So, yes, they definitely can game it by focusing on short term unsustainable wins and ignoring all medium and long term negative impacts. Push the AB testing games to their limits, like running the same text 5 times with minor "improvements", so that the statistical metrics no longer apply. Dark patterns that cause long term user value to drop but drives some short term revenue. And so on. Then you get the more fun ones like stealing work from other departments without giving them credit. They eat the R&D cost and you get the revenue win. A good middle manager will even spin it so it looks like their team did the R&D as well.
That said, it all works fairly well when you've got a monopoly in the area (ie: search and ads for Google) but in those cases most everything works fairly well.
This is just fine, but it's not enough.
The purpose of writing a proper mission and vision is to say something about how. There should be some coherent strategic guidance, some notion of where the company is and/or wants to be in the marketplace or in customers' minds, and so on and so forth.
If you have that (and it's actually backed up by reality), then the OKRs emerge organically across the portfolio of investments the company is pursuing. Land N more deals with this existing customer segment, experiment with new features in pursuit of that other customer segment, staff a team to ensure customers aren't lost for reason X or Y, etc.
The real magic, of course, is that every person in the company can then make a clear statement about how they're contributing to the broader mission and vision of the corporation. When it all lines up, it really is a beautiful symphony of capitalism.
In my experience I’m left scratching my head when it cures time to write my OKRs since as an IC, who doesn’t get to choose what I work on or what gets released, everything comes down to essentially “do my job more gooder”.
Maybe I’m just bad it or my managers were bad at guiding me, but every OKR I’ve written was essentially bullshit and at performance review time my manager sat down with me and we bullshitted how they were achieved so I could keep my job. It’s what everyone did. No one ever did not achieve a goal. How could I write a measurable goal that contributed to revenue if I had no control over anything but my own work? I can’t say “release N features” because I can’t control if I’ll work on N features that actually get released. And so on.
I’m just happy OKRs are firmly in my rear view mirror now.
This is the root of where every company I’ve worked for gets OKRs wrong. They always have some flowery statement for mission and vision and build their goals around that. However in the day to day work when decisions are made it becomes apparent that the mission is to make money and the vision is to make more money. And that’s how my OKRs always become divorced from reality, having been derived from the flowery bullshit that rolls downhill.
