What is Six Sigma?

Six Sigma is a highly disciplined process that helps us focus on developing and delivering near-perfect products and services.
Why "Sigma"? The word is a statistical term that measures how far a given process deviates from perfection. 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.

What are the Key Concepts of Six Sigma ?

At its core, 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.

Why our Customers Feel the Variance, Not the Mean ?

Often, our inside-out view of the business is based on average or mean-based measures of our recent past.
Customers don't judge us on averages, they feel the variance in each transaction, each product we ship. Six Sigma focuses first on reducing process variation and then on improving the process capability.
Customers value consistent, predictable business processes that deliver world-class levels of quality. This is what Six Sigma strives to produce.
