Six Sigma – The Basics

Six Sigma is the systematic practice of improving processes by eliminating defects. Its basic precepts are:

1. Reduction in variation process outputs is the key to business success
2. Business processes can be measured, analyzed, improved and controlled
3. Achieving sustained quality improvement requires commitment from the entire organization, particularly from upper-level management

This is a business paradigm that uses objective measurement and observation, and is worth the considerable effort it takes to fully investigate and deploy.
