There's a category of question on my Lean Six Sigma Green Belt Certification practice tests that I'm consistently missing and I can't figure out what I'm misunderstanding.
The questions are about lean. Here's the type of question that trips me up: they give me a scenario and ask what the right action is, and I usually narrow it down to 2 answers — then pick the wrong one.
I think my issue is I'm applying the general rule but not accounting for the exception. Can anyone point me to a good explanation of when the standard rule doesn't apply for lean?
I've looked at "lean manufacturing" study materials but they explain the concept at the surface level. I need the deeper "why" behind it.
Any specific resources, videos, or even just a plain English explanation would be genuinely helpful. Exam is in 3 weeks.
Same boat a few months ago. Here's what I'd tell myself:
The LEAN exam is more concept-focused than the study guides suggest. They test whether you understand lean manufacturing, not just whether you can define it.
My tip: when you see a scenario question, mentally walk through it step by step before looking at the answers. The wrong answers are designed to catch people who jump to conclusions.
Good luck — the fact that you're doing this level of prep means you're going to be fine.
Quick data point: I spent 6 weeks studying, 2-2 hours a day, and passed with a 75%.
The section on lean took me the longest to feel confident about. Eventually I just drilled practice questions until I could answer them without hesitation.
What testing center did you end up booking? Some of them have much shorter wait times than others right now.
