DMAIC is a structured, data‑driven improvement methodology widely used in Lean Six Sigma to enhance processes and solve complex problems.

The acronym stands for Define, Measure, Analyze, Improve, and Control, representing a clear, step‑by‑step approach that helps teams move from identifying an issue to embedding long‑term solutions. By combining disciplined problem‑solving with robust data analysis, DMAIC enables organisations to reduce variation, eliminate waste, and deliver more consistent, high‑quality outcomes.
