This has always been my beef with OKRs in the software industry. Most shops are at least pretending to be agile-ish. And this means that a random IC dev is pulling tickets from the backlog and doing them. They're not going to be personally responsible for "improving the response time of the FizzBuzz server by 22.3%" or anything like that. No - the product manager tells the team on what they'll be working, the work gets broken down into parts, and they take what's available when they come up for air. OKRs should never be handled at a level more granular than a scrum team, or equivalent.
