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 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

results of an exploratory study of six-sigma‚ suggest that the development of knowledge and learning communities is instrumental to sustaining six-sigma initiatives. Case studies highlight particular aspects of implementation and deployment efforts. The work presented in this report is to capture the current state of Six Sigma as well as to document the current practices of Six Sigma. Six key findings have been established. These include the interpretation of Six Sigma‚ tools and techniques‚ its development

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

What is Six Sigma? Six Sigma is a structured and disciplined process which is designed to deliver product and services which are perfect on a constant basis. Six Sigma means at many organizations are simply means a measure of quality that strives for near perfection. Six Sigma is associated with process capabilities of greater than 1.5‚ which is called ‘World class Performance’. Sigma is statistical terms which connotes with standard deviation of process measured about its mean. Six Sigma refers
