  1. SIX SIGMA

  2. Six Sigma Means 3.4 Defects in 1,000,000 - MOTOROLA • Six Sigma is a business concept that answers customer’s demand for high quality and Defect-free Business process. • Six Sigma was born in Motorola and developed by Mikel J. Harry. • Motorola won Malcolm Baldridge Quality Award. • Six Sigma is carried out as projects and mostly uses DMAIC method

  3. Eg: Godrej -G E Assembly Plant • Defective Components were coming at the rate of 3,00,000 for one Million Parts. • Applying Six Sigma saved Rs 4 Crores • Mr. Vijay Krishna, C.E.O, Godrej-G E. “We’re not talking about intangible savings here. Six Sigma has given us the power to measure and control costs. And that goes straight to our bottom line”

  4. Upper and Lower Standards (Specifications) Single Standard (Specification) Spec (Upper) Spec (Lower) Spec Out of Spec Out of Spec In Spec Out of Spec In Spec Probability Probability Probability PROCESS CAPABILITY Process capability is simply a measure of how good a metric is performing against established standard(s).

  5. CONCEPT OF SIX SIGMA USL LSL

  6. CONCEPT OF SIX SIGMA USL Process LSL Cp = Design Width / Process Width Mean Cp = USL –LSL / UCL - LCL

  7. SIGMA SCALE OF DEFECTS(1.5 σ shift)
