This document provides an introduction to Six Sigma and the Six Sigma Green Belt certification. It discusses the origins and evolution of Six Sigma at Motorola and GE in the 1980s and 1990s. It also outlines the Six Sigma DMAIC methodology, various Six Sigma roles, Lean principles, and the ASQ Six Sigma Green Belt certification process and body of knowledge topics.
4. What is Six Sigma
1. Method to achieve defect level of 3.4 PPM
2. Method to achieve breakthrough improvements
(10X or 10 times improvements in terms of Cost,
Quality and Delivery)
5. • In 1980 ,Motorola -Survival problem - with fierce
Japanese competition
• CEO Bob Gelvin – determined not to loose parental
company Motorola !!
Evolution of Six Sigma - Motorola
6. Evolution of Six Sigma - Motorola
• Bill Smith gave a solution – reduce defects from
30,000 ppm to 3 ppm (in 8 years )
• Goal of 68 % improvements for every employee
every year in all units of Motorola ( for 10 fold
improvements every 2 years )
7. Evolution of Six Sigma - Motorola
• Actions taken at Motorola
• Strong emphasis on training with 300 million $
budget ( Return was 800 million $ within 2 years)
• Global Benchmarking
8. • CEO Jack Welch – (in 1995 ) had goal of 10 fold
improvements within a year
• Six Sigma was adopted as Philosophy
Evolution of Six Sigma - GE
9. A structured Approach to continuous Improvement
• A Philosophy
• A Statistical Measurement
• A Metric
• A Business Strategy
• A measuring system
• Make fewer mistakes in all
we do
• Helps gauge adequacy of
product, process and services
• Good quality reduces cost
What is Six Sigma?
10. • 20,000 lost articles of mail per hour
• Unsafe drinking water almost 15
minutes each day
• 5,000 incorrect surgical operations per
week
• 2 short or long landings at most major
airports daily
• 200,000 wrong drug prescriptions each
year
• No electricity for almost 7 hours each
month
• Seven lost articles of mail per hour
• One minute of unsafe drinking water
every seven months
• 1.7 incorrect surgical operations per
week
• One short or long landing at most
major airports every five years
• 68 wrong drug prescriptions each
year
• One hour without electricity every 34
years

12. Key Role Responsibilities
Champions
Sponsors
• Sponsors the project
• Business process owner
• Primary responsibility is to remove road block for team from achieving the goal
• Responsible for making major decisions during the ‘improve’ stage
Master Black
Belts
• Full time member of the team
• Responsible for providing detail technical consultation internally, if necessary
• Six sigma content professor
Black Belts • Full time member of the continues improvement / quality team
• Responsible for leading the management of the team and project
• Official content owner
Green Belts • User of the process(es) and functional organization being improved
• Responsibilities are identical to those of a black belt but maintains a full time
position in the functional department
Deployment Team • Individual members responsible for executing specific tasks
• Usually gets selected based on technical background and closeness of his/her
position to the identified quality process.
Roles in Six Sigma Journey
14. ASQ Certification
1. Six Sigma Green Belt Certification - CSSGB
2. ASQ Certification Requirements
3. ASQ Body of Knowledge
15. Certification is formal recognition by ASQ that an individual has
proficiency within, and a comprehension of, a specified body of
knowledge.
1. Each certification candidate is required to pass a written
examination that consists of multiple choice questions that
measure comprehension of the Body of Knowledge.
2. The Six Sigma Green Belt Certification is a four-hour, 100 multiple-
choice question examination.
3. Examinations are conducted twice a year, in June and December, by
local ASQ sections and international organizations.
4. All examinations are open-book. Each participant must bring his or
her own reference materials.
Six Sigma Green Belt Certification
