Six Sigma is a registered trademark of Motorola that aims to eliminate defects. It was developed in the 1980s at Motorola to reduce production defects and has since been used to improve business processes. Six Sigma defines different levels of practitioners from yellow belt to master black belt and uses methodologies like DMAIC (Define, Measure, Analyze, Improve, Control) and DMADV (Define, Measure, Analyze, Design, Verify) to drive process improvement and innovation. When properly implemented, Six Sigma aims for no more than 3.4 defects per million opportunities.

1. SIX SIGMA

2.  A registered service mark and trademark of Motorola incorporation.
 Sigma statistical meaning- how far something is from perfection.
 The intention is to eliminate defects that impair the quality of a product or
service.
 Looking at fundamentals ways in which businesses operate in order to find a
better way for improving services.

3.  Since the 1920's the word 'sigma' has been used by mathematicians and
engineers as a symbol for a unit of measurement in product quality
variation
 In the mid-1980's engineers in Motorola Inc in the USA used 'Six Sigma' an
informal name for an in-house initiative for reducing defects in production
processes.

5. Yellow belt
Green belt
Black belt
Master black belt

6. DMAIC PROCESS
 D -DEFINE
 M -Measure
 A- Analyse
 I - improve
 C -control

7.  D – define
 M - measure
 A - analyse
 D - design
 V - verify

9.  A six sigma process is one in which 99.9999966% of the
products manufactured are statistically expected to be free
of defects.

10.  Combination of 6 sigma ideas with lean manufacturing has
created a methodology named lean six sigma.
 Promotes business and operational excellence.
 Serves as foundation for innovation throughout the
organization.
