DMAIC (Design, Measure, Analyze, Improve, Control) must be used to give Six Sigma projects the go ahead and prompt early enthusiasm and success.
Design for Six Sigma (DFSS) and Define Measure Analyze Design Verify (DMADV) must be used when a total revamp or restructuring is required for a failed or nonexistent process. DFSS and DMADV are best for future state designs without considering what is happening today.
