  • 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

What do we do l.jpg
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.

Conclusion l.jpg

  • It’s more product oriented

    than any other model of development
