INTRODUCTION TO HALF A DOZEN SIGMA CONTENT FLOW…? Understanding Six Sigma? Definition? Community at Six Sigma illustrations? Six Sigma Scale? So why Six Sigma? Six Sigma Methodologies , Tools? Specify? Measure? Assess? Improve? Control WHAT’S WITHIN A NAME? Sigma is the Ancient greek language letter symbolizing the standard deviation of a population of data.? Sigma is a measure of standard deviation (the info spread)?? HALF A DOZEN SIGMA IS …? A statistical idea that measures a process regarding defects – at the half a dozen sigma level, there three or more. 4 problems per mil opportunities?
A defect is definitely anything that results in customer discontentment Six Sigma is a methodology and synonymous with quality? HOW OFTEN ARE WE DELIVERING IN TIME? If the target time is usually 30 A few minutes, the charts below show two figure with common at twenty-five Mins 40 mins 31 mins s s zero 10 back button 30 2 sigma 20 40 50 0 twelve 20 by 30 4 sigma 45 50? How many standard deviations could you “fit” within just customer objectives? Managing by average will not tell the full story.
The regular and the deviation together demonstrate what’s occurring. MANAGING IN THE SIGMA SCALE Sigma you 2 a few 4 your five 6 % Good % Bad 40. 9% 69. % 93. 3% DPMO 691, 462 308, 538 66, 807 69. 1% 30. 9% 6. 7% 99. 38% 99. 977% 0. 62% 0. 023% 6, 210 233 a few. 4 99. 9997% 0. 00034% SAMPLES OF THE SIGMA SCALE In a world in 3 sigma…? In a community at six sigma…? You will find 964 U. S. air travel cancellations every day. The police make 7 false arrests just about every 4 mins. 1 U. S. airline flight is terminated every 23 days. There are fewer than 4 bogus arrests monthly.?? In one hour, 47, 283 international long distance calls are inadvertently disconnected.? It would take much more than 2 years to find the same quantity of dropped worldwide calls.
SO WHY SIX SIGMA? • For GE, Half a dozen Sigma added more than money 2 billion dollars to the final conclusion in 1999 exclusively • Motorola saved much more than $ 12-15 billion in the first ten years of it is Six Sigma effort AlliedSignal reports keeping $ you, 5 billion through 6 Sigma. • • Half a dozen Sigma is all about practices that help you eliminate defects and deliver product or service that fulfill customer technical specs How are these kinds of savings noticed? cost of scrap? cost of remodel? cost of excessive cycle times and gaps? Benefits of added capacity and man-hours
