Origins of Six Sigma methodology

From a quality approach to a client-focused management

Origins of the Sigma Methodology

Originally, 6 Sigma is quality process born at the heart of Motorola.
First limited to SPC (Statistical Process Control) techniques, it became quickly a real management method which includes the whole company functions.
Six Sigma has later been perfected by other groups, such as General Electric for example, which displayed it with success.
Besides, Motorola was one of the first worldwide companies to receive the famous "Malcolm Baldridge", a highly-coveted prize which rewards US companies achieving total quality.
Please note :
1. Six sigma goes rather well with other approaches to industrial management and organisation such as the lean management system.
2. The greek letter "Sigma" symbolizes statistical variability.
