The term "Six Sigma" comes from a field of statistics known as process capability studies.●it referred to the ability of manufacturing processes to produce a

very high proportion of output within specification.●Processes that operate with "six sigma quality" over the short term

are assumed to produce long-term defect levels below 3.4 defects per million opportunities (DPMO).

It was developed by Motorola Inc., USA on 1986 who provide extensive Six Sigma training and consultancy services.Other early adopters of Six Sigma who achieved well-publicized

success:●Honeywell/Allied Signal●General Electric- method introduce by Jack Welch●Fortune 500 Org.- (late 1990’s) the aim of reducing costs and

improving quality●Lean Manufacturing

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 it is still evolving.o a number of defects per million opportunities.◦ Six Sigma is used as a term for a management style, with the ultimate goal

of high levels of customer satisfaction.◦ It 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.

◦ It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organization

◦ It is the most popular management methodology in history◦ is arguably a very clever way of branding and packaging many aspects of

Total Quality Management that exist in their own right◦ Is an enormous 'brand' in the world of corporate development

SIX SIGMA DEFINITIONS

Six Sigma at three different levels:a) 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..“

b) As a methodology Six Sigma is a business improvement methodology that focuses an

organization on:Understanding and managing customer requirementsAligning key business processes to achieve those requirementsUtilizing rigorous data analysis to minimize variation in those

processesDriving rapid and sustainable improvement to business processes.."

Six Sigma According To Motorola

c) As a 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.."

Six Sigma is a high performance system for executing business strategy. Six Sigma is a top-down solution to help organizations:

Align their business strategy to critical improvement efforts Mobilize teams to attack high impact projects Accelerate improved business results Govern efforts to ensure improvements are sustained.."

At the heart of the methodology, Six Sigma projects follow two project methodologies (composed of five phases each).

SIX SIGMA METHODS

DMADV ("duh-mad-vee“) also known as DFSS (Design For Six Sigma) is used for projects aimed at creating new product or process designs. Define goals and strategy Measure and identify CTQs (Critical To Quality) Analyze to develop and select the best design. Design Verify the design

Six Sigma is a highly disciplined process that helps us focus on developing and delivering near-perfect products and services.

Six Sigma revolves around a few key concepts◦ Critical to Quality: Attributes most important to the customer◦ Defect: Failing to deliver what the customer wants◦ Process Capability: What your process can deliver◦ Variation: What the customer sees and feels◦ Stable Operations: Ensuring consistent, predictable processes to

improve what the customer sees and feels◦ Design for Six Sigma: Designing to meet customer needs and

process capability..."

Six Sigma According To General Electric

Six Sigma According To Isixsigma: Isixsigma organization, the biggest online 'community' of Six Sigma

practitioners, was founded in 2000, and is owned and run by a number of 'quality professionals'.

"Six Sigma is a rigorous and disciplined methodology that uses data and statistical analysis to measure and improve a company's operational performance by identifying and eliminating 'defects' in manufacturing and service-related processes, defined as 3.4 defects per million opportunities.

Six Sigma According to UK Department for Tradeand Industry:

"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."

Sigma is a quality improvement methodology. Perhaps the most objective way of looking at Six Sigma is to

recognize that the Six Sigma methodology essentially provides a framework, and importantly a strongly branded corporate initiative, for an organization to:◦ train its people to focus on key performance areas◦ understand where the organization wants to go (its strategy,

related to its market-place)◦ understand the services that the organization's customers need

most◦ understand and better organize main business

processes that deliver these customer requirements◦ measure (in considerable detail) and improve the effectiveness

of these processes.

Six Sigma - Other Points Of Note

 late-1980's  Motorola extended the Six Sigma methods to its critical business processes, and Six Sigma formalized in-house 'branded' name for a performance improvement methodology.

1991 Motorola certified its first 'Black Belt' Six Sigma experts, indicates the beginnings of the formalization of the accredited training of Six Sigma methods.(CEO Bob Galvin)◦ Allied Signal adopted the Six Sigma methods. (CEO Lawrence Bossidy )

1995, General Electric's (CEO Jack Welch) implement Six Sigma in GE, and by 1998 GE claimed that Six Sigma had generated over three-quarters of a billion dollars of cost savings.

HISTORY OF SIX SIGMA

mid-1990's Six Sigma had developed into a transferable 'branded' corporate management initiative and methodology, notably in General Electric and other large manufacturing corporations, but also in organizations outside the manufacturing sector.

year 2000, Six Sigma was effectively established as an industry in its own right, involving the training, consultancy and implementation of Six Sigma methodology in all sorts of organizations around the world.

Six Sigma quickly became not only a hugely popular methodology used by many corporations for quality and process improvement, it is also a subject of many and various training and consultancy products and services around which developed very many Six Sigma support organizations.
