  • Six Sigma has grown greatly in acceptance among thousands of companies, and has proven to be both a time and money saver when implemented properly. The basic goals of the Six Sigma methodology is the introduction of a measurement-based strategy that focuses on process improvement and variation reduction through the application of Six Sigma improvement programs Driving towards six standard deviations between the mean and the nearest specification limit DMEDI also has an alternative description: DMADV process (define, measure, analyze, design, verify

    • 3. What is Sigma?
      • Greek Letter
      • 6 Sigma = 3.4 defects per million

    • 5. 6 Sigma Definitions
      • Six Sigma is a measure of quality with a continuous improvement program looking for perfection
      • Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects
      • Six Sigma is a data-driven, disciplined approach to minimizing defects in any type of process (be it manufacturing or services).
      • The goal of Six Sigma is to statistically represent how a process is performed, and determine where defects can be eliminated. Six Sigma strives for just 3.4 defects per million - near perfection.
    • 6. What does the 6 & Sigma Mean?
      • Sigma is the statistical term for the standard deviation of a population (or the data that you have)
      • 6 Standard Deviations from the mean = 3.4 defects per million
    • 7. What is Standard Deviation?
      • Standard deviation is the statistical spread of data in relation to the mean. It indicates variation in a data set
    • 8. 6 Sigma Overview
      • 6 Sigma is a management philosophy
        • With techniques and tools to improve capability and reduce defects in any process
      • Project with strict Gateway reviews
        • DMAIC:Define, Measure, Analyse, Improve, Control
        • DMEDI: Define, Measure, Explore, Develop, Implement
      • Fully supportive framework from top down with full time focus of Black Belt
    • 9. Is it new?
      • Begun by Motorola, made famous by General Electric. Now practised by many and there are variations – e.g. Toyota
      • Reduce variability
        • Reduce mistakes, cut cost of quality
        • Improve quality
        • Retain customers and build reputation
        • Better margins and sales
