2. INTRODUCTION
WHAT IS SIX SIGMA?
Six Sigma at many organizations
simply means a measure of quality
that strives for near perfection.
3. Purpose of six sigma :
To make customer happier and increase
profits
Introduction to Six Sigma
4. A highly disciplined process that helps us focus on
developing and delivering near-perfect products and services.
The word Six Sigma is a statistical term that measures how
far a given process deviates from perfection.
The central idea behind Six Sigma is that 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.
5. MEANING
A term used in statistics to represent standard deviation,
an indicator of the degree of variation in a set of a process
6. 6
DEFINATION
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.
7. Current Leadership
Challenges
• Delighting Customers.
• Reducing Cycle Times.
• Keeping up with Technology Advances.
• Retaining People.
• Reducing Costs.
• Responding More Quickly.
• Structuring for Flexibility.
• Growing Overseas Markets.
8. SIX SIGMA
• Six Sigma is a highly disciplined process
that helps a company focus on developing
and delivering near-perfect products and
services.
• Why “sigma”? The word is a statistical
term that measures how far a given
process deviates from perfection.
9. What is Six Sigma?
• It is a methodology for continuous
improvement
• It is a methodology for creating products/
processes that perform at high standards
• It is a set of statistical and other quality
tools arranged in unique way
• It is a way of knowing where you are and
where you could be!
• It is a Quality Philosophy and a
management technique
10. What is 6-Sigma?
• Six-Sigma is an integrated quality improvement
framework, which aims at ensuring no more
than 3.4 defects per million opportunities.
• At the heart of the Six-Sigma methodology lies a
process improvement framework known as
DMAIC (Define, Measure, Analyse, Implement,
Control).
• It brings a rigour to process redesign, which
takes into account the detailed, and dynamic
complexity found in today’s health care systems.
11. Six Sigma is not
• A standard
• A certification
• Another metric like percentage
12. SIX SIGMA
•The central idea behind Six Sigma is
that if you can measure how many
" defects” you have in a process, you
can systematically determine how to
eliminate those and approach “zero
defects”.
13. Six Sigma
Six Sigma provides maximum
value to companies in the forms
of increased profits and maximum
value to consumers with high-
quality products and services at
the lowest possible cost.
14. Origin of Six Sigma
• 1987 Motorola Develops Six Sigma
– Raised Quality Standards
• Other Companies Adopt Six Sigma
– GE
•Promotions, Profit Sharing (Stock Options), etc.
directly tied to Six Sigma training.
– Dow Chemical, DuPont, Honeywell,
Whirlpool
15. Six Sigma
• In 1986, Bill Smith, a senior engineer and scientist at Motorola,
introduced the concept of Six Sigma to standardize the way defects
are counted.
• Six Sigma provided Motorola the key to addressing quality
concerns throughout the organization, from manufacturing to
support functions. The application of Six Sigma also contributed to
Motorola winning the Malcolm Baldrige National Quality award in
1988.
• Since then, the impact of the Six Sigma process on improving
business performance has been dramatic and well documented by
other leading global organizations, such as General Electric, Allied
Signal, and Citibank.
• Today, Motorola continues to implement Six Sigma throughout its
own enterprise, and extends the benefit of its Six Sigma expertise to
other organizations worldwide through Motorola University.
• Six Sigma was derived from the statistical term of sigma which
measures deviations from perfection.

24. Six Sigma
It is a Philosophy
– Anything less than ideal is an
opportunity for improvement
– Defects costs money
– Understanding processes and
improving them is the most
efficient way to achieve lasting
results
It is a Process
– To achieve this level of
performance you need to:
Define, Measure, Analyse,
Improve and Control
It is Statistics
– 6 Sigma processes will
produce less than 3.4 defects
per million opportunities

4 6,210 15%-25% of sales
5 233 5%-15% of sales
6 3.4 < 1% of sales
Each sigma shift provides a 10% net income improvement
Cost of Poorly Performing Processes (CP3)
Sigma (s) is a measure of “perfection” relating to
process performance capability … the “bigger the
better.” A process operating at a “Six Sigma” level
produces only 3.4 defects per million opportunities
(DPMO) for a defect. Without dedication of
significant and appropriate attention to a process,
most processes in leading companies operate at a
level between 3 and 4 sigma.
Why is Six Sigma Important?
27. Cost of Poorly Performing
Processes
The cost to deliver a quality product can account for as
much as 40% of the sales price.
For example, a laser jet printer purchased for $1,000 may
have cost the manufacturer $400 in rework just to make
sure that you took home an average-quality product.
For a company whose annual revenues are $100 million
and whose operating income is $10 million, the cost of
quality is roughly 25% of the operating revenue, or $25
million.
If this same company could reduce its cost of achieving
quality by 20%, it would increase its operating revenue by
$5 million – or 50% of the current operating income.
28. … and the Hero • We don’t know what we don’t know.
• We can’t do what we don’t know.
• We won’t know until we measure.
• We don’t measure what we don’t value.
• We don’t value what we don’t measure.
• Typical Results: companies that properly
implement Six Sigma have seen profit margins
grow 20% year after year for each sigma shift (up
to about 4.8s to 5.0s. Since most companies start
at about 3s, virtually each employee trained in Six
Sigma will return on average $230,000 per
project to the bottom line until the company
reaches 4.7s. After that, the cost savings are not
as dramatic.
• However, improved profit margins allow
companies to create products & services with
added features and functions that result in
greater market share.

Have you ever…
• Shot a rifle?
• Played darts?
32. More about limits
Good quality:
defects are
rare (Cpk>1)
Poor quality:
defects are
common (Cpk<1)
Cpk measures “Process Capability”
If process limits and control limits are at the same location, Cpk = 1. Cpk ≥ 2 is
exceptional.

44. CTQ (Critical-To-Quality)
• CTQ characteristics for the process,
service or process
• Measure of “What is important to
Customer”
• 6 Sigma projects are designed to
improve CTQ
• Examples:
– Waiting time in clinic
– Spelling mistakes in letter
– % of valves leaking in operation
45. Defect Opportunity
• Circumstances in which CTQ can fail to
meet.
• Number of defect opportunities relate to
complexity of unit.
• Complex units – Greater opportunities of
defect than simple units
• Examples:
– A units has 5 parts, and in each part there are 3
opportunities of defects – Total defect opportunities
are 5 x 3 = 15
46. DPO (Defect Per Opportunity)
• Number of defects divided by number of
defect opportunities
• Examples:
– In previous case (15 defect opportunities), if 10 units
have 2 defects.
– Defects per unit = 2 / 10 = 0.2
– DPO = 2 / (15 x 10) = 0.0133333
47. DPMO (Defect Per Million
Opportunities)
• DPO multiplies by one million
• Examples:
– In previous case (15 defect opportunities), if 10 units
have 2 defects.
– Defects per unit = 2 / 10 = 0.2
– DPO = 2 / (15 x 10) = 0.0133333
– DPMO = 0.013333333 x 1,000,000 = 13,333
Six Sigma performance is 3.4 DPMO
13,333 DPMO is 3.7 Sigma
50. Six Sigma Methodology
• Six Sigma has two key methodologies:
• DMAIC and DMADV.
• DMAIC is used to improve an existing
business process.
• DMADV is used to create new product
designs or process designs in such a way
that it results in a more predictable, mature
and defect free performance.
52. Statistical Process Control
Methodology
Statistical process control is an important part of Six
Sigma methodology, which proceeds through the
following steps, also called DMAIC (Define, Measure,
Analyze, Improve and Control):
• 1. Define - benchmarking, process flow mapping,
flowcharts
• 2. Measure - defect metrics, data collection, sampling
• 3. Analyze - Fishbone diagrams, failure analysis, root
cause analysis
• 4. Improve - modeling, tolerance control, defect control,
design changes
• 5. Control - SPC control charts, performance
management
53. Six Sigma Five Phases
Basic methodology consists of the following five phases
DMADV (Define, Measure, Analyze, Design, and Verify):
• Define - formally define the goals of the design activity that
are consistent with customer demands and enterprise
strategy.
• Measure - identify CTQs (Critical to Quality), product
capabilities, production process capability, risk assessment,
etc.
• Analyze - develop design alternatives, create high-level
design and evaluate design capability to select the best
design.
• Design - develop detail design, optimize design, and plan
for design verification. This phase may require simulations.
• Verify - verify design, setup pilot runs, implement
production process and handover to process owners. This
phase may also require simulations.

65. Design for Six Sigma
Applications of Six Sigma that focus on the design or
significant redesign of products and services and their
enabling processes so that from the beginning customer
needs and expectations are fulfilled are known as
Design for Six Sigma or DFSS.
The focal aim of DFSS is to create designs that are resource
efficient, capable of exceptionally high yields, and are
robust to process variations. This aim leads to the DFSS
algorithm
Define-Measure-Analyze-Design-Verify (DMADV).
66. Define

Design for Six Sigma (DFSS)
All new products at GE are designed using a DFSS
algorithm.
Define customer requirements and
goals for the process, product or service
Measure and match performance
to customer requirements.
Analyze and assess the design for
the process, product or service.
Design and implement the array of
new processes required for the new
process, product or service.
Verify results and maintain
performance.
Six Sigma: How Do We
Design?
68. 1. Total Quality Management involves designing and
developing new systems and processes and ensures
effective coordination among various departments. New
Processes are developed based on various customer
feedbacks and researches.
2. The main focus of Total quality management is to maintain
existing quality standards whereas Six Sigma primarily
focuses on making small necessary changes in the
processes and systems to ensure high quality.
3. The process of Total quality management does reach to a
saturation level after a certain period of time. After
reaching the saturation stage, no further improvements in
quality can be made. Six Sigma on the other hand seldom
reaches the saturation stage by initiating a next level
quality process.
69. 4. The process of Total quality management involves improvement
in existing policies and procedures to ensure high quality. Six-
Sigma focuses on improving quality by minimizing and eventually
eliminating defects from the system.
5. The process of total Quality management ensures that every
single member associated with the organization is working towards
the improvement of existing processes, systems, services and
work culture for long term quality products/ services. Six Sigma, on
the other hand focuses on first identifying and eventually removing
various defects and obstacles which might come in the way of
organization’s success.
6. In a layman’s language total quality management emphasizes
on improving the existing policies and making necessary changes
in the systems to ensure superior quality products and services.
Organizations practicing Six Sigma are focused on removing
errors and defects to ensure high quality products.
70. 7. Total Quality management is a less complicated process than Six
Sigma. Six-Sigma involves specially trained individuals whereas total
quality management does not require extensive training. The process
of Six Sigma creates special levels for employees who are only eligible
to implement the same. Employees trained for Six Sigma are often
certified as “Green Belts” or “Black Belts” depending on their level of
proficiency. Six-Sigma requires participation of only certified
professionals whereas total quality management can be referred to a
part time activity which does not require any special training. Six-
Sigma can be implemented by dedicated and well trained
professionals.
8. Six-Sigma is known to deliver better and effective results as
compared to total quality management. The process of Six Sigma is
based on customer feedbacks and is more accurate and result
oriented. Customer feedbacks play an important role in Six Sigma.
Experts predict that six sigma will outshine total quality management in
due course of time.
71. DFSS is changing GE. With it GE can build on all of its
Capabilities and take all of its product and process
designs to a new level of world-class performance
and quality.
The essence of DFSS is predicting design quality up
front and driving quality measurement and
predictability improvement during the early design
phases-a much more effective and less expensive way
to get to Six Sigma quality than trying to fix problems
further down the road.

101. Focus of Six Sigma
• Accelerating fast breakthrough
performance
• Significant financial results in 4-8
months
• Ensuring Six Sigma is an extension
of the Corporate culture, not the
program of the month
• Results first, then culture change!
102. • There is nothing new. It only proves defects and
defectives counts offer tangible, measurable results.
•It is corrective action system rather than taking a
preventive and proactive approach to problems.
•It is merely about appraisal system and that appraisal
programs aren’t useful. In realty, appraisals are great
tools for identifying and tracking improvements, which
is critical to any project.
•Critics have suggested that Six Sigma did not bring
quality improvement in all the organizations where it
was implemented.
It depends on the tools and authorizations.

Components of Six Sigma are
people power and process
power
