The EXIN LSSA Six Sigma Green Belt study guide has 4 sections and about 1,458 words.
01Define Phase
The Define phase tests your ability to turn a business pain into a bounded, data-ready project. The exam focuses on the charter, problem and goal statements, scope, VOC-to-CTQ translation, stakeholders, and readiness for the Measure gate. A charter contains the business case, problem statement, goal, scope, team, milestones, constraints, and expected benefit. The problem statement states what, where, when, and magnitude, with a baseline.
353 words, about 2 min02Measure Phase
Measure establishes a trustworthy baseline. The exam tests operational definitions, data collection, measurement system analysis, process stability, capability, and sampling. The central rule is simple: do not calculate capability from data you do not trust. Define each data field operationally: what is measured, how, by whom, when, and at what resolution.
364 words, about 2 min03Analyze Phase
Analyze tests causal hypotheses and quantifies relationships. The exam asks you to choose the right graphical or statistical tool, check assumptions, and separate statistical significance from practical importance. Use process maps, fishbone diagrams, 5 Whys, and FMEA to generate hypotheses, then verify them with data. A fishbone is not proof of a root cause.
366 words, about 2 min04Improve and Control Phases
Improve selects and tests solutions against verified causes; Control locks the gain into daily work. The exam tests solution selection, pilots, DOE basics, Lean countermeasures, control plans, SPC chart choice, and handover. Link every solution to a verified root cause. Prioritize by impact, effort, risk, and reversibility; update FMEA before implementation.
