From a grammar professor: Quality may be the most abused and overused word in business English. The word is a noun, and means a characteristic or a degree of excellence. Don’t use quality as an adjective, as in a quality product — leave that sort of cant to advertising copywriters. Use well made, good, useful, something like that. Never use quality as an adverb, as in a quality-built product. Perhaps the best advice is: never use quality.
I’m not quite as picky, but dang, at least tell me what kind of quality (noun) it is. If you tell me you have a quality company (as the high-quality publisher Liquid Silver Books recently did on Dear Author), I have the option to think it’s poor-quality.
I hate this one. And I think it’s too late. It has drifted into common usage, thanks to “quality GM trucks and cars” (hardeharhar) and other schlocky admeisters.
