Six Sigma is a business process improvement system uniquely characterized by its Define, Measure, Analyze, Improve and Control (DMAIC) steps implemented through a customer-focused, data-driven, robust methodology.


The key concept of Six Sigma revolves around:

  • Understanding quality issues that are critical to customers.
  • Designing and manufacturing to ensure defect-free products or services are delivered to customers by improving process capability and reducing variation to ensure a stable business process.

Unlike Lean Manufacturing which focuses on “speeding” the process, Six Sigma looks at improving process accuracy and effectiveness.
