SPC Review
Review the section “Statistical Process Control Defined.” 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.”
