Output also doesn't capture 'enabling' functions: as a researcher I love to help others get to their goals, I love working on tricky problems and using my know-how to feel needed. I think I'm not alone in that.
Unfortunately that means that on paper, I have zero output while the people I help have all the output. Especially in computing/data science it's easy to fall into this trap; it takes a daily check-in to make sure that I'm working on the stuff that counts for me and my group.
Also accumulated know-how can be partially visible by writing out docs, patents, guides and the like. Definitely not enough but can increase visibility.
