Lean Six Sigma
A complete belt path in one library. Yellow Belt for awareness and team participation, Green Belt for running improvement projects, Black Belt for leading them and coaching others. Each tier reuses the DMAIC structure at increasing statistical depth.
What it covers
Yellow Belt — foundations
Lean and Six Sigma history, DMAIC overview, waste, basic process mapping, and how to contribute to a project team.
Green Belt — Define
Project charter, SIPOC, voice of the customer, critical-to-quality translation, and scoping a problem to a solvable size.
Green Belt — Measure
Data collection planning, operational definitions, measurement system analysis, baseline capability, and process capability indices.
Green Belt — Analyse
Graphical analysis, hypothesis testing, correlation and regression, and root cause validation with data.
Green Belt — Improve
Solution generation, pilots, mistake-proofing, and basic design of experiments.
Green Belt — Control
Control plans, control charts, standard work, and formal handover to the process owner.
Black Belt — advanced methods
Advanced DOE, non-normal data, multivariate analysis, reliability, and modelling.
Black Belt — leading and coaching
Project selection and portfolio of improvements, mentoring Green Belts, change leadership, and financial validation of benefits.
Exam preparation
Practice questions, worked case studies, and a formula and terminology reference for each tier.
Who it's for
Anyone from team members joining their first improvement project to full-time improvement specialists and their managers.

- Test a root cause hypothesis statistically and interpret the result honestly
- Build a control plan that holds the gain after handover
Belt tiers are taught in sequence; the Green and Black Belt tiers assume the preceding material. Certification is offered by external awarding bodies — these materials prepare candidates but do not themselves certify.
