OpEx-Introduction to Six Sigma

Introduction to Six Sigma – Guide Overview

This guide offers a structured introduction to Six Sigma, presenting the methodology as a practical framework for improving process efficiency, reducing defects, and enhancing product and service quality.

Purpose and Origins

Explains Six Sigma’s aim of minimizing variability and defects to achieve consistent quality. Traces its origin to Motorola in 1987 and its widespread adoption across major global organizations seeking operational excellence.

Key Concepts

 Covers essential terminology and metrics, including:

• Cost of Poor Quality (COPQ) – financial impact of defects.
• Critical to Quality (CTQ) – key attributes affecting customer satisfaction.
• Defects per Million Opportunities (DPMO) – a measure of process performance.
  Practical examples are provided to illustrate these concepts.

Process Models

•  Describes the structured approaches:

• DMAIC (Define, Measure, Analyze, Improve, Control) for optimizing existing processes.
• DMADV (Define, Measure, Analyze, Design, Verify) for designing new processes.
  The guide emphasizes systematic steps to ensure measurable improvements.

Roles and Responsibilities

 Outlines Six Sigma team roles and responsibilities, including Yellow Belt, Green Belt, Black Belt, Master Black Belt, and Champion, detailing how each contributes to project success and process improvement.

Philosophy and Benefits

 Highlights the Six Sigma philosophy of data-driven decision-making, focus on process excellence, and continuous improvement. Benefits include enhanced quality, operational efficiency, reduced waste, and higher customer satisfaction.
