Six Sigma seminar by Nehall

  1. 1. Six Sigma Prepared by:- Guided by: - Dixit Nehal Subhashbhai Mr. Saurabh Tandel (4th Computer, Roll No: 5108)
  2. 2. 1.0 Introduction • “A methodology to manage process variations that cause defects and to systematically work towards managing variation to eliminate those defects.” • The objective of Six Sigma is to deliver to the end customer:- – High performance – Reliability – Value
  3. 3. 1.0 Introduction CTD.. 1.1 What is Quality?  Internal orientation— company’s perspective.  The degree to which a specific product conforms to a design or specification.  Differences in quality amount to differences in the quantity of some desired ingredient or attribute.  External orientation— customer’s perspective.  Fitness for use.  Quality consists of the capacity to satisfy wants. Fig 1.1.1 In the modern era cut throat competition demands Quality
  4. 4. 1.0 Introduction 1.1 What is Quality? (CTD..) Quality Is: Conformance to  Requirements- Meeting standards!  Fitness for use-  Meeting & Exceeding  customer’s needs! Quality Dimensions-  Reliability  Responsiveness  Assurance  Empathy 
  5. 5. 1.0 Introduction 1.1 What is Quality? (CTD..)  Importance of Quality  Quality Control Implement testing procedures against quality definitions.  Quality Testing Activities & processes for specific testing tasks.
  6. 6. 2.0 Six Sigma Concept  σ : Indicates standard deviation.  Used to relate the ability of a process to perform defect free work.  The higher the value the better the process is performing and the lower the probability that a defect will occur.
  7. 7. 2.0 Six Sigma Concept CTD.. 2.2 Why Six? Sigma Level Defects Per Cost Of Poor Sigma % Good % Bad DPMO Million Quality Opportunities 1 30.9% 69.1% 691,462 2 308,537 N/A 2 69.1% 30.9% 308,538 (Noncompetitive companies) 3 93.3% 6.7% 66,807 3 66,807 25-40% of sales 4 6210 15-52% of sales 4 99.38% 0.62% 6,210 (Industry Average) 5 99.977% 0.023% 233 5 233 5-15% of sales 6 3.4 <1% of sales 6 99.9997% 0.00034% 3.4 (World Class) 2.2.1 Table showing variation and 2.2.2 Table showing how world striking difference that Six Sigma is Class companies eliminate their having compared to all defect rate to minima and hence compatible previously devised optimize their standards .

Shewhart - control chart | 1994 1995 special vs. common Kano cause variation >> Model process problems. 1970’s 1986 Jack Welch - IshiKawa GE Wilfred Pareto Diagram introduces 1960 Bill Smith – 6Sigma @ 80/20 Motorola 1949 1924 1896 Alex Osborn of BBDO sets 1941 “brainstorming” definitions 1815 Gauss Uses Normal Curve for error analysis, probability 1735 De Moivre Creates normal Curve
  9. 9. 2.0 Six Sigma Concept 2.4 Definitions • “A term used to describe a measure of quality control that is higher than quot;normal“.” • “A measure of quality that strives for near perfection. The Six Sigma process uses data and rigorous statistical analysis to identify quot;Defectsquot; in a process or product, reduce variability, and achieve as close to zero defects as possible.” • “A disciplined data driven approach and methodology for eliminating defects in any process from manufacturing to transactional & from product to service. It allows organizations to make customer focused, data driven decisions that ultimately yield a reduction in product defect rate, increase profits and employee morale and high Fig 2.4.1 Defining the working quality products-a accentuating situation for model using Six Sigma to have everyone involved.” minimum defect i.e. zero defect ideally.
  10. 10. 2.0 Six Sigma Concept 2.4 Definitions CTD.. Six Sigma is actually many things: • A Goal • A Vision • A Metric • A Strategy • A Methodology • An Application
  11. 11. 3.0 Six Sigma Methodology
  12. 12. 3.0 Six Sigma Methodology • the project goals and customer (internal and external) requirements  Objectives Project’s purpose and scope defined  Outputs Clear statement of intended improvement, A list of what is important to the customer(s)
  13. 13. 3.0 Six Sigma Methodology • The process to determine current performance  Objectives Focus the improvement effort by gathering information on the current situation.  Outputs Data that pinpoints problem location or occurrence. A more focused problem statement.
  14. 14. 3.0 Six Sigma Methodology • Determine the root cause(s) of the defects.  Objectives Identify root cause(s) and confirm them with data.  Outputs Theory that has been tested and confirmed
  15. 15. 3.0 Six Sigma Methodology • The process by eliminating defect root causes.  Objectives Try out and implement solutions that address root causes  Outputs Planned, tested actions that should eliminate or reduce the impact of the identified root causes.
  16. 16. 3.0 Six Sigma Methodology  Objectives Evaluate the solutions and the plan. Outline steps for on-going improvements.  Outputs Completed documentation of results, learning, and recommendations.
  17. 17. 3.0 Six Sigma Methodology CTD… Other Methodologies are :- DFSS -Design For Six Sigma DMADV-Define, Measure, Analyze, Design and Verify. DMADOV -Define, Measure, Analyze, Design, Optimize and Verify. IDOV -Identify, Design, Optimize and Validate DMEDI-Define, Measure, Explore, Develop and Implement.
  18. 18. 4.0 Six Sigma Tools • Brainstorming • Flow charts and process maps • Pareto charts • Control charts • Cause and Effect Diagram (Fishbone Diagram) • XY Matrix • Hypothesis Testing • Failure Mode and Effects Analysis (FMEA) • Design of Experiments (DOE)
  19. 19. 5.0 Six Sigma Implementation Six Sigma Implementation Model Steps :  Establishing Management Commitment  Information gathering  Training – Master Black Belt,Black Belt,Green Belt,Champion.  Developing Monitoring Systems  Business Processes To Be Improved Are Chosen  Conducting six sigma projects
  20. 20. 6.0 Why To Adopt Six Sigma? Opportunities Traditional Six Sigma Quality (Three Sigma Quality) 300,000 letters delivered 3,000 miss-deliveries 1 miss-delivery 500,000 computer restarts 4,100 crashes < 2 crashes 500 years of end of month 60 months would not .018 months would not closings balance balance For every week of TV 1.68 hours of dead air 1.8 seconds of dead air broadcasting (per channel) Cleaning 1500 sq ft of 4 sq ft still dirty after Dirty carpet smaller than a carpet cleaning postage stamp
  21. 21. 7.0 Six Sigma Applications • Health care • Laboratory • Banking • Insurance • Construction • Education
  22. 22. 8.0 Six Sigma Success Stories
  23. 23. 8.1 Cheapest Six Sigma •Achieved by Dabbawala association running in Mumbai. •Daily 2 lac lunches are moved every day by estimated 5000 dabbawala’s at very moderate rate. •600000:1 defect ratio. •Six Sigma, ISO 2000 certified and this whole system runs by means of illiterate Lecture MBA’s. •No Strike for 116 years. •Acclaimed by Forbes magazine. New York Times based on survey that this industry expand 5 to 10 percent per year.
  24. 24. 9.0 Conclusion • Today’s World is too competitive and to survive in this cut- throat race of success and World leaders one has to adopt the Six Sigma Methodology in any sector with any designations. • As we have seen from the world class dignified companies like MOTOROLA,SEIMENS,MICROSOFT,GE,GM to Mumbai’s DABBAWALLAS every one can attain this standard if employees and all other adjoining entities unites under the common goal for success of company for betterment of individuals for promoting National Prestige . • Hence we can draw the conclusion that the equation y = f(x) is the basic equation of life. You can be sure of the output only if you can control the inputs. In other words the output of a process is the function of its inputs.
