I feel seen, but agree, I would have used "identifying and prioritizing work"...
...but I will admit, it does sometimes feel inventive, and when I describe what I do, it does feel... inventive... in some sense. Particularly "no one in the org asked me to..."... instead it's almost always, identifying and getting ahead of needs, or, responding to overlooked friction/problems, etc...
At least you are getting a lot of fun for it! I have always wanted to join the platform team in my org...
