What Is the Lean Six Sigma Yellow Belt Credential?Your First Step into Process Improvement
The Lean Six Sigma Yellow Belt (LSSYB) is an entry-level process improvement certification that validates foundational knowledge of the DMAIC method across all five phases: Define, Measure, Analyse, Improve and Control. It proves you can support real improvement projects and apply core Lean tools alongside Green and Black Belt leaders. The credential is awarded by the International Association for Six Sigma Certification (IASSC), a globally recognised governing body. There are no prerequisites, so it suits front-line staff, team members, supervisors and career changers who are new to process improvement. In Glasgow, where banks, insurers, manufacturers and public services run defect-sensitive, compliance-heavy operations, Yellow Belt literacy is a practical first step into a quality and continuous improvement career. Delivered in live virtual and classroom formats, the training spans 16 hours of instruction with practice questions mapped to the 60-question IASSC exam.
