Transcript of Six Sigma

Six Sigma helps reduce defects, decrease costs and improve performance

Origin of 6 Sigma
Today, without 6 Sigma,
life would be not as good
Practical meaning
& implications

How to improve the process output by moving the mean?
Greek letter

"Statistical measurement of the variability" or

"Spread of data"

A set of techniques and tools for process improvement across areas

Term comes from statistics and is used in statistical quality control,
which evaluates process capability

The higher the sigma, the fewer the defects, the better the performance.

Statistical modeling of manufacturing processes - A six sigma process is one in which
99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects
(3.4 defective features / million opportunities)

The level of six sigma represents a near flawless process (3.4 defects per million opportunities). Most organizations operate at 3 to 4 Sigma

Today over two-thirds of the Fortune 500
organizations use Six Sigma initiatives with the aim of reducing costs and improving quality
By reducing the process output variation

Since then, evolved not only as a
variation management tool
but as -
"a new performance excellence methodology and a strategic culture change tool."

Used to measure how well a process or product meets customers requirements.

Seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors)

Minimizing variability in manufacturing and business processes across the entire business operations

Used by Ford, Toyota, Apple, IBM and today by the entire manufacturing world in addition to other industries, sectors and businesses
" Six Sigma helped GE save over
US $ 2 Billion over 3 years."

" It is in the "Bones" of GE
Management and a crucial
