Quantitative Methods in Process Improvement – DMAIC Framework

At Greece Lean Six Sigma, we fully align our training methodology, certification criteria, and project-based learning practices with the requirements of the international standard ISO 13053, which outlines the use of DMAIC (Define, Measure, Analyze, Improve, Control) as the core methodology for Six Sigma-based process improvement.

This compliance statement covers both parts of the standard:
