    The Lean Six Sigma Skills You Will BuildHands-On DMAIC Capability

    Skills covered in Lean Six Sigma Green Belt training span the full DMAIC method, from defining and measuring processes to analysing data, improving performance and sustaining control. By the end, you can lead scoped improvement projects that deliver real results.

    Define and Scope Improvement Projects

    You will learn to frame the right problems using project charters, voice of the customer, CTQs and the cost of poor quality, then build a business case that links improvement to real organisational value.

    Measure Processes with Data

    Map processes with SIPOC and value stream maps, build cause-and-effect and FMEA analyses, and apply measurement system analysis and process capability so your baseline data is accurate and trusted.

    Analyse Root Causes Statistically

    Use descriptive and inferential statistics, sampling and hypothesis testing for normal and non-normal data to separate real causes from noise and pinpoint what truly drives process variation.

    Improve with Tested Solutions

    Apply simple and multiple regression and designed experiments, including full factorial methods, to model relationships, test changes and select solutions that deliver measurable, repeatable gains.

    Control and Sustain the Gains

    Build statistical process control charts, control plans and response plans, and use Lean controls such as Kanban and Poka-Yoke so improvements hold long after the project closes.

    Apply Lean Tools to Cut Waste

    Put 5S, value stream mapping, the seven wastes and mistake-proofing to work, integrating Lean thinking within the DMAIC framework to remove delay and cost from everyday operations.
