The proliferation of Lean & Six Sigma continues to expand worldwide to every type of organization. Experienced practitioners and belts continue to be in high demand, with ever-growing number of professionals identifying themselves with the title “Six Sigma Green Belt” (over half a million on LinkedIn alone at the time of publication). With this rapid growth, better and more consistent applications of Lean, Six Sigma, and other improvement principles will enhance organizational performance, individual competency, public good, and above all, customer satisfaction.

The main challenge in the creation of a Green Belt Training Standard is to balance two contradictory states: standards that reduce variation and meet minimum performance baselines, but also provide the freedom and flexibility to adapt Lean & Six Sigma to specific situations and evolving practices – our goal and much of our focus was to strike this balance. However, as this is a draft version, we welcome any and all feedback through our online form.
