Thoughts on OKRs
Every time I've seen it tried (over and over again in the span of a 30-year career), the "goals" are based on whatever the priority/flavor-of-the month happens to be when goal-setting is announced.  I've never seen those priorities last an entire year, but I have been called to account for why I didn't personally meet the goals that I was pressured into setting "for myself" even though the priorities shifted over the course of the year.
