This document outlines several barriers to effective communication, including semantic barriers due to ambiguous language, organizational barriers from rigid structures and status relationships, and interpersonal barriers stemming from differences between communicators. It also discusses individual barriers like inattention and defensiveness, as well as cross-cultural barriers from differences in language, values, and nonverbal expression between groups. Some suggestions are provided for overcoming these barriers, such as fostering good relationships, using clear and focused language, and planning messages carefully.
