In this section, we will explore the history of Six Sigma, understand what Six Sigma certification entails, and how this structured methodology has transformed the professional and corporate landscape.
History of Six Sigma
The concept of Six Sigma was developed by Bill Smith in 1986 while he was working at a large electronics manufacturer. At the time, Smith recognized the need for a more consistent and data-driven approach to product quality. His efforts were aimed at improving manufacturing processes that failed to meet established quality standards. His revolutionary ideas laid the groundwork for the Six Sigma framework we use today.
Smith was influenced by earlier pioneers in quality management. Walter A. Shewhart is often credited with introducing the concept of statistical quality control. He developed the Plan-Do-Check-Act cycle, a model for continuous improvement that serves as the foundation of many quality management approaches. Edwards Deming expanded on Shewhart’s work and promoted statistical methods for quality control on a global scale. He is known for his contributions to improving industrial production, particularly in post-war Japan.
Another influential figure was Sir Ronald Aylmer Fisher, whose contributions to statistical science laid the groundwork for several methods still used in Six Sigma today. These include the use of distributions such as the F-distribution and concepts like the p-value, which are critical in hypothesis testing and process validation.
Six Sigma as a methodology gained major traction in the late 1990s when major corporations adopted it to streamline operations and improve quality. One of the most well-known adopters was General Electric. Under the leadership of Jack Welch, the company integrated Six Sigma into its core operational strategies and achieved substantial financial savings as a result. Motorola also reported billions in savings due to implementing Six Sigma strategies in its processes.
