DMAIC

Six Sigma improvement cycle: Define, Measure, Analyze, Improve, Control.

Definition

Define the problem, goal, and scope (charter, SIPOC, VOC); Measure the current state (baseline, MSA); Analyze root causes (hypothesis tests, fishbone); Improve with solutions (DOE, pilot); Control to sustain gains (control plan, SPC). Tollgate reviews occur between phases.

Example

A team defines a late-shipment problem, measures baseline on-time rate, analyzes causes, pilots a fix, and monitors with a control chart.

Exam tip

Know which tools belong to which phase; control charts are Control phase.
