  1. Six Sigma Overview Presented by: <<Name>> <<Title>> <<Organisation>>

  2. Agenda • What is Six Sigma? • History of Six Sigma • Six Sigma Methodology • When to use Six Sigma? • Different Six Sigma belts? • Why adopt Six Sigma? • Points of Attention? • Summary?

  3. What is Six Sigma? • A statistical measure of variation • Full Six Sigma equals 99.9997% accuracy • Methodology for improving key processes • A “tool box” of quality and management tools for problem resolution • A business philosophy focusing on continuous improvement • An organized process for structured analysis of data

  4. Processes • Everything we do can be considered a process or part of a process • Every process can be characterized by: • Average performance • Variation • Processes are performing optimally when the result of the process is at the expected value (meaning there is minimal variation).

  5. History of Six Sigma • Motorola developed the Six Sigma methodology in the mid-1980’s as a result of recognizing that products with high first-pass yield rarely failed in use • Statistical term dates back to the 1800’s (Carl Frederick Gauss)

  6. Six Sigma Methodology • D.M.A.I.C, (Define, Measure, Analyze, Improve, Control) • Provides a logical sequence for applying existing problem solving tools and concepts • Repackaging of existing tools and concepts • Various quality/management tools applied at each step • Project sponsor review recommended at conclusion of each step before moving to next step

  7. Six Sigma Road Map

  8. When to use Six Sigma? • Unknown causes/situations • Problems are common place and not well defined • When “broad spectrum” approach is inappropriate • When other problem solving methods fail • In a complex situation with many variables

  9. Six Sigma Belts • 3 levels (or Belts) • Based on level of competence in understanding and applying related tools • Green belt – basic analytical tools; works on less complex projects • Black belt – emphasis on application and analysis; works projects with help from Green belts • Master Black belt – understands application and statistical theory behind application; trains other belts; leads project reviews • Actual definition and competencies for each belt can vary by organization and training institutions

  10. Why adopt Six Sigma? • Defined process for problem solving • Proven methodology to solve problems • Consistency with results • Focus on the “bottom line” which encourages credibility/support from the top of the organization

  11. It’s not all Plain Sailing! • Adoption requires a cultural change in order gain best results • Top Management must be patient – there is no quick fix • Six Sigma is about getting the right answer, not just any answer

  12. Points of Attention • “Lies, damn lies, and statistics” • CAVE people, (Citizens Against Virtually Everything) • Internal Sabotage. • Lack of understanding • Fear of Change There are more ways to fail than to succeed!

  13. Six Sigma Summary • Its amazing what can be known when we look at data differently. • DMAIC is not for every project • When applied correctly, DMAIC will produce consistently better results than most other methods • “New Culture” at many organizations today • Very marketable • A Six Sigma approach works!
