What is the difference between Yellow and Green Belt training?

Green Belt training goes beyond basic awareness to equip you with advanced analytical skills and the ability to lead improvement projects independently.

Will I learn statistical tools in the Green Belt course?

Yes, the course includes training on calculating process performance metrics like DPMO and Sigma levels to make data-driven decisions.

Can I use SimplicityHub templates during my project?

Absolutely, the Green Belt curriculum integrates practical templates like the Value Stream Map and RACI Matrix to help manage your projects successfully.

Course Content

✓ Advanced project management for DMAIC: multi-workstream projects, stakeholder management, and change control

✓ Advanced process capability: Cp, Cpk, Pp, Ppk, and interpreting capability indices for customer specifications

✓ Intermediate statistics: normality testing, confidence intervals, and selecting the right statistical test

✓ Hypothesis testing in depth: t-tests, ANOVA, chi-square, Mann-Whitney, and when to use each

✓ Regression analysis: simple and multiple linear regression, residual analysis, and prediction intervals

✓ Design of Experiments (DOE) introduction: full factorial designs, main effects, and interaction plots

✓ FMEA (Failure Mode and Effects Analysis): risk prioritisation for process and product design

✓ Multi-vari charts, box plots, and graphical analysis for root cause confirmation

✓ Advanced control charts: Xbar-R, Xbar-S, I-MR, P-charts, C-charts — selection criteria and interpretation

✓ Project financials: calculating hard and soft savings, benefit realisation, and presenting ROI to finance teams

Learning Outcomes

✓ Lead a full Green Belt DMAIC project involving statistical analysis and data-driven root cause confirmation

✓ Perform and interpret process capability analysis for any continuous or attribute data set

✓ Select and run the correct hypothesis test to confirm or reject improvement hypotheses

✓ Use regression analysis to model relationships between process inputs and outputs

✓ Design and analyse a basic factorial experiment to optimise process settings

✓ Complete an FMEA for a process redesign and use RPN scores to prioritise risk mitigation

✓ Build and interpret a suite of control charts for ongoing process monitoring

✓ Present a completed project to a finance team with a validated savings calculation

Estimated Annual Time Saving per Person

Estimated 20–50 hours per person per year. Green Belt projects typically deliver 20–40% reduction in defect rates, 15–35% improvement in cycle time, and measurable cost of quality savings. A single well-executed Green Belt project commonly saves £50,000–£250,000 in direct costs per year, depending on process volume.
