Do you know wht six sigma is?

Make it simple, six sigma is a measurement scale upon which improvement / performance can be gauged or overall methodology that provides standardized problem-solving tools improvement. Sigma actually is standard deviation. Six sigma mean a process with 2Cpk, or say that 0.001ppm (0.001 defect / error found out of 1 million). However, the six sigma process used is morden six sigma, it is 1.5 sigma shifted which provide a result 3.4ppm. The above information is from http://www.sixsigmais.com

Six Sigma is a methodology to manage process variations that cause defects and to systematically work towards managing variation to eliminate those defects[1]. Defects are defined as unacceptable deviation from the mean or target. The objective of Six Sigma is to deliver high performance, reliability, and value to the end customer. The process was pioneered by Bill Smith at Motorola in 1986[2] and was originally defined[3] as a metric for measuring defects and improving quality, and a methodology to reduce defect levels below 3.4 Defects Per (one) Million Opportunities (DPMO), or put another way, a methodology of controlling a process to the point of plus or minus six sigma (standard deviations) from a centerline. Six Sigma has now grown beyond defect control. Six Sigma is a registered service mark and trademark of Motorola, Inc[4]. Motorola has reported over US$17 billion in savings[5] from Six Sigma to date. In addition to Motorola, companies which also adopted six sigma methodologies early-on and continue to practice it today include Honeywell International (previously known as Allied Signal), Raytheon and General Electric (introduced by Jack Welch). The three companies have reportedly saved billions of dollars thanks to the aggressive implementation and daily practice of six sigma methodologies.[citation needed] Recent six sigma trends lies in the advancement of the methodology with integrating to TRIZ for inventive problem solving and product design. from the site http://www.wikipedia.org greetings. : )
