FUNDAMENTAL OF SIX SIGMA
NEED OF SIX SIGMA
Sigma (the lower-case Greek letter σ) is used to represent standard deviation of a population.
A sigma quality level offers an indicator of how often defects are likely to occur, where a higher sigma quality level indicates a process that is less likely to create defects.
Standard deviation can be thought of as a comparison between expected results or outcomes in a group of operations, versus those that fail.
Six Sigma is the definition of outcomes as close as possible to perfection. With six standard deviations, we arrive at 3.4 defects per million opportunities, or 99.99966 %.

SIX SIGMA SUCCESS STORIES
MOTOROLA
Only two years after launching Six Sigma, Motorola was honored with the Malcolm Baldrige National Quality Award.
The company’s total employment has risen from 71,000 employees in 1980 to over 130,000 today.
More than a set of tools, though, Motorola applied Six Sigma as a way to transform the business, a way driven by communication, training, leadership, teamwork, measurement, and a focus on customers.
