I’m just imagining going up to somebody in the c-suite and telling them what team I work for and what I do. I guarantee they would have no idea we exist. I once sat next to the manager who is three levels above me at a lunch meeting. She had zero idea who my team was or what we did.
I think Leo de Moura was at Microsoft at the time when he was developing the Lean proof assistant. He once commented that he was fairly sure the CEO did not know the language existed or that it was being developed within MS. I found that pretty funny, and probably entirely accurate!
