The History of Six Sigma

The roots of Six Sigma as a measurement standard can be traced back to Carl Frederick Gauss (1777-1855) who introduced the concept of the normal curve. Six Sigma as a measurement standard in product variation can be traced back to the 1920′s when Walter Shewhart showed that three sigma from the mean is the point where a process requires correction. Many measurement standards (Cpk, Zero Defects, etc.) later came on the scene but credit for coining the term “Six Sigma” goes to a Motorola engineer named Bill Smith. (Incidentally, “Six Sigma” is a federally registered trademark of Motorola).

In the early and mid-1980s with Chairman Bob Galvin at the helm, Motorola engineers decided that the traditional quality levels — measuring defects in thousands of opportunities – didn’t provide enough granularity. Instead, they wanted to measure the defects per million opportunities. Motorola developed this new standard and created the methodology and needed cultural change associated with it. Six Sigma helped Motorola realize powerful bottom-line results in their organization – in fact, they documented more than $16 Billion in savings as a result of our Six Sigma efforts.

Since then, hundreds of companies around the world have adopted Six Sigma as a way of doing business. This is a direct result of many of America’s leaders openly praising the benefits of Six Sigma. Leaders such as Larry Bossidy of Allied Signal (now Honeywell), and Jack Welch of General Electric Company. Rumor has it that Larry and Jack were playing golf one day and Jack bet Larry that he could implement Six Sigma faster and with greater results at GE than Larry did at Allied Signal. The results speak for themselves.

Six Sigma has evolved over time. It’s more than just a quality system like TQM or ISO. It’s a way of doing business. As Geoff Tennant describes in his book Six Sigma: SPC and TQM in Manufacturing and Services: “Six Sigma is many things, and it would perhaps be easier to list all the things that Six Sigma quality is not. Six Sigma can be seen as: a vision; a philosophy; a symbol; a metric; a goal; a methodology.” We couldn’t agree more.

It is a good information about how 6 sigma came into existence specially for someone like me who has no idea about this term or rather methodology as I came to know after reading this article.

it’s great a moment for me to identify the right at the right time.

It seems building into this great concept is the right thing to do. With management expectation so high on deliverables, I am sure that benefits are there to equip me with necessary tools.

as an emplyee of a company that has implemented six sigma. all i can see is an increased demand for the bottom line at the expense of the consumer and as our company has gone with this all out they probably are saving money right now because very little is being spent on maintaing the current infastructure that is in bad need of repair. and as a result we are loosing 80 THOUSAND CUSTOMERS in my buisness a week. thank you six sigma all to maximize the bottom line i understand that the bottom line is very emportant. but not so important that customer quality and satisfaction has to suffer.

But the savings is supposed to come from increased quality based on what the customer desires. If you are not giving the customer what they want then you are not following Six Sigma.
So it is not Six Sigma’s fault it is the people implementing it. The problem is management gets tunnel vision on cost reduction and that becomes the total focus instead of voice of the customer. Too much focus on the short run and stock prices.

This(Six sigma) is very right tools, concern with statistic. it provides uniqueness in production operation. Six sigma identify the variability in production operation specification, which is more important. Because whatever the specification is, it always concern with uniqueness of the objects, things. This is very clear methodlogy, tools,techniques or concept to statistical measurement, I’m very happy to know about this(Sis sigma). I would like to share my view with my Society concern with statistic, that is , most of the people(management) say that in day to day activity(in organisation) there is no need of numerical implementation, but I never belived this fact and ultimately I knew the fact about statistic, that what actually it is with the help of Six sigma.That’s all. thank’s

it is all about the business production of a particular business to sustain an accurate quality production

although i am a business student ,as for as my understanding of six sigma is,it is about scientific management and zero error production.

Forget six sigma or what ever it is …..statistics can derive results only but cant create leadership, it is a power within.

It is a very good introduction about 6-Sigma and can be starting point for the business students to learn more about it,
Thanks a lot. ( Jafar Lodhi )

The Six Sigma way of production is very much like ACE. It does change teh way you work and produce.

For me, Six Sigma is a tool box with a variety of tools to use when the need for a specific tool is required. If a tool is used incorrectly, it is useless, but when used properly, can save time, effort, money and aggravation. Learn how to use the six sigma tools to your advantage.

All the measures implemented by Six Sigma are to tackle gaps created by shorcomming of human brain. Our brain lags on capabilites such as picturising the status of the process by mesuring them by numerous parameters.This methodology/tool helps us to get the picture of the proceses status thus enabling us to diagnoss any thing that is deveiating from normal expectation. That’s why Six Sigma experts say “Devation Is Evil”.
