Statistical Quality Control (SQC):

The most common business application for Statistical Quality Control involves the application of statistical theory to performance measurement to determine whether variation in process performance is statistically significant or insignificant. This distinction is important; as it allows management to determine whether or not variation in a measurement should be acted upon or not. Acting upon insignificant variation is referred to as "tampering", and actually do more harm than good. Significant variation is that which should either be "locked in" (when beneficial to the organization) or "rooted out" (when harmful to the organization).
