CORE DEFINITION

The core framework of the Six Sigma improvement methodology, used to improve existing processes. It consists of five phases: - D (Define): Define - clarify the problem, objectives, scope, and customer requirements; - M (Measure): Measure - collect data, establish a baseline, and quantify current performance; - A (Analyze): Analyze - identify root causes and verify causal relationships; - I (Improve): Improve - develop, test, and implement solutions; - C (Control): Control - establish control mechanisms to sustain improvements.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Data-driven, systematic improvement. DMAIC emphasizes "no measurement, no improvement," identifying root causes through rigorous data analysis rather than intuition.
