SIX SIGMA
– INTRODUCTION :
Six Sigma is
a highly disciplined process that helps us focus on developing and delivering
near-perfect products and services.
Origin of Six
Sigma:
- ·
Six Sigma originated at Motorola in the early 1980s, in
response to achieving 10X reduction in product-failure levels in 5 years.
- ·
Engineer Bill Smith invented Six Sigma, but died of a
heart attack in the Motorola cafeteria in 1993, never knowing the scope of the
craze and controversy he had touched off.
- ·
Six Sigma is based on various quality management theories
(e.g. Deming's 14 point for management, Juran's 10 steps on achieving quality).
Features
of Six Sigma:

- ·
Six Sigma is a business-driven, multi-dimensional
structured approach for:

o Lowering Defects
o Reducing process variability

The word Sigma is a
statistical term that measures how far a given process deviates from
perfection.
The central idea behind Six
Sigma: If you can measure how many "defects" you have in a process,
you can systematically figure out how to eliminate them and get as close to
"zero defects" as possible and specifically it means a failure rate
of 3.4 parts per million or 99.9997% perfect.
