Six Sigma Quality - 6 Sigma
**

*The Six Sigma Methodology*
Sigma is a symbol meaning how much deviation exists in a set of data. It is sometimes called a “bell curve.” In statistics, this is called a standard normal distribution, but the idea is the same. In a bell curve, 50% of the values lie above the mean (average) and 50% of the values lie below the mean. In Statistics we take it a step further and delineate certain data points within that timeline

The sigma value is measured against this. The further out from the mean on the time line the greater the sigma. The objective is to get the minimum sigma. To reduce the variance as much as possible.

**The 6 Sigma Proposition**

All to often businesses base their performance on an average and average-based measures of the recent past. However, customers don’t judge businesses on averages; they feel the variance in each and every transaction. Customers value consistent, predictable business processes and products that deliver world-class levels of quality. Six Sigma focuses first on reducing variation and then on improving process capability

A common goal with a Six Sigma program is to minimize variation within all of our critical processes. Examples of key processes include:
Invoicing/Billing customers; New product development; Processing customer orders; Managing human resources (including payroll, holiday applications, etc.); Hiring employees; Budgeting; Paying bills;Evaluating vendors.

Quantitatively, this means working towards Six Sigma quality, or fewer than 3.4 defects per million “opportunities.” An opportunity is defined as a “chance for non-conformance” (or put another way not meeting required specifications). So the business must adjust it’s culture towards accepting a near perfect operation in executing key processes. Such a cultural change will directly contribute towards customer satisfaction and increased productivity.

**WHERE TO OBTAIN SIX SIGMA MATERIALS**

There are a number of information and support resources available. One of the most well known is perhaps The
Six Sigma Management Kit. This includes explanations, presentations, a sigma calculator, guidebooks, tutorials and other materials.
