As indicated in figure below [1], the normal probability distribution predicts a 3.4 defects per million opportunities (DPMO) for a Sigma Level of 4.5 and 0.002 DPMO for Sigma Level of 6. Motorola has determined, through various studies on process data collected for years, that the process average (mean) is likely to shift over the long term by +/- 1.5. 99.9995% 5 5.9 99.99966% 3.4 6 Yield DPMO Sigma.

And as the collection of repeated measurements piles up, a shape begins to form. Real data usually cluster around a central value, and the occurrence of data points farther and […] Common probability dictates that 99.73% of all outcomes will fall within 3 standard deviations of the mean (above or below); this is Three Sigma. For most purposes, this is a fine system. There are very few scenarios in daily life or most professions where 99.73% certainty or accuracy is not acceptable.

Probability is the ratio of number of favorable outcomes to the total number of possible outcomes. Se hela listan på lsssimplified.com Mathematically, the probability that some event, let’s call it E, occurs is expressed as: P(E) or Pr(E): The probability of an event occurring must be between 0 and 1: 0 P(E) 1 If an event cannot happen it has probability, P(E) = 0. If an event is certain to happen, its probability is, P(E) = 1. Why not 4.5 Sigma? The normal probability distribution predicts a 0.00034 percent defect rate when the nearest specification limit is 4.5 standard deviations away from the process average. That’s 3.4 parts-per-million (PPM). So why does Six Sigma require six standard deviations between the mean and the nearest specification limit?

Since Sigma Level looks at variation in a process and DPMO looks at the rate of producing defects in a process (i.e. outputs that are out of specification) it is natural to conclude that there is a correlation between them.

After we toss the coin, the probability that we get heads is 1 or 0.
