Six Sigma Green Belt Prep - Master DMAIC. Pass your Green Belt.
Focused, exam-style practice for the Lean Six Sigma Green Belt certification. Hundreds of questions mapped to the full DMAIC body of knowledge, clear explanations, and a timed mock exam so you walk in confident.
WHAT'S INSIDE
- Questions across the entire DMAIC cycle - Define, Measure, Analyze, Improve, and Control.
- Statistics made clear - hypothesis testing, normal distribution, process capability (Cp/Cpk), and measurement system analysis explained in plain language.
- Lean tools - value stream mapping, 5S, waste (DOWNTIME), Kanban, and Kaizen.
- Full timed mock exam that mirrors the real certification format, with a domain-by-domain score report.
- Every answer explained so you learn the "why," not just the "what."
- Track your accuracy by phase and target your weak spots.
TOPICS COVERED
Define (project charter, VOC, SIPOC, CTQ), Measure (data types, MSA, process capability), Analyze (root cause, hypothesis testing, regression), Improve (DOE, pilots, FMEA), Control (SPC, control charts, control plans), and core Lean concepts.
HOW IT WORKS
Answer 5 practice questions free every day. Upgrade to Pro to unlock unlimited questions, the full timed mock exam, and all reference material - available as an optional auto-renewing subscription or a one-time purchase through Google Play. Manage or cancel anytime in your Google Play account settings.
