Push communication sends information to specific recipients who need it, such as emails, memos, and reports, without confirming that it was received or understood. Pull communication places information in a central location for recipients to access when they need it, such as intranet sites, knowledge repositories, and shared drives. Interactive communication is a real-time, multi-directional exchange between two or more parties, such as meetings, phone calls, and video conferences. Interactive communication is most effective for complex or sensitive issues.
