BUILT FOR THE EXAM
Content is organized the way Green Belt exams are: the five phases of DMAIC, Lean tools like 5S, value stream mapping, kanban and takt time, and the descriptive and inferential statistics that show up on every test. An Exam Info section explains the format and links to the official certifying bodies.

WHO IT'S FOR
Candidates preparing for ASQ CSSGB, IASSC ICGB, and employer or training-provider Green Belt exams, and anyone who wants a serious, structured refresher on Lean Six Sigma.

This app is independent study material. It is not affiliated with, endorsed by, or certified by ASQ, IASSC, or any other certifying body. All questions are original and are not real exam questions.
