Question: Explain how environment and the Five M’s can affect processes used in the following: ? A hardware store ? A hospital ? An accounting firm ? A newspaper ? A factory ? A new-car dealership Explain the relationship that exists between the histogram and the control chart. Contrast the histogram’s characteristic of representing a “snapshot” of a process with a control chart. Defend the statement that the operator of the process should be the owner and data plotter of the control chart, as opposed to a person from quality assurance or engineering, for example. Comment on the significance of this statement: “Control chart parameters must be statistically derived and cannot simply be specifications or some arbitrary values that are based on production expectations.”
