Building an acceptance chart: These handy tools can help you meet specification limits


There are some processes that, due to their nature, are expected to have unavoidable shifts in their average value but which are still able to satisfy customer-established specifications. This situation occurs when the standard deviation of the process at the various average values of the process is very small relative to the tolerance width, that is, the difference between the upper and lower specification limits. In usual statistical process control terms, such a process is not in control but may be able to produce acceptable product.
