The framework

DMAIC (Define-Measure-Analyse-Improve-Control)

DMAIC is the backbone of Six Sigma: Define the problem and project scope; Measure the current process performance; Analyse data to find root causes; Improve by implementing and testing solutions; Control to sustain the gains and prevent regression.

About this course

The White Belt is the entry point to Six Sigma. You will understand the DMAIC methodology, the concept of variation, and how to support improvement projects as a team member — without needing statistical tools.

The project: Identify a Variation Problem
