My favorite is the times when I have dived in to fix performance of the system, found the place where I or a team mate left in a terribly unnecessary loop or increased complexity, quickly fix that and report back the great success in improving performance! Great indicator there for management.

I think the person/team following such a path does deserve accolades but if their ego blocks them from admitting honestly how difficult the work was, others will sense (maybe not management) the dishonesty sooner or later and problems will eventually develop.

I always give my team mates accolades and offer them excuses when they've messed up: "we were really busy that week", "its easy to forget to bump the minor version", "that manual testing work is tough". If they choose to ignore the offered excuse and go silent with their ego I think it stands out sorely over time. If they accept it then we all know what we have to improve on next time.
