Six Sigma Strategy
Strategy of improvements through Six Sigma can be summed up as any one or combination of the following 3 S.
SHIFT: If the central tendency of the process is outside the specification limits and spread is well within these limits, we need to Shift the process within these limits.
SHRINK: If the central tendency of the process is within the limits but the spread of the process is beyond the limits, Shrink the process within the limits
Stabilise: If both central tendency and spread are as desired, stabilise the process by monitoring, standardizing and documenting the process.
To achieve Six Sigma quality, a process must produce no more than 3.4 defects per million opportunities. An "opportunity" is defined as a chance for nonconformance, or not meeting the required specifications. This means we need to be nearly flawless in executing our key processes. Six Sigma is a vision we strive toward and a philosophy that is part of our business culture.

Six Sigma at many organizations simply means a measure of quality that strives for near perfection. Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process -- from manufacturing to transactional and from product to service.
The statistical representation of Six Sigma describes quantitatively how a process is performing. To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. A Six Sigma defect is defined as anything outside of customer specifications. A Six Sigma opportunity is then the total quantity of chances for a defect. Process sigma can easily be calculated using a Six Sigma calculator.
The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation reduction through the application of Six Sigma improvement projects. This is accomplished through the use of two Six Sigma sub-methodologies: DMAIC and DMADV. The Six Sigma DMAIC process (define, measure, analyze, improve, control) is an improvement system for existing processes falling below specification and looking for incremental improvement. The Six Sigma DMADV process (define, measure, analyze, design, verify) is an improvement system used to develop new processes or products at Six Sigma quality levels. It can also be employed if a current process requires more than just incremental improvement. Both Six Sigma processes are executed by Six Sigma Green Belts and Six Sigma Black Belts, and are overseen by Six Sigma Master Black Belts.
According to the Six Sigma Academy, Black Belts save companies approximately $230,000 per project and can complete four to 6 projects per year. General Electric, one of the most successful companies implementing Six Sigma, has estimated benefits on the order of $10 billion during the first five years of implementation. GE first began Six Sigma in 1995 after Motorola and Allied Signal blazed the Six Sigma trail. Since then, thousands of companies around the world have discovered the far reaching benefits of Six Sigma.

Six Sigma is a quality achievement strategy often applied to manufacturing. It has been used by Lucent, Motorola, and other tech companies.

You can use Six Sigma tools for building and testing strategic plans.
You would use the Cause & Effects Matrix to identify the critical aspects of your plan, and the Faliture Modes & Effects Analysis to explore what could go wrong, and how to put it right.
We call this strategic "bullet-proofing".

6 sigma is a Standardization/Perfaction in quality of a Product or quality achivement (where the 66% accuracy in the finished goods & remaining 33% error).
ex. 6 sigma users: motorola
The Co. "Aviation" uses the 9 sigma thus here we can say near about ZERO-ERRORS.
