Five belts, one continuous curriculum
White through Master Black Belt in twenty-eight lessons, each level including the shared prerequisites the advanced work depends on. Buy the level you need; the ones below it come with it.
Depth that carries to Black Belt
Design of experiments, measurement systems and reliability, regression and inference, constraint management, and design for Six Sigma -- taught at the depth the advanced belts assume, not summarised.
Every option explained, and the trap named
Answering a question shows why the key is right and why each distractor is wrong, and names the misreading the question is built on.
Every stated objective is tested
Each lesson publishes its learning objectives, and every objective on a lesson with a quiz has at least one question written against it. Nothing is listed and left untested.
