I do think it's worth remembering that John Doerr's implementation of OKRs at Intel actually did include binary goals. I remember reading the book and seeing "complete design and begin fabrication of chip X by Y date" (I'm paraphrasing because I don't feel like going through the book to find it). Yes, the higher-level objective was "establish Intel as the top chip maker" but that, by necessity, included "actually make the chip."
