Six Sigma is a set of techniques, andtools for process improvement. It was developed by Motorola in 1986.
Sir Bill Smith, “ the Father of six sigma” introduce this quality improvement Methodology to Motorola.
Six Sigma is now an enormous 'brand' in the world of corporate development.
Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects.
Six Sigma approach is a collection of managerial and statistical concept and techniques that focuses on reducing variation inprocesses and preventing deficiencies in product.
The concept of Variation states “NO two items will be perfectly identical.”
In a process that has achieved six sigma capability, the variation is small compared to the range of specification limit.
A six sigma process is one in which 99.9999966% ofthe products manufactured are statistically expected to be free of defects (3.4 defects per million).
Six Sigma is a very clever way of branding and packaging many aspects of Total Quality Management (TQM).
