Six Sigma means a measure of quality that strives for near 
perfection. 
Six Sigma is a disciplined, data-driven approach and 
methodology for eliminating defects (driving towards six 
standard deviations between the mean and the nearest 
specification limit) in any process -- from manufacturing 
to transactional and from product to service.

six sigma is a highly disciplined process that helps us 
focus on developing and delivering near perfect products 
and services.

the word is a statistical term that measures how far a 
given process deviates from perfection.the central idea 
behind sisx sigma is that if u can measure how 
many"defects"you have in process you can systematically 
figure out to eliminate them and get as close to 'zero 
defects' as possib;e

six sigma prvides a technology and tool to improve the 
capablity & to reduce the defect in any process.To achieve 
this six sigma uses a methodology known as "DMAIC"

D-define opportunity 
M-Measure performance
A-Analyse opportunity
I-improve performance 
c-control performance
intially it wa used in motorolla in its manufacturing 
division.But now a days it is used fields banking,call 
centres, medicene...etc...

Six Sigma:
A quality discipline that focuses on product and service
excellence to create a culture that demands perfection
on target, every time!

Six Sigma quality levels
produces 99.9997% accuracy, with only 3.4 defects per
million opportunities.

Six Sigma is designed to dramatically upgrade a companys
performance, improving quality and productivity. Using
existing products, processes, and service standards,
 They go for Six Sigma MAIC methodology to upgrade
performance. 

MAIC is defined as follows:

Measure  Gather the right data to accurately assess
          a problem.
Analyze  Use statistical tools to correctly identify the   
root causes of a problem.
Improve  Correct the problem (not the symptom).
Control  Put a plan in place to make sure problems stay
fixed and sustain the gains.

Key Roles and Responsibilities:

The key roles in all Six Sigma efforts are as follows:
 Sponsor  Business executive leading the organization.
 Champion  Responsible for Six Sigma strategy,
deployment, and vision.
 Process Owner  Owner of the process, product, or
service being improved responsible for long-term
sustainable gains.
 Master Black Belts  Coach black beltsexpert in all
statistical tools.
 Black Belts  Work on 3 to 5 $250,000-per-year
projects; create $1 million per year in value.
 Green Belts  Work with black belt on projects.

thank u

Six Sigma at many organizations simply means a measure of 
quality that strives for near perfection. Six Sigma is a 
disciplined, data-driven approach and methodology for 
eliminating defects (driving towards six standard 
deviations between the mean and the nearest specification 
limit) in any process -- from manufacturing to 
transactional and from product to service.


Plz correct me if i m wrong...

Six sigma is a methodology to solve any problem of our work 
area .It's a data driven approch which talks about 
variation & Mean analysis.It talks about elemination of 
cause of variation.It talks about finding out the causes 
which we call potential Xs.All potential Xs are analysed as 
per applicable method & checked for actual cause of the 
problem.All appproved cause of the problem is called Vital 
Xs.All vital Xs are improved with mangement support & all 
improvement action are controlled by applicable dept.This 
the complete cycle of Sixsigma Methodology.Which is defined 
as Define->Measure ->Analyse->Improve -> Control.
