  • Six sigma is a part of 68-95-99.7 rule
  • This is method of probability determination
  • 1 sigma = 31% efficiency
  • 2 sigma = 69.2% efficiency
  • 3 sigma = 93.32% efficiency
  • 4 sigma = 99.379% efficiency
  • 5 sigma = 99.977% efficiency
  • 6 sigma = 99.9997% efficiency

what do we do
What do we do
  • Sigma six uses DMAIC method

for improving production

  • Define high-level project goals and the current process.
  • Measure key aspects of the current process and collect relevant data.
  • Analyze the data to verify cause-and-effect relationships.
  • Improve or optimize the process based upon data analysis using techniques like Design of experiments.
  • Control to ensure that any deviations from target are corrected before they result in defects.

DFSS-Design For Six Sigma
  • Sigma six uses DMADV method

for development of new products

  • Define design goals that are consistent with customer demands and the enterprise strategy.
  • Measure and identify CTQs
  • Analyze to develop and design alternatives,
  • Design details, optimize the design,
  • Verify the design, set up pilot runs, implement the production process
