    Skills You Will Master Across the DMAIC CycleApplied Tools for Real Improvement Projects

    This Black Belt programme builds advanced, hands-on capability across all five phases of DMAIC. By the end, you can lead complex, data-driven improvement projects and prepare with confidence for the IASSC-aligned Black Belt exam.

    Define and Scope Improvement Projects

    Skills covered in Lean Six Sigma Black Belt training start with the Define phase. Build business cases and project charters, capture the voice of the customer, and translate vague problems into measurable improvement goals using the Y equals f of x strategy.

    Measure Processes with Data

    Apply process mapping, SIPOC and FMEA, calculate Six Sigma metrics such as DPMO and rolled throughput yield, and run measurement system analysis and process capability studies to establish a reliable performance baseline.

    Analyse Root Causes Statistically

    Use inferential statistics, the central limit theorem and hypothesis testing with normal and non-normal data, including t-tests, ANOVA and chi-squared, to separate real causes from noise and prove what actually drives variation.

    Improve with Regression and DoE

    Model relationships using simple and multiple regression, then design and interpret full and fractional factorial experiments to optimise process settings and confirm which changes deliver measurable improvement.

    Control and Sustain Gains

    Hold improvements in place with statistical process control, building I-MR, Xbar-R, P and other control charts, and embed Lean controls such as 5S, Kanban and Poka-Yoke within a structured control plan.

    Apply Lean Tools and Lead Projects

    Integrate Lean waste elimination, value stream mapping and the seven elements of waste within DMAIC, and develop the leadership skill to run complex projects full-time and mentor Green Belt teams.
