It doesn't seem like a terribly hard test. But that's as someone who has (quiet now) an MBA who did a 1:1 project for an operations management professor and graduated high in their class albeit a long time ago. So don't read a lot into my assessment.

The Kanban answer I found especially interesting. The equivocation on the one answer is exactly the one I would have equivocated on. (Well, yes, that's the idea but it has to be done correctly.)

I'd also observe that operations management/engineering is a lot closer to other types of engineering than things like organizational behavior are so writing this off as just an MBA thing is pretty complacent.
