Control Charts

  • Merton R. Hubbard


The ancient adage “A picture is worth a thousand words,” is somewhat time worn but far from worn out. In a world where statistics and columns of numbers are not well understood, a picture of a process may be far easier to grasp than a quality summary laced with standards deviations, averages, equations, and numerical computations. The control charts used in statistical quality control represent a picture of a process. When used and continuously updated on the production floor, these charts represent a moving picture of the process.
