What Is the Lean Six Sigma Yellow Belt Certification?UntitledYour First Step into Process Improvement
The Lean Six Sigma Yellow Belt (LSSYB) is an entry-level certification that validates your foundational knowledge of process improvement across the five DMAIC phases: Define, Measure, Analyse, Improve and Control. Awarded by the International Association for Six Sigma Certification (IASSC), it confirms you can support improvement teams and apply core Lean and Six Sigma tools in any sector. In Switzerland, where pharmaceutical, manufacturing, banking and food companies compete on quality and efficiency, a recognised Lean Six Sigma credential marks you out as someone who can reduce waste, cut defects and improve everyday processes. The Yellow Belt is the ideal first step for professionals who are new to continuous improvement. This IASSC-aligned programme prepares you for the 60-question ICYB exam while building practical skills you can use at work from day one. Begin your continuous improvement journey with Invensis Learning and build a foundation you can grow into Green and Black Belt levels.
