    Skills You Will Build Across the DMAIC CycleThe Full DMAIC Toolkit

    The Green Belt programme builds practical, data-driven capability across all five DMAIC phases. By the end, you can scope an improvement project, baseline a process, find root causes, implement verified solutions and sustain the gains. Skills covered in Lean Six Sigma Green Belt training map directly to the IASSC Green Belt Body of Knowledge.

    Scope and Charter Improvement Projects

    Define problems using Voice of the Customer, critical-to-quality characteristics, cost of poor quality and a clear project charter, so every improvement starts with a measurable business case.

    Measure Processes and Baseline Performance

    Map processes with SIPOC and value stream maps, run measurement system analysis, and use core Six Sigma metrics and process capability to establish a reliable performance baseline.

    Analyse Data to Find Root Causes

    Apply descriptive and inferential statistics, hypothesis testing, ANOVA and regression to separate real causes of variation from noise and pinpoint what truly drives defects.

    Improve Processes with Data-Backed Solutions

    Use simple and multiple regression and designed experiments to test changes, model relationships and select solutions that deliver verifiable improvement, not guesswork.

    Sustain Gains with Statistical Process Control

    Build control plans and read control charts such as I-MR, Xbar-R and P charts to monitor processes and hold improvements in place long after the project ends.

    Apply Lean Tools to Eliminate Waste

    Put 5S, Kanban, Poka-Yoke and waste-reduction principles to work within the DMAIC cycle to remove non-value-adding steps and speed up everyday operations.
