This follows because inspection controls are being put in place to confirm that the changes do initially increase quality and that they continue to do so.

SQC Theorye, practitioners of six sigma have demonstrated that it is possible to derive value from statistical methods while having little or no knowledge of statistical theory. However, understanding the implications of probability theory (assumptions to predictions) and inference theory (data to informed as

DOE: Robust Designcally only a small fraction of units fail to conform to specifications. If characteristic values were consistent, then either 100% of units would conform or 0%. Robust design methods seek to reduce the effects of input variation on a system’s outputs to improve quality.
