Six Sigma (Dmaic)

Six Sigma (DMAIC) Six Sigma is not what it used to be; it has evolved throughout the centuries and become what it is today. According to the article, The History of Six Sigma, Carl Fredrick Gauss (1777-1855) introduced the normal curve and six sigma as a measurement standard that can be traced back to him. As a measurement standard, six sigma is traced back to Walter Shewhart who explained that three sigma is the point where a process needs correction. There were many measurement standards that were later introduced, but the recognition for the term “six sigma” goes to a Motorola engineer named Bill Smith. (Page 1) Motorola ended up copywriting the term in their organization. According to The History of Six Sigma, Motorola engineers determined quality levels did not provide enough granularities. Geoff Tennant explained in his book Six Sigma: SPC and TQM in Manufacturing and Services:
"Six Sigma is many things, and it would perhaps be easier to list all the things that Six Sigma quality is not. Six Sigma can be seen as: a vision; a philosophy; a symbol; a metric; a goal; a methodology."
There has been a lot of progression with Six Sigma over time. It has become more like a quality system like TQM, total quality management, or ISO, International Organization for Standardization. (Page 1)
There have been a few industries that are involved with the history of Six Sigma. Motorola is one, along with Allied Signal, and General Electric. According to www.beexcellence.org, Bossidy, who was top management at Allied Signal, generated significant improvements with Six Sigma. Lawrence Bossidy was at General Electric, but left in 1991. Allied Signal improved both the effectiveness and efficiency of Six Sigma by focusing on customer measures of effectiveness. They saved millions of dollars and improved customer reputation. There was no cost-cutting through downsizing or lay-offs with these improvements. (Page 1)
