That's not really how it's done in practice though, fwiw. Large tech firms mostly try to quantify "impact" and that can mean a lot of things. You could have very large name recognition by doing a lot of outreach, like talks. Being a bit reductive, that's like promoting someone for their sense of celebrity. Then there's folks who save quantifiable dollars or improve some process by some nominal percentage of $success_metric for their impact. Wrangling a large project usually is pretty arbitrary and not on a single engineer - in fact, most of them are committee based.
