A stable and predictable process means its performance can be statistically forecasted, allowing for the prediction of its ability to meet customer specifications. This does not necessarily mean that common or random causes of variation have been eliminated, nor does it imply that the process produces the exact same result every time or that the process averages vary in terms of standard deviations.
