Abstract
We all know that when we repeat an action we may not get the same result. An athlete may not run a mile in the exact same time twice, you may not get the same number of french fries in two orders at McDonald’s, or two scoops of ice cream will not be exactly the same. Therefore, “variability” is present in the outcomes of all repeated actions. Process variability, where measurement plays a role, is a major concern in the real world. The main objective in process control is to identify the sources of variation and look for ways to control the variation.
