2. MEANING
A term used in statistics to represent standard deviation, an
indicator of the degree of variation in a set of a process
3. 3
DEFINITION
Business Definition
A break through strategy to significantly improve customer
satisfaction and shareholder value by reducing variability in
every aspect of business.
Technical Definition
A statistical term signifying 3.4 defects per million
opportunities.
4. What is Six Sigma?
• A goal of near perfection in meeting customer requirements
• A sweeping culture change effort to position a company for
greater customer satisfaction, profitability and competitiveness
• A comprehensive and flexible system for achieving,
sustaining and maximizing business success; uniquely driven by
close understanding of customer needs, disciplined use of
facts, data, and statistical analysis, and diligent attention to
managing, improving and reinventing business processes

5. Why Six Sigma ?
Mail Delivery
99 % defect free (3.8 ) means 20,000 lost articles per hour
While delivery at 6 (99.99966 % defect free) means 7 articles lost per
hour
Electricity
99 % defect free (3.8 ) means no electricity for 7
hours per month
While at 6 (99.99966 % defect free) it means 1
hour no electricity every 34 years
Surgeries
99 % defect free (3.8 ) means 5000 errors
per week
While at 6 (99.99966 % defect free) means
1.7 errors per week

7. ORIGIN OF SIX SIGMA
Motorola company that invented Six Sigma.
The term “Six Sigma” was coined by Bill Smith, an engineer
with Motorola
Late 1970s - Motorola started experimenting with problem
solving through statistical analysis
1987 - Motorola officially launched it’s Six Sigma program
Motorola saved more than $ 15 billion in the first 10 years of
its Six Sigma effort

Define
Analyze
Improve
Define: Define who your customers
are, and what their requirements are
for your products and services – Their
expectations. Define your team goals,
project boundaries, what you will focus
on and what you won’t. Define the
process you are striving to improve by
mapping the process.
13. Six Sigma DMAIC Process
Measure
Control
Define
Analyze
Improve
Measure: Eliminate guesswork and
assumptions about what customers need
and expect and how well processes are
working. Collect data from many sources
to determine speed in responding to
customer requests, defect types and how
frequently they occur, client feedback on
how processes fit their needs, how clients
rate us over time, etc. The data collection
may suggest Charter revision.

Analyze
Improve
Analyze: Grounded in the context of the
customer and competitive environment,
analyze is used to organize data and look
for process problems and opportunities.
This step helps to identify gaps between
current and goal performance, prioritize
opportunities to improve, identify sources
of variation and root causes of problems
in the process.

Improve: Generate both obvious and
creative solutions to fix and prevent
problems. Finding creative solutions by
correcting root causes requires
innovation, technology and discipline.

Improve
Control: Insure that the process
improvements, once implemented, will
“hold the gains” rather than revert to
the same problems again. Various
control tools such as statistical process
control can be used. Other tools such
as procedure documentation helps
institutionalize the improvement.
17. Six Sigma DMADV Process

Design
Design: Develop detailed design
for new process. Determine and
evaluate enabling elements.
Create control and testing plan for
new design. Use tools such as
simulation, benchmarking, DOE,
Quality Function Deployment
(QFD), FMECA analysis, and
cost/benefit analysis.

Design
Validate: Test detailed design
with a pilot implementation. If
successful, develop and execute a
full-scale implementation. Tools
in this step include: planning
tools, flowcharts/other process
management techniques, and
work documentation.
19. The Growth Of Six SIGMA
The company that perfected Six Sigma
Jack Welch launched Six Sigma at GE in Jan,1996
At GE, Six Sigma added more than $ 2 billion to the bottom
line in 1999 alone.

Who are Implementing Six Sigma
At least 25% of the fortune 200 claim to have a serious six
sigma program
Financial - Bank of America, GE Capital,
Electronics - Allied Signal, Samsung, Sony
Chemicals - DuPont, Dow Chemicals
Manufacturing - GE Plastics, Johnson and Johnson,
Motorola, Nokia, Microsoft, Ford.
Airline - Singapore, Lufthansa, Bombardier
And hundreds of others in Americas, Europee, Sub
Continent
22. Company Annual Savings
