What’s on the Six Sigma Green Belt cheat sheet
- Six Sigma & the Organization (11%) — sigma level, DPMO, the 1.5σ shift, lean's 8 wastes, and DMAIC vs DMADV.
- Define (20%) — project charter, VOC and CTQ, SIPOC, the Kano model, and team stages — one of the two largest sections.
- Measure (20%) — data types, distributions, Gage R&R (MSA), and the Cp/Cpk capability formulas — the most quantitative section.
- Analyze (18%) — fishbone (6 Ms), 5 Whys, Pareto, hypothesis testing, Type I/II error, and FMEA with RPN.
- Improve (16%) — design of experiments basics and lean tools — 5S, kaizen, poka-yoke, and kanban.
- Control (15%) — statistical process control, control charts, common vs special cause, and control plans.
How to use it in your final week
- Memorize the sigma-to-DPMO anchors cold — 3σ ≈ 66,807 DPMO, 4σ ≈ 6,210, and a Six Sigma process = 3.4 DPMO after the 1.5σ long-term shift.
- Front-load Define and Measure — together they are 40% of the scored questions (about 20 each), and Measure is where the Cp/Cpk and yield math lives.
- Drill the two capability formulas until they are automatic: Cp = (USL − LSL) ÷ 6σ, and Cpk = min[(USL − μ), (μ − LSL)] ÷ 3σ, remembering Cpk ≤ Cp always.
- Pair each review pass with a short timed practice set so the 4-hour-18-minute clock feels routine, and tab your bound reference the way you will use it on the open-book exam.

Six Sigma Green Belt cheat sheet FAQ
Yes — the Six Sigma Green Belt cheat sheet downloads as a PDF with no account and no sign-up. It sits alongside Career Employer's free CSSGB practice test, study guide, and flashcards, so your whole review layer costs nothing.
It condenses the highest-yield ASQ CSSGB facts into a quick reference: the DMAIC roadmap, the DPMO and sigma-level table, the Cp and Cpk capability formulas, control-chart rules, and the section weights. Everything is organized around the six body-of-knowledge sections so you can scan by exam phase.
It is built from ASQ's current CSSGB Body of Knowledge and quality resources, and we review it against ASQ's published outline regularly. Treat any dollar figure or fee on the sheet as a dated anchor and confirm the current number on asq.org before you apply.
No — the sheet is a cram and last-week review aid, not a full course. The ASQ exam is open-book but time-pressured, so you still need to work DMAIC scenarios and practice DPMO, Cp, and Cpk calculations. Use the sheet to lock in facts and the practice test to prove you can apply them.
