@sam_alaimo I’ve worked on monthly and quarterly OKR’s with UX teams. Working on the 70% attainment goal throughout your sub-goals can be tough when you only have a few data driven or trackable in-product events or interactions. The Heart Framework does a good job of breaking out Signals and Goals and looks pretty cool (glad you mentioned it!)
If you don’t have a way to quantify your goals - then make one!
What you might try is a quarterly survey (maybe use Typeform) to the segment of users that have been a part of new tests, sometimes just straight up asking “how it was” will get you the best kind of answers and information that you can’t get staring at a screen full of analytics. If you’re using intercom you could also hit active users in this segment and display the thumbs up / thumbs down option they provide.
