DMAIC vs. DMADV — What's the Difference?
By Tayyaba Rehman — Published on December 27, 2023
DMAIC (Define, Measure, Analyze, Improve, Control) is a systematic approach for improving existing processes, while DMADV (Define, Measure, Analyze, Design, Verify) focuses on creating new processes or products.

Key Differences
Both DMAIC and DMADV are methodologies used within Six Sigma, a set of techniques aimed at improving processes and ensuring quality. They share the initial three phases (Define, Measure, Analyze) but diverge in their latter stages.
DMAIC, standing for Define, Measure, Analyze, Improve, Control, is geared towards refining existing processes. The aim here is to enhance efficiency and reduce defects in an ongoing operation. DMADV, on the other hand, consists of Define, Measure, Analyze, Design, and Verify. This methodology prioritizes designing new processes or products.
The Improve phase of DMAIC is where the process's performance is optimized to meet the desired improvements. This contrasts with DMADV's Design phase, where a new process or product design is created based on the analyzed data.
In DMAIC's Control phase, the improvements made in the previous step are sustained and monitored to ensure long-term success. DMADV's Verify phase ensures the designed process or product meets specified performance levels and requires rigorous testing.
In essence, while both DMAIC and DMADV serve vital roles in Six Sigma, DMAIC refines and perfects existing processes, and DMADV lays the foundation for new, efficient processes or products.
