Ask HN: Does anyone have experience transitioning to use OKRs?

OKRs (Objectives and Key Results) have been used at Google since "John Doerr originally presented OKRs to Google’s leadership in 1999 when Google was less than a year old, and they’ve been in use ever since." [1.] How did the transition go from not using OKRs since the nascent years of your company to then using OKRs to guide and to uphold decisions? I'm curious about how OKRs changed your approach to work and your company and how positive or negative the impact was? 1.
