What Is the Lean Six Sigma Yellow Belt Certification?Your Entry into Process Excellence
The Lean Six Sigma Yellow Belt (LSSYB) is an entry-level certification that validates foundational knowledge of process improvement across the five DMAIC phases of Define, Measure, Analyze, Improve and Control. Lean Six Sigma Yellow Belt certification training in San Juan gives professionals across Puerto Rico a recognised first step into quality, continuous improvement and operational excellence. The credential is awarded by the International Association for Six Sigma Certification (IASSC), now part of PeopleCert, and is recognised by employers worldwide. With no prerequisites to sit the exam, it suits front-line staff, quality and operations team members, supervisors and anyone exploring Lean Six Sigma before progressing to Green Belt.
