Let us be very clear that 6 sigma is not a new finding. It was there since the inception of the use of statistical control methods in the industry…. Six sigma is a measure of the non-conformance of a process … be it a manufacturing process or a non-manufacturing process like making sales invoices. Every company works … to reduce cost by adopting various methods. Most powerful amongst [these methods] is a statistical method … for reducing variability … till such time the process becomes … defect free. Such a … process is called 6 sigma. When you reach [6 sigma] … cost of quality is the lowest, reflected in the profits of the company. - Jawadekar

Six Sigma is a problem solving method for continuous improvement . This method focuses on the statistical analysis of data for making decisions for change. As a problem solving methodology it can be applied to almost any situation . - Duckworth
Six Sigma uses statistical analysis to graphically present data so even managers can make intelligent decisions - Mach
Six Sigma is a management methodology that combines a number of the tools and techniques we have always used in "quality initiatives". …this … data-driven approach requires that we … define defects, measure processes, analyze their capability and improve our processes from the shop floor to the back office. … we place appropriate control tools in place to … ensure that savings we have realized continue or increase. The success … lies in the ability to tie project results directly to bottom line savings and/or improved consumer satisfaction . - Johnson
Six Sigma is a customer centered, systematic, data driven method for doing things better
Customer centered means that projects start with, and are measured by, meeting customer wants and needs.
Systematic means that the Six Sigma tools are applied in concert, which makes them vastly more powerful than they are alone.
Data driven means that facts and data are used for making decisions.
Doing things better means, in some measurable, meaningful way, improving the situation of customers, workers, or shareholders of the organization . - Denton Bramwell, Sr. Master Black Belt, firstname.lastname@example.org
Included quality tools and lessons from previous experience
A focus on:
Cycle Time Reduction
Baldridge Quality Award 1988
Quality can be defined as “the value added by a productive endeavor”
Potential (maximum possible value) – Actual (current value)
Where Did Six Sigma Come From? The Motorola Experience “ One of Motorola’s most significant contributions was to change the discussion of quality from one where quality levels were measured in percentages (parts per hundred) to a discussion of parts per million or even parts per billion. Motorola correctly pointed out that … old ideas about acceptable quality levels were no longer acceptable.” Motorola’s Six Sigma Program – Thomas Pyzdek
“ Quality requires us to look … at our processes from the outside-in. By understanding the transaction lifecycle from the customer’s needs & processes, we can discover what they are seeing and feeling. With this knowledge… we can add significant value or improvement from their perspective.”
“ Customers … define Quality. They expect performance, reliability, competitive prices, on-time delivery, service, clear & correct transaction processing & more. … being good is not enough. Delighting our customers is a necessity. Because if we don’t do it, someone else will !” - GE Six Sigma
“ The central idea behind Six Sigma is that if you can measure how many “defects” you have in a process, you can systematically figure out how to eliminate them and get as close to “zero defects” as possible.” - GE Six Sigma
Customer Focus – Integrate the customer into the organization. Listen to them!
Data Driven – Critical to Quality (CTQ), Defects, Pareto Charts, Root Cause Analysis, Process Mapping, Control Charts, Statistical Process Control, Gage R&R, Brainstorming, FMEA (Failure Mode Effect Analysis), Design of Experiments
Robust Methodology – (1) DMAIC (Define, Measure, Analyze, Improve, Control) - Continued improvement on existing processes. (2) DMADV (Define, Measure, Analyze, Design, Verify) – New product or processes.

Black Belt or Black Magic? “ Six Sigma’s magic isn’t in statistical or high-tech razzle-dazzle. Six Sigma relies on tried and true methods that have been around for decades. In fact, Six Sigma discards a great deal of the complexity that characterized Total Quality Management (TQM). By one expert’s count, there were over 400 TQM tools and techniques. Six Sigma takes a handful of proven methods … the tools are applied within a simple performance improvement model known as DMAIC.” Six Sigma Revolution Thomas Pyzdek

“ Experts who can “work out the details” are a dime-a-dozen. Hire a full-time person or rent a consultant.” - Doug Welter
Is That All There Is? “ Some people, including me, believe that garden variety six sigma doesn't go far enough. In fact, even zero defects falls short. … Progressive people in the six sigma camp … looks for critical-to-quality (CTQ) characteristics in a product or service. CTQ features are those that customers expect and consider explicitly … A product or service that doesn't provide the CTQ features that customers expect suffers lower customer satisfaction. But even this definition isn't enough. ” Six Sigma and Beyond Thomas Pyzdek
Where To From Here? “ Long-term success requires the customer to be excited by unexpected innovations provided by a company's products and services: Continued survival requires that your organization continuously innovate. Innovation is the result of creative activity, not of analysis. Creativity can't be achieved "by the numbers." In fact, excessive attention to a rigorous process such as six sigma actually detracts from creativity.” Six Sigma and Beyond Thomas Pyzdek
