  3. 3. CONTENTSIntroductionUnderstanding Six SigmaBackground and growth of Six sigmaMethodologyKey role of six sigmaWhat make it differentBenefitsCertificate of Six Sigma
  4. 4. A highly disciplined process that helps us focus on developingand delivering near-perfect products and services. The word Six Sigma is a statistical term that measures howfar a given process deviates from perfection.The central idea behind Six Sigma is that if you can measurehow many “defects” you have in a process, you cansystematically figure out how to eliminate them and get as closeto “zero defects” as possible.
  5. 5. MEANINGA term used in statistics to represent standard deviation, anindicator 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. 6
  7. 7. Understanding Six Sigma Degree of variation; Sigma is a letter in the Greek Alphabet Level of performance in terms of defects Statistical measurement of process capability Benchmark for comparison Process improvement methodology It is a Goal Strategy for change; A commitment to customers to achieve an acceptable level of performance 7

  9. 9. 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
  10. 10. 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.
  11. 11. Six Sigma Certified Dabbawalla’s of Mumbai• Existing since the 1890s.• The tiffin box delivery service was started by Mahadeo Havaji Bacche.• People recruited from villages who were not able to earn a good living.• Engaged in transport of lunch boxes from home to office.• Daily 4000-5000 dabbawallas carry 1,75,000 – 2,00,000 tiffin boxes everyday.

  17. 17. DMADValso known as DFSS ("Design For Six Sigma")
  18. 18. Define Phase: design goals that areconsistent with customer demands and the enterprise strategy. Measure Phase: Identify andmeasure CTQs (characteristics that are critical to quality), product capabilities, production process capability, and risks.
  19. 19. Analyze Phase: Analyze, develop and design alternatives, create a high- level design and evaluate design capability to select the best design. Design Phase: Design the details, optimize the design, and plan fordesign verification. This phase may require simulations
  20. 20. Verify Phase: Verify the design, set up pilot runs, implement the production process and hand it over to the process owners.
  21. 21. DMAIC V/S DMADV• DMAIC is used for projects aimed at improving an existing business process.• DMADV is used for projects aimed at creating new product or process designs.
  22. 22. Key Roles for Six Sigma Master black Belt Black Belts Green Belts Yellow belt White belt Team members
  23. 23. Master Black BeltMaster Black Belts, act as in-housecoaches on Six Sigma. They devote100% of their time to Six Sigma. Theyguide Black Belts and Green Belts.Apart from statistical tasks, theirtime is spent on ensuring consistentapplication of Six Sigma acrossvarious functions and departments.
  24. 24. Master black belt should have• Two-plus years of Black Belt experience• Five-plus years of business experience• Mastery of the tools of Six Sigma process improvement (DMAIC),• Completion of at least five Black Belt projects with significant business results• Experience in managing cross-functional projects, strong ability to lead others without direct authority• Strong change management skills• Experience in delivering Black Belt and Green Belt training• Ten or more Black Belts or Green Belts coached to successful project completion and certification• Excellent written and verbal communication and presentation skills
  25. 25. Black BeltsBlack Belts operate under MasterBlack Belts to apply Six Sigmamethodology to specific projects.They devote 100% of their time to SixSigma. They primarily focus on SixSigma project execution, whereasChampions and Master Black Beltsfocus on identifyingprojects/functions for Six Sigma
  26. 26. Black belt should have• He should have experience of 1-2 yr and carried out 4-8 projects• He must be expert in problem solving,data collection and analysis.• He must be organizational savvy.• He must focus on leadership and understanding of administrative system and processes.
  27. 27. Green Belts• Green Belts are the employees who take up Six Sigma implementation along with their other job responsibilities, operating under the guidance of Black Belts.
  28. 28. Green belt should have• Operates in support of or under the supervision of a Six Sigma of Black Belt.• Analyses and solves quality problems.• Involved in quality improvement projects.• Participated in a project, but has not led a project.• Has at least three years of work experience.• Has ability to demonstrate their knowledge of Six Sigma tools and processes.
  29. 29. Who are Implementing Six Sigma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, Europe, Sub Continent 30
