Six Sigma

Six Sigma is a strategy used within business to manage quality. It is applied across many sectors. It aims to reduce the amount of defects that occur in products. By reducing this variability in the output of produced items, cost can be reduced or profit increased. Defect elimination is an inherently sustainable goal, as defective products result in wasted resources, wasted energy, and wasted labor.

While Six Sigma has now entered the common language in certain business and manufacturing circles, “Six Sigma” is registered by Motorola, Inc., as a trademark. Originally implemented by Motorola as a statistically based way of improving the defect rate in the manufacturing of electronic devices, Six Sigma has now become widely recognized throughout a variety of industry sectors.
