Free LSSYB: Lean Six Sigma Yellow Belt Exam Questions and Answers
Lean Six Sigma Yellow Belt is one of the Six Sigma belt certifications covered here. There is no single Six Sigma awarding body, and that is the most useful thing to know before paying for anything. A Green Belt from ASQ, from IASSC and from a training company are three different credentials: ASQ requires documented experience and, for Black Belt, completed projects backed by signed affidavits, while IASSC tests knowledge only, with no prerequisite at all, and publishes a 70% pass mark that ASQ withholds. What genuinely is common to all of them is DMAIC — define, measure, analyse, improve, control — the cycle every credible belt programme is built on. Check which body issued a certificate before treating it as equivalent to another.
