Six Sigma in Project Management: DMAIC Explained

Quick answer

Six Sigma reduces defects with DMAIC — Define, Measure, Analyze, Improve, Control — a data-driven discipline for processes that must be right nearly every time.

DMAIC

Define the problem → Measure the current process → Analyze causes → Improve → Control the gain — a rigorous cycle.

The tools

Process maps, capability stats, control charts, FMEA — statistics applied to process quality.

For PMs

Six Sigma projects are run like projects — the DMAIC phases are a project plan in disguise.

When it fits

Repetitive processes with measurable defects — not discovery work or one-offs.

Bottom line

Six Sigma reduces defects with DMAIC — Define, Measure, Analyze, Improve, Control — a data-driven discipline for processes that must be right nearly every time.
