I have a pretty extensive personal system partially based on OKRs but I find the key element is doing the exercise as a group and having accountability partners.
I’d like to see this added to the system. At my company, every goal has a “POC” – point of contact aka “owner” or “partner”. I think you should add a partner to each goal – a person who will rate you on the objective. The objectives are what matter. e.g. if you hit 6 hrs time with gf, but she still thinks you are rubbish , you haven’t made any progress on the “strengthen relationships with gf” objective.
