What is DMADV or DFSS

The DMADV project methodology, known as DFSS (Design For Six Sigma), features five phases:

Define design goals that are consistent with customer demands and the enterprise strategy.
Measure and identify CTQs (characteristics that are Critical To Quality), product capabilities, production process capability, and risks.
Analyze to develop and design alternatives, create a high-level design and evaluate design capability to select the best design.
Design details, optimize the design, and plan for design verification. This phase may require simulations
Verify the design, set up pilot runs, implement the production process and hand it over to the process owner(s).
