This document discusses communication and strategies to avoid communication breakdown. It begins by defining communication and noting that the goal is clear understanding to build relationships. It then discusses three models of communication: linear, interactive, and transactional. Linear communication is one-way without feedback, interactive includes feedback between parties, and transactional is circular with parties exchanging roles. The document also identifies potential barriers to communication like physical, psychological, cultural and linguistic factors. These barriers can cause breakdowns in understanding. Finally, it discusses strategies to minimize breakdowns like actively listening, asking questions, being aware of tone and body language, and adapting to different communication styles.
