Oh, there is a real Kasia. Although she's a person of many talents, I would be genuinely surprised if she spent evenings studying Japanese management methods.

The solution she designed, however, is as if she already knew all of that part of the MBA program :)

Which shows how significant parts of these methods have roots in basic awareness and perceptiveness to how the work gets done. Lean/Agile only codified some of these good practices. Unfortunately, they also petrified a lot of specific techniques. But that's another story.
