What is Six Sigma
A process improvement methodology created by Mikel Harry and Richard
Schroeder at Motorola in the early 1980's. It is a method or set
of techniques for quality measurement and improvement program
originally developed by Motorola that focuses on the control of a
process to the extent of 3.4 defects per million items. A Six Sigma
systematic quality program provides businesses with the tools to
improve the capability of their business processes. It includes
identifying factors critical to quality as determined by the customer,
reducing process variation and improving capabilities, increasing
stability and designing systems to support the six sigma goal.
Six Sigma is a business system for achieving and sustaining success
through customer focus, process management and improvement and the wise
use of facts and data.
Unlike the other quality programs, Six sigma is not a goal but a means
by which the goals of quality improvement and cost reduction are
achieved. Six Sigma gives relentless attention to the “Voice of
customer” and measurement techniques employed in the process.
This helps the top management of an organization to develop a fact and
data driven attitude.
Why do Companies Need it
Generally speaking, companies use Six Sigma to reduce variation in
products and processes - but the net effect of any Six Sigma project is
what people are really looking for: fewer defects, shorter cycle times,
increased capacity and throughput, lower costs, higher revenues and
reduced capital expenditures. When Six Sigma is deployed systematically
and pervasively - with the right technology support and leadership
force - it can produce large amounts of cash for shorter-term
profitability or for longer-term investments. In its most simple sense,
Six Sigma is a highly disciplined approach to decision making that
helps people focus on improving processes to make them as near perfect
