A Short Background

Six Sigma was developed by Bill Smith in 1986. Then an engineer at Motorola aimed to help improve the company’s devices which didn’t meet the quality standards at the time. He based the approach on statistical and quality control methods taught by Walter Shewhart, Ronald Fisher, and Edwards Deming.  

  • Walter Shewhart pioneered statistical quality control (SQC) and also came up with the Plan Do Check Act (PDCA) model (also known as the Shewhart Cycle).
  • Edwards Deming worked in Japan after World War II and played a big role in shaping quality control in Japanese manufacturing. He is credited with developing the sampling techniques used by the Department of Census and the Bureau of Labor Statistics in the US.
  • Sir Ronald Aylmer Fisher is considered “the single most important figure in 20th-century statistics.” His work popularized many statistical techniques used today. For instance, Student’s t-distribution, P-value, F-distribution, among others.
