Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes.[4] It uses a set of quality management methods‚ including statistical methods‚ and creates a special infrastructure of people within the organization ("Black Belts"‚ "Green Belts"‚ etc.) who are experts in these methods.[4] Each Six Sigma project carried out within an organization follows a defined sequence of steps

Six Sigma is anticipated to maintain its dominance over all other existing quality improvement techniques because it is flexible and can be altered to suit the requirements of new businesses that might come up in the near future.

INTRODUCTION Six Sigma was developed at Motorola in mid 1980’s when Motorola Company declared 10X reduction in product-failure. Six Sigma was originally used to compute the defects during manufacturing processes‚ and to trim down the faults at every level in the processes. Motorola declared millions of savings by using this method. GE also used Six Sigma and declared that it save up around US $ 300 million to operating income. From the last decade there has been a major initiatives by various industries

Introduction to Six Sigma "Six Sigma" is the method of quality management which aims at achieving "six sigma". This method was introduced by Motorola in the 80’s. Nowadays it is beeing used by lots of international companies and institutions. Some people say that six sigma should be implemented into various sphere of life and the effect of this method (significant improvement of financial results by reducing costs of bad quality) is very important. In statistics "sigma" means standard deviation

Six Sigma Six Sigma is a methodological approach by which errors in a company’s current processes and plans are identified and strategies to fix the same are formulated. It is fact-based technique‚ involving a lot of data handling‚ which provides scientific results for cost cutting and reduction in waste of resources. It is also a fat–based‚ data–driven philosophy of quality improvement that values defect deterrence over defect exposure. It drives customer satisfaction and bottom-line results

Six Sigma: Definition and underlying theory§ Roger G. Schroeder a‚*‚ Kevin Linderman a‚1‚ Charles Liedtke b‚2‚ Adrian S. Choo c‚ Motorola originally developed Six Sigma in 1987 and targeted an aggressive goal of 3.4 ppm defects (Barney‚ 2002b; Folaron‚ 2003). In 1994 Larry Bossidy‚ CEO of AlliedSignal‚ introduced Six Sigma as a business initiative to ‘‘produce high-level results‚ improve work processes‚ expand all employees’ skills and change the culture’’ (ASQ‚ 2002‚ p. 14).

Six Sigma Some say‚ Robert Galvin invented Six Sigma in the 1880’s‚ instead‚ he applied methodologies that had been available since the 1920’s developed by luminaries such as: Shewhart‚ Deming‚ Juran‚ Ishikawa‚ Ohno‚ Shingo‚ Taguchi‚ and Shainin. The idea behind Six Sigma is you can measure how many defects you have in a process‚ you can systematically figure out how to eliminate them and as close to zero defects as possible. We use this highly disciplined Six Sigma process to help us focus
