six sigma training, history, definitions - six sigma and quality management glossary
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, twenty-something 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 manay and various business books on the subject. Six Sigma, it might seem, is taking over the world.
Interestingly while Six Sigma has become a very widely used 'generic' term, the name Six Sigma is actually a registered trademark of Motorola Inc., in the USA, who first pioneered Six Sigma methods in the 1980's. 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 s.
Six Sigma is now a global brand and something of a revolution. But what is Six Sigma?...
six sigma definitions
The answer is that Six Sigma is lots of things.
First, Six Sigma is arguably a very clever way of branding and packaging many aspects of Total Quality Management that exist in their own right, regardless of the development of Six Sigma. Read the section about Total Quality Management and 'Excellence' and you will understand this.
Six Sigma is lots of different things because it had different meanings over time, and also because it is now interpreted in increasingly different ways. And Six Sigma is still evolving.
The UK Department for Trade and Industry says Six Sigma is:
"A data-driven method for achieving near perfect quality. Six Sigma analysis can focus on any element of production or service, and has a strong emphasis on statistical analysis in design, manufacturing and customer-oriented activities." June 2005.
Here's the DTI fact-sheet on Six Sigma - please note this is Crown copyright.
Motorola Inc., who first developed the methodology in the mid-late1980's and who provide extensive Six Sigma training and consultancy services, provide the following definitions:
six sigma according to motorola
"...Six Sigma has evolved over the last two decades and so has its definition. Six Sigma has literal, conceptual, and practical definitions. At Motorola University (Motorola's Six Sigma training and consultancy division), we think about Six Sigma at three different levels:
Essentially, Six Sigma is all three at the same time."
"...Six Sigma as a Metric: The term "Sigma" is often used as a scale for levels of 'goodness' or quality. Using this scale, 'Six Sigma' equates to 3.4 defects per one million opportunities (DPMO). Therefore, Six Sigma started as a defect reduction effort in manufacturing and was then applied to other business processes for the same purpose.."
"...Six Sigma as a Methodology: As Six Sigma has evolved, there has been less emphasis on the literal definition of 3.4 DPMO, or counting defects in products and processes. Six Sigma is a business improvement methodology that focuses an organization on:
"..At the heart of the methodology is the DMAIC model for process improvement. DMAIC is commonly used by Six Sigma project teams and is an acronym for:
"...Six Sigma Management System: Through experience, Motorola has learned that disciplined use of metrics and application of the methodology is still not enough to drive desired breakthrough improvements and results that are sustainable over time. For greatest impact, Motorola ensures that process metrics and structured methodology are applied to improvement opportunities that are directly linked to the organizational strategy. When practiced as a management system, Six Sigma is a high performance system for executing business strategy. Six Sigma is a top-down solution to help organizations:
"..The Six Sigma Management System drives clarity around the business strategy and the metrics that most reflect success with that strategy. It provides the framework to prioritize resources for projects that will improve the metrics, and it leverages leaders who will manage the efforts for rapid, sustainable, and improved business results.."

General Electric (GE), the first large-scale adopters and advocates of Six Sigma after Motorola, and considered by most experts to have been responsible for Six Sigma's rapidly achieved high profile, provide the following definitions of Six Sigma:
