Two Six Sigma sub-methodologies are called:
DMAIC - Define, Measure, Analyze, Improve and Control, and
DMADV - Define, Measure, Analyze, Design, Verify.
They are both systematic, structured and fact-based methodologies, rather than relying on gut feeling or expert opinions.
DMAIC is an improvement system for EXISTING processes which fall below SPECIFICATIONS and need to be improved incrementally.
DMADV is also an improvement system which is designed to develop NEW processes and/ or products at Six Sigma quality levels. DMADV is typically used when a CLIENT or customer requires product improvement, adjustment, or the creation of an entirely new product or service.
