Six Sigma Certification: A Guide to Understanding the Levels, Benefits, and How to Start

What is Six Sigma?

Six Sigma is a structured methodology used to improve business processes by reducing variability and eliminating defects. Originally developed by Motorola in the 1980s and later popularized by companies like GE, Six Sigma relies on data-driven tools and statistical analysis to achieve consistent quality and operational excellence.
