DMADV ⚑
Six Sigma design cycle: Define, Measure, Analyze, Design, Verify.
DMADV is the Six Sigma design-for-quality cycle used when no existing process exists to improve, or when a process requires fundamental redesign rather than incremental improvement — also known as Design for Six Sigma (DFSS). Define establishes goals consistent with customer demands and enterprise strategy. Measure and identify CTQs (Critical to Quality characteristics), product capabilities, production process capability, and risks. Analyze develops and designs alternatives at the high level. Design develops detailed designs, often using QFD (Quality Function Deployment), DOE (Design of Experiments), and Pugh-style concept selection, with pilots simulating the design. Verify the design, run pilot runs, and hand over to process owners. DMADV emerged in the late 1990s as Six Sigma extended from improving existing processes (DMAIC's domain) to greenfield design, and is closely related to Stage-Gate practices in product development. Multiple alternative DFSS roadmaps exist (IDOV, DMEDI), with DMADV the most widely cited.
Core components
- Define (goals consistent with customer demands, enterprise strategy)
- Measure (customer needs, CTQs — Critical to Quality characteristics)
- Analyze (process options, alternative designs)
- Design (detailed design with QFD, DOE, Pugh selection)
- Verify (pilot, validate, hand over)
- Connection to QFD and Pugh Matrix
- DFSS umbrella with IDOV and DMEDI alternatives
Primary use case
Greenfield design of new products, services, or processes within Six Sigma programs; situations where DMAIC's incremental-improvement frame doesn't fit; design-for-quality initiatives in product development; complement to Stage-Gate in regulated industries.
Common criticisms
- Less established and less widely-adopted than DMAIC, with corresponding implementation variability
- substantial overlap with general product-development frameworks (Stage-Gate) creates uncertainty about which to use
- can be heavyweight for smaller design problems
- relies on customer-needs research rigor that organizations often lack
- limited empirical evidence on incremental value over disciplined product development without DFSS branding
- commercial certification industry around DFSS limits independent assessment
- tension between Six Sigma's quality orientation and innovation's exploratory needs.
