OBJECTIVE

This term paper is designed as a part of the curriculum. It helped me to tap into the power of the Six Sigma movement that’s transforming some of the world’s most successful companies. Six Sigma initiatives have tallied billions of dollars in savings, dramatic increases in speed, strong new customer relationships—in short, remarkable results and rave reviews.

SIX SIGMA
Six Sigma is now according to many business development and quality improvement experts, the most popular management methodology in history. Six Sigma is certainly a very big industry in its own right, and Six Sigma is now an enormous 'brand' in the world of corporate development. Six Sigma began in 1986 as a statistically-based method to reduce variation in electronic manufacturing processes in Motorola Inc in the USA. Today, around twenty years on, Six Sigma is used as an all-encompassing business performance methodology, all over the world, in organizations as diverse as local government departments, prisons, hospitals, the armed forces, banks, and multi-nationals corporations. While Six Sigma implementation continues apace in many of the world's largest corporations, many organizations and suppliers in the consulting and training communities have also seized on the Six Sigma concept, to package and provide all sorts of Six Sigma 'branded' training products and consultancy and services. Six Sigma has also spawned many and various business books on the subject. Six Sigma, it might seem, is taking over the world.

The original and technically correct spelling seems to be Six Sigma, rather than 6 Sigma, although in recent years Motorola and GE have each since developed their own sexy Six Sigma logos using the number six and the Greek sigma character. Six Sigma is now a global brand and something of a revolution. But what is Six Sigma? Sigma is a measurement that indicates how a process is performing. Six Sigma stands for Six Standard Deviations (Sigma is the Greek letter used to represent standard deviation in statistics) from mean. Six Sigma methodologies provide the techniques and tools to improve the capability and reduce the defects in any process. Six Sigma is a fact-based, data-driven philosophy of improvement that values defect prevention over defect detection. Philosophy: The philosophical perspective views all works as a process that can be defined, measured, analyzed, improved & controlled (DMAIC). Processes require inputs & produce outputs. If you control the inputs, you will control the outputs. This is generally expressed as the y= f (x) concept. Set of Tools: Six Sigma as a set of tools includes all the qualitative and quantitative techniques used by the six sigma experts to drive process improvement. A few such tools include statistical process control (SPC), Control charts, failure mode & effects analysis, process mapping etc....
