Some manufacturing problems need refinement. Others need a complete rethink. 👈 👉

In automotive manufacturing, improving performance starts with understanding what actually needs to change. Is an established process falling short, or does the challenge call for a different solution altogether?

That's where DMAIC and DMADV come in. Both are structured, data-driven Six Sigma methodologies, but each follows a different path.

DMAIC focuses on improving an existing process. Its five phases help teams identify what's going wrong, understand why, and make improvements that last.

Define the problem and objectives. Measure current performance. Analyze the root causes. Improve the process by addressing those causes. Control the results to sustain the gains.

DMADV is used when developing a new product or process, or when an existing solution needs a fundamental redesign.

It also starts with Define, Measure, and Analyze, with greater emphasis on customer requirements and design options. Then comes Design, to develop the new solution, and Verify, to confirm it meets those requirements.

The difference matters on the shop floor. A recurring defect or unstable cycle may call for DMAIC. A production concept that can't meet its requirements through incremental changes may need DMADV.

At ADIS Tachov s.r.o., we know that good improvement work starts with the right questions. Sometimes the best answer is to fine-tune what's already working. Sometimes it's to rethink the approach from the ground up.
