What Is the Lean Six Sigma Yellow Belt Certification?Your Entry into Process Improvement
The Lean Six Sigma Yellow Belt (LSSYB) is an entry-level process improvement credential that validates your understanding of the DMAIC method and core Lean tools. Awarded through the International Association for Six Sigma Certification (IASSC), it confirms you can support improvement projects as an informed team member and carries the IASSC-CYB designation. For professionals in Nanjing, where integrated circuits, new-energy vehicles and smart manufacturing drive the local economy, the Yellow Belt is a practical first step into quality and operational excellence. You learn to define problems, measure process performance, analyse variation and support improvements that reduce defects and waste. The course suits front-line staff, quality team members, supervisors and anyone new to Six Sigma. It builds a recognised foundation you can carry into Green Belt study later.
