The one place I worked that tried to do this, the developers mostly ended up doing things easy to measure. Turns out it's super-easy to measure views and shares so content marketing it is! Not exactly a good use of our particular abilities but it seemed to make everyone (who was pushing the OKRs) happy. Our real work could rarely be connected to any kind of OKR. Too hard to measure and, "this OKR thing seems cool, we should gather data for at least 2 years on X, Y, and Z for a baseline averaged across projects so we can create OKRs to improve them" didn't fly, obviously. So. Youtube videos and blog posts it was.
