly different performance or sustained, moderately different performance.
Inferential Statistics Numbers derived through calculations that draw more general
conclusions from sample data about a population; use measured statistics from the sample to
interpret/ extrapolate data behaviors for a broader population.
Control (Limits) Stability, manifest by minimal variation in a process or its outputs; limits
are statistically derived, usually set at 3 SD from the mean.
Capability The ability of process outputs to meet customer requirements (specifications)
within a targeted range (see specification limits).
