DMAIC

____ is a letter in the Greek alphabet used to represent standard deviation, a measure of variation. Therefore a 6 ___ process is very consistent, with very little variation, and therefore, has a very small standard deviation, so small that a distance from the mean, or the average, to the nearest specification limit, is equivalent to six standard deviations, or six ___ (Σ σ ς).

Answer explanation

Sigma (Σ σ ς) is a letter in the Greek alphabet used to represent standard deviation, a measure of variation. Therefore a 6 Sigma process is very consistent, with very little variation, and therefore, has a very small standard deviation, so small that a distance from the mean, or the average, to the nearest specification limit, is equivalent to six standard deviations, or six sigmas (Σ σ ς). As a result, only 3.4 parts per million or less are out of specification.
