Six Sigma Green Belt: CSSGB

Study for the ASQ Certified Six Sigma Green Belt (CSSGB) exam the way a Green Belt project actually runs: Define, Measure, Analyze, Improve, Control. The app lays the 2022 Body of Knowledge out as a DMAIC roadmap, checks you phase by phase, and shows how ready you are for the exam as a whole.

YOUR DMAIC ROADMAP
• Every phase of the exam on one roadmap, in the order a project moves through it, each with its weight on the exam
• A phase check for every phase: a scored set with an explanation after each answer
• An exam-readiness score weighted the way the exam is weighted, so a strong Measure counts for more than a strong overview
• A next step that always points at the phase that needs you most
• Tell it where you are starting (new to Six Sigma, mid-project, or refreshing) and when your exam is, and the roadmap starts you in the right place with a countdown

GREEN BELT CALCULATOR (FREE)
Roughly a third of the CSSGB exam is arithmetic. The calculator works each problem the way the exam expects and shows the working, and every phase on the roadmap links to the tool it uses:
• DPMO and sigma level, with the 1.5 sigma shift
• Process capability: Cp, Cpk, Pp, Ppk, Cpm and expected PPM
• Control limits for X-bar R, I-MR, p, np, c and u charts
• Rolled throughput yield, FMEA risk priority number, takt time and cycle efficiency

WHAT THE EXAM COVERS
• Six Sigma and the Organization: lean, value stream mapping, DfSS, FMEA
• Define: project charters, SIPOC, voice of the customer, Kano, team dynamics
• Measure: probability, distributions, MSA and gauge R&R, process capability
• Analyze: hypothesis testing, regression, ANOVA, chi-square, root cause analysis
• Improve: design of experiments, kaizen, SMED, 5S, poka-yoke
• Control: SPC, control charts, control plans, TPM, visual factory

PRACTICE AND LIBRARY
• Multiple-choice questions, each explaining why the answer is right and why the tempting choice is wrong
• True/false drills built from the misconceptions that cost candidates points
• Term matching, flashcards and a searchable formula sheet with worked examples
• A missed-question deck that holds everything you got wrong

Start with a free roadmap warm-up across all six phases. Premium unlocks every phase check, question, flashcard, glossary term and formula. Your progress stays on your device: no account, no internet connection needed.
