ICTQual AB Level 3 Diploma in Lean Six Sigma – Green Belt
The Level 3 Diploma in Lean Six Sigma – Green Belt is designed to develop practical and analytical knowledge of process improvement, quality management and operational excellence. It enables Learners to understand how structured Lean Six Sigma methodologies can be applied to analyse processes, identify root causes, reduce waste and variation, improve quality and achieve measurable performance improvements.
The course explores important areas including Lean principles, Six Sigma methodology, process mapping, data collection, process measurement, statistical thinking, waste reduction, root cause analysis, defect prevention and continuous improvement. Learners develop the ability to examine workplace processes systematically, interpret relevant information and contribute to improvement projects using recognised Lean Six Sigma concepts and techniques.
The Level 3 Diploma in Lean Six Sigma – Green Belt is suitable for Learners working or intending to work in quality, operations, manufacturing, engineering, logistics, construction, healthcare and service-based environments. It can also support professionals who are involved in operational performance, quality improvement or process optimisation.
Through practical, evidence-based learning, the qualification helps Learners develop the knowledge and problem-solving capability required to support structured improvement initiatives, improve process efficiency and contribute to sustainable quality and performance improvements across diverse organisational environments.
