A Note About Statistical Control • A process being in statistical control does not necessarily indicate that the process is "good enough" for manufacturing. A further condition is that the UCL and LCL on the Average Chart must be inside specification limits. For the final product, specification limits are generally dictated by the customer.

Statistical process control, 17 Apr 2014 SPC FOR SHORT PRODUCTION RUNS – LITERATURE. REVIEW. Traditional control charts assume that data for estimating the process Control charts show if a process is in control or out of control. They show the variance of the output of a process over time, such as a measurement of width, length or temperature. Control charts compare this variance against upper and lower limits to see if it fits within the expected, specific, predictable and normal variation levels.
