Superb!
And I was sure Gene Kim's Phoenix was original.
Well, if you liked it - you will definitely find The Goal very thought-provoking without cheesy scrum examples.
I liked it a lot; it reads like a novel with some serious call in there - done with a goal in mind, every enterprise has a chance to succeed with new & ongoing initiatives.

I haven't read a compelling management book in years; I think the last one was written by Lacoca on his career. Other than that it is difficult to find something useful these days.
