Six Sigma




Six Sigma

Six Sigma was initially defined as a metric for measuring defects and improving quality (plus a method to reduce defect levels). It was produced in the mid-eighties by Motorola Inc, but was quickly taken on by a number of very large very high profile corporations.

Six Sigma actually comprises 2 methods:
DMAIC, which is used to improve an existing business process.
DMADV, which is used to create new product designs or process designs wuch that it results in a more predictable and defect free performance.

DMAIC's five phases are: Define, Measure, Analyze, Improve and Control. DMADV's are Define, Measure, Analyze, Design, Verify.
