Six Sigma Definition
Six
Sigma is a long-term, forward-thinking initiative designed to
fundamentally change the way corporations do business. It is first
and foremost "a business process that enables companies to
increase profits dramatically by streamlining operations,
improving quality, and eliminating defects or mistakes in
everything a company does. While traditional quality programs have
focused on detecting and correcting defects, Six Sigma encompasses
something broader: It provides specific methods to re-create the
process itself so that defects are never produced in the first
place"
-
Six
Sigma provides the techniques and tools to improve the
capability and reduce the defects in any business process.
-
Six
Sigma is a methodology used to improve any existing business
process by constantly reviewing and re-tuning the process. To
achieve this, Six Sigma uses a methodology known as DMAIC
(Define opportunities, Measure performance, Analyze
opportunity, Improve performance, Control performance).
-
Six
Sigma methodology can also be used to create a brand new
business process using DFSS (Design For Six Sigma) principles.
-
Six
Sigma Strives for perfection. It allows for only 3.4 defects
per million opportunities for each product or service
transaction.
-
Six
Sigma relies heavily on statistical techniques to reduce
defects and measure quality.
-
Six
Sigma experts evaluate a business process and determine ways
to improve upon the existing process.
-
Six
Sigma experts can also design a brand new business process
using DFSS (Design For Six Sigma) principles. Typically its
easier to define a new process with DFSS principles than
refining an existing process to reduce the defects. Six Sigma
incorporates the basic principles and techniques used in
Business, Statistics, and Engineering.
-
Six
Sigma improves the process performance, decreases variation
and maintains consistent quality of the process output. This
leads to defect reduction and improvement in profits, product
quality and customer satisfaction.
