What is Six Sigma?A statistical measure of variationFull Six Sigma equals 99.9997% accuracyMethodology for improving key processesA tool box of quality and management tools for problem resolutionA business philosophy focusing on continuous improvementAn organized process for structured analysis of data
ProcessesEverything we do can be considered a process or part of a processEvery process can be characterized by:Average performanceVariationProcesses are performing optimally when the result of the process is at the expected value (meaning there is minimal variation).
History of Six SigmaMotorola developed the Six Sigma methodology in the mid-1980s as a result of recognizing that products with high first-pass yield rarely failed in use
Statistical term dates back to the 1800s (Carl Frederick Gauss)
Six Sigma MethodologyD.M.A.I.C, (Define, Measure, Analyze, Improve, Control)Provides a logical sequence for applying existing problem solving tools and conceptsRepackaging of existing tools and conceptsVarious quality/management tools applied at each stepProject sponsor review recommended at conclusion of each step before moving to next step
Six Sigma Road Map
When to use Six Sigma?Unknown causes/situationsProblems are common place and not well definedWhen broad spectrum approach is inappropriateWhen other problem solving methods failIn a complex situation with many variables
Six Sigma Belts3 levels (or Belts)Based on level of competence in understanding and applying related toolsGreen belt basic analytical tools; works on less complex projectsBlack belt emphasis on application and analysis; works projects with help from Green beltsMaster Black belt understands application and statistical theory behind application; trains other belts; leads project reviewsActual definition and competencies for each belt can vary by organization and training institutions
Why adopt Six Sigma?Defined process for problem solvingProven methodology to solve problemsConsistency with resultsFocus on the bottom line which encourages credibility/support from the top of the organization
Its not all Plain Sailing!Adoption requires a cultural change in order gain best resultsTop Management must be patient there is no quick fixSix Sigma is about getting the right answer, not just any answer
Points of Attention Lies, damn lies, and statistics CAVE people, (Citizens Against Virtually Everything)Internal Sabotage.Lack of understandingFear of ChangeThere are more ways to fail than to succeed!
Six Sigma SummaryIts amazing what can be known when we look at data differently.DMAIC is not for every projectWhen applied correctly, DMAIC will produce consistently better results than most other methodsNew Culture at many organizations todayVery marketable A Six Sigma approach works!
