DMAIC – Define, Measure Analyze, Improve, Control
A business management approach and a fundamental component of the Six Sigma business philosophy. DMAIC is a five-step method for ensuring that products or processes adhere to Six Sigma quality levels (i.e., no more than 3.4 defects per million opportunities), generally by improving processes:
1) Define (objectives and deliverables, both internal and external);
2) Measure (current performance);
3) Analyze (defects and their root causes);
4) Improve (elimination of existing defects); and
5) Control (future performance of the process).
