Lean and measurement tools

SIPOC, CTQ, the eight wastes, measurement system analysis, process capability and control plans: the tools the Yellow Belt exam asks you to recognise and apply.

Book and sit your exam

How to redeem your voucher, book with PeopleCert and get your computer, room and ID ready for the online exam.

You will know when you are ready

Every quiz in this simulator is marked against the same 70% the real exam uses, so your score tells you straight away which side of the line you are on.

There is no limit on attempts, and every run draws a different set of questions in a different order, so the simulator does not run out before you do.
