While there may be some differences in what principles to include to define Six Sigma as a philosophy, many agree that Six Sigma is based on the principles of: If your specification is that far away, then Six Sigma will be defined as a process having 3.4 defects per million opportunities (DPMO). By adding and subtracting the value of three standard deviations to the mean or average of your data, you should encompass approximately 99.73% of your data, according to the Empirical Rule and relates to the Normal Distribution.Ī process is often described as being Six Sigma if the closest specification is at least six standard deviations away from the mean. Sigma (σ) is a Greek letter and symbol defining the standard deviation of a population. Six Sigma as a statistical symbol and metric Then Six Sigma methodologies and tools are used to identify and reduce or remove process variation and improve the process, all within the context of customer expectations and requirements. Lean Six Sigma first emphasizes the use of Lean methodologies and tools to identify and remove waste and increase process velocity. Today, you will see most organizations using Lean Six Sigma rather than the pure Six Sigma used by the early adopters of Six Sigma. Mikel Harry trains the first wave of Master Black Belts at GE. They become a driving force for the expansion of Six Sigma.ġ995 - General Electric started their Six Sigma journey in 1995 under the leadership of Jack Welch, the CEO. Richard Schroeder establish the Six Sigma Academy as the prime contractor for implementing Six Sigma at Allied Signal. Anecdotally, this took place during a golf game.ġ994 - Dr. Bossidy then tells his friend Jack Welch, the CEO of GE, about Six Sigma.
Motorola was one of the three winners during this inaugural year.ġ993 - Allied Signal, under the leadership of Larry Bossidy, adopted Six Sigma. organizations for performance excellence. Handpicked Content: Should You Calculate Your Process Sigma?ġ987 - The Malcolm Baldrige National Quality Award was created to recognize U.S. Smith and Harry worked together to come up with a four-stage problem-solving approach: measure, analyze, improve, control (MAIC), which became a cornerstone for the Six Sigma process, later called DMAIC. Smith is known as the Father of Six Sigma. Mikel Harry and CEO Bob Galvin, developed the idea and term Six Sigma to significantly reduce product defects. Edwards Deming, at the invitation of General McArthur, went to Japan to explain the application of statistical concepts in industrial processes.ġ954 - Joseph Juran was invited to visit Japan to share his quality concepts.ġ986 - Bill Smith, an engineer at Motorola along with several other people including Dr. PDCA served as the basis for the development of the Six Sigma methodology, DMAIC.ġ950 - Dr. Shewhart also introduced the PDCA (Plan-Do-Check-Act) in 1929 which was made popular by Dr. Shewhart developed the control chart to better understand the difference between common and special cause variation. 1913 - Henry Ford introduced his automobile assembly line and the concept of product standardization.ġ924 - Dr.
