Understanding Six Sigma for Beginners

What is Six Sigma?

Six Sigma is a data-driven methodology that aims to improve processes by reducing defects and variability. The term "Six Sigma" refers to a quality level where processes produce only 3.4 defects per million opportunities. It was originally developed by Motorola in the 1980s and has since been widely adopted across industries.

Introduction to Six Sigma Methodology:

At its core, Six Sigma involves five phases: Define, Measure, Analyze, Improve, and Control (DMAIC). These steps guide teams through understanding a process, identifying problems, implementing solutions, and ensuring sustained improvements.
