What is Six Sigma?

Six Sigma is a data-driven methodology used to improve business processes by identifying defects, minimizing errors, and increasing efficiency. The primary goal of Six Sigma is to achieve near-perfect quality by reducing process variations and improving performance.

The methodology focuses on:

  • Improving customer satisfaction
  • Reducing waste
  • Enhancing productivity

Six Sigma is widely used in:

  • Manufacturing
  • Healthcare
  • Information Technology
  • Banking and Finance
  • Logistics
  • Retail
  • Telecommunications

Six Sigma was first introduced by Motorola in the 1980s to improve manufacturing quality and reduce defects. Later, companies like General Electric popularized the methodology globally.

Over time, Six Sigma evolved into a complete business improvement strategy used across multiple industries. Today, organizations use Lean Six Sigma to achieve continuous improvement and maintain competitive advantage.
