This is an eight-week IASSC Lean Six Sigma Green Belt plan that builds phase by phase through DMAIC. It puts extra time into the statistics in Measure and Analyze, where most marks are lost. Stretch the statistics weeks if you are new to them. Confirm the current body of knowledge on the IASSC certification page.
Week 1 - Define
Project selection, voice of the customer and CTQs, problem statements and project charters. Learn how an improvement project is framed.
Weeks 2-3 - Measure
Process mapping, data types, measurement-system analysis, basic statistics and process capability. The statistics begin here, so go slowly and practise.
Weeks 4-5 - Analyze
Root-cause analysis, hypothesis testing, correlation and the basics of regression. This is the other statistics-heavy phase.
Week 6 - Improve and Control
Generating, piloting and implementing improvements; then control plans and statistical process control (SPC) to sustain the gains.
Weeks 7-8 - Practice and review
Sit full-length, timed practice exams against the body of knowledge. Review the reasoning behind every miss, focus on Measure and Analyze, and aim to score comfortably above 70% on fresh questions.
Tips
- Learn each tool by its DMAIC phase, not in isolation.
- Do not skip the statistics - they are where most candidates lose marks.
- Confirm you are studying the IASSC body of knowledge, not another body’s.
