 CSE Software Inc. has
begun the formal process to train in the Six Sigma methodology. We are dedicated
to using this process to further improve our products and services to our customer.
Below is a brief history and explanation of Six Sigma.
Six Sigma is a system of practices originally developed by Motorola to systematically improve processes by eliminating defects.1
Defects are defined as units that are not members of the intended population. Since it was originally developed, Six Sigma has become an element of many Total Quality Management (TQM) initiatives.
The process was pioneered by Bill Smith at Motorola in 1986
2 and was originally defined 3
as a metric for measuring defects and improving quality, and a methodology to reduce defect levels below 3.4 Defects Per (one) Million Opportunities (DPMO).
Six Sigma is a registered service mark and trademark of Motorola, Inc.4
Motorola has reported over US$17 billion in savings5
from Six Sigma as of 2006.
In addition to Motorola, companies which also adopted Six Sigma methodologies early-on and continue to practice it today include Bank of America, Caterpillar, Honeywell International (previously known as Allied Signal), Raytheon and General Electric (introduced by Jack Welch).
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
Design for Six Sigma: Designing to meet customer needs and process capability
The term Six Sigma
Sigma (the lower-case Greek letter σ) is used to represent standard deviation (a
measure of variation) of a population (lower-case 's', is an estimate, based on
a sample). The term "six sigma process" comes from the notion that if one has six
standard deviations between the mean of a process and the nearest specification
limit, he will make practically no items that exceed the specifications. This is
the basis of the Process Capability Study, often used by quality professionals.
The term "Six Sigma" has its roots in this tool, rather than in simple process standard
deviation, which is also measured in sigmas.
