What I guess I'm saying is that it's insanely difficult to come up with good OKR's and so many good things aren't measurable, while the fans of OKR's don't seem to want to take this into account.

Whatever alternative methods (judgement of managers) is up for debate though, I didn't say I had a good one. Just that OKR's in my mind are a waste of time for the most part, especially when you make the whole organization do them.

And look at products like Facebook, they seem to be built solely on OKR's.
