Lean Six Sigma Green Belt
The Lean Six Sigma Green Belt is the practitioner-level certification for professionals who are ready to lead improvement projects, apply statistical analysis tools, and drive meaningful, measurable change in their organization. Green Belts work on real projects — identifying root causes, analyzing data, and implementing solutions that reduce waste, defects, and cycle time.
UNF’s Green Belt program provides you with a comprehensive toolkit: from value stream mapping and cause-and-effect analysis to hypothesis testing and control charts. You will learn to think critically about processes, communicate with data, and create a more customer-focused environment in your company or department.
The program is available in two tracks to serve the broadest range of professionals: a General track applicable across all industries, and a Healthcare Organizations track specifically designed for clinical, administrative, and operational professionals working within hospitals, clinics, and healthcare systems.
