An Introduction to Six Sigma Methodology



Objective of the this brief Orientation is to prepare associates, leaders, managers to drive & support Six Sigma

Six Sigma – a Term often heard of or mentioned by so many- but used by only a few, is a simple yet accurate way of rendering Quality products, and services to our customers. I have tried to bring out the basic idea of Six Sigma in the abstract I have created, however, it is only mutual interaction and understanding of this methodology with respect to our process that will help us achieve better results.

Definition Of Six Sigma.

What Is Six Sigma?

Six Sigma stands for Six Standard Deviations (Sigma is the Greek letter used to represent standard deviation in statistics from mean, as seen above) Six Sigma methodology provides the techniques and tools to improve the capability and reduce the defects in any process.

It was started in Motorola, in its manufacturing division, in 1979 where millions of parts are made using the same process repeatedly. Eventually Six Sigma evolved and applied to other non-manufacturing processes.

In Six Sigma we say that quality is a state in which value entitlement is realized for the customer and the provider in every aspect of the business relationship

Today you can apply Six Sigma to many fields such as Services, Medical and Insurance Procedures, Call Centers. The Bottom line is that the Organization should be a Learning Organization

Six Sigma methodology improves any existing business process by constantly reviewing and re-tuning the process. Six Sigma has a Long Term Outlook, & to achieve this, Six Sigma uses a methodology known as DMAIC (Define opportunities, Measure performance, Analyze opportunity, Improve performance, Control performance).

The Six Sigma methodology can also be used to create a brand new business process from ground up using DFSS (Design For Six Sigma) principles. Six Sigma Methodology aims for perfection. It allows for only 3.4 defects per million opportunities (DPMO) for each product or service transaction. Six Sigma relies heavily on statistical techniques to reduce defects and measure quality. It’s important to understand that Six Sigma is a performance target or methodology that applies to a single Critical-to-Quality (CTQ) Characteristic, not to the Total Product.
