CORE DEFINITION

A methodology that applies Six Sigma principles to the design of new products/services. Common models include: DMADV process: - D (Define): Define customer needs and project goals - M (Measure): Measure and quantify customer needs (CTQs) - A (Analyze): Analyze design alternatives - D (Design): Detail design of product/service - V (Verify): Verify design performance. IDOV process (another variant): - Identify → Design → Optimize → Validate. Scaffold role: source control.

Design for Six Sigma applies Six Sigma to the "design of new products/services" (rather than improving existing processes, which is DMAIC). Using DMADV or IDOV, quality is built into the design at the source, based on the philosophy of "prevention first, source control."

MINIMUM ACTION

In progress 0/7

Practice this model in one real situation:

(Using DMADV as an example)
D (Define): Define customer needs (quantified as CTQs)
M (Measure): Measure and quantify needs
A (Analyze): Analyze design alternatives
D (Design): Detail design of product/service
V (Verify): Verify design performance.
(IDOV variant: Identify → Design → Optimize → Validate)
