The Lean Six Sigma Green Belt is the most impactful entry-level professional certification in quality and process improvement. It gives you the tools, the methodology, and the project experience to lead real improvement initiatives — reducing defects, cutting waste, and delivering measurable savings for your organisation. At ICEQBS, every Green Belt student is trained directly by C. Annamalai — Master Black Belt from ISI Chennai, ASQ Black Belt, IIT-BHU engineer, and a practitioner who has led 500+ Lean Six Sigma projects across manufacturing, healthcare, IT, logistics, and financial services over 42 years. When Annamalai sir teaches DMAIC, he is not reading from a slide — he is drawing from five decades of real project leadership.
