This document discusses the importance of audience recognition in business communication. It defines audience as the individual or group that will read or listen to a memo, letter, or report. To ensure effective communication, writers should consider who their audience is, what their level of understanding is, and what their position is relative to the writer. Depending on the audience's technical knowledge, they may be categorized as high-tech, low-tech, or lay audiences. High-tech audiences share the writer's expertise; low-tech audiences have some knowledge but may need explanations; and lay audiences have no background. When writing for multiple audiences, the document advises providing background knowledge, references, and explanations of jargon and acronyms.
