There really are some metrics that are strategic. But when your manager is asked to have 20 OKRs just because your manager has to have 20 OKRs and then you get asked to have 20 OKRs that is a distraction.
(In terms of strategy there might be one thing or three things you REALLY need to do.)
At one place I worked I was expected to create OKRs for my own personal and professional development and I felt offended by it because it was out of phase with my own needs.
Today I do a lot for personal and professional development and it is highly strategic, it's motivated by being better at what I do for work but also about getting the social opportunities I want and where I think technology is going over the next ten years.
Because it is strategic I am continuously finding that a project I started a year ago has given me exactly the resource I need right now for a situation I had no idea I'd be in.
Like hell I need to fill out a form in some artificial format for my boss about it.
