[header] How to know your audience [title] Use words and phrases your audience understands. [step] Instead of using an acronym or technical jargon, use a relevant word or phrase that provides the same meaning. For example, business people like to use sme's (pronounced like " smees ") to describe a person who is a subject matter expert. 
The time you save by saying " smees " is lost when it causes an unfamiliar listener to try to figure out what you mean. Just say " subject matter expert " or " expert " or " business owner " or something to describe the same thing.
