This document discusses interpersonal communication and identifies five common methods: written, telecommunications, third party, face-to-face, and gestural. It notes that effective communication is key for employees at all levels as they typically spend 70-90% of their time communicating. The five methods are then described in more detail, with written communication highlighted as ensuring everyone receives the same message but being less effective than face-to-face or telecommunications which allow for feedback. Perceptions, expectations, and building interpersonal skills are also covered.
