One of Nielsen's famous heuristics is "The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms".
With no disrespect to Mr Nielsen, of course, I can think of no less familiar a term with the people I work with than "heuristic."
I'm trying to introduce heuristic evaluations as a tool in our toolkit, but no one is going to have the faintest idea what I'm talking about without more explanation.
The only idea I keep coming back to is "Usability checklist".
