    The Lean Six Sigma Skills You Will MasterAcross the Five DMAIC Phases

    This Green Belt programme builds practical, job-ready process improvement skills mapped to the IASSC Body of Knowledge. By the end, you can run a full DMAIC project, apply Lean and statistical tools, and sustain measurable improvements at work.

    Define Projects That Matter

    Learn how to scope improvement projects that deliver value. You will build a business case and project charter, capture the Voice of the Customer, identify Critical to Quality characteristics, and set the metrics that prove success.

    Measure Process Performance

    Map processes with SIPOC and value stream maps, establish baseline metrics such as DPMO, FTY and RTY, run measurement system analysis, and assess process capability so you know where a process stands today.

    Analyse Root Causes with Data

    Use descriptive and inferential statistics, graphical analysis and hypothesis testing to separate real causes from noise, so improvement decisions rest on evidence rather than opinion.

    Improve Processes and Cut Waste

    Apply regression, designed experiments and Lean tools such as 5S, Kanban and value stream mapping to remove waste, reduce variation and deliver measurable gains in cost, quality and speed.

    Control and Sustain the Gains

    Hold improvements in place with statistical process control charts, Poka-Yoke mistake-proofing and control plans, so the savings you deliver do not slip back over time.

    Run an End-To-End DMAIC Project

    Bring the full Define, Measure, Analyse, Improve and Control framework together on a real or simulated workplace problem, and build the exam readiness you need to pass the Green Belt certification.
