PURPOSE Choosing the right communication method saves time and reduces confusion. USE EMAIL FOR Formal updates, decisions, documentation, external communication, and information people may need later. USE CHAT FOR Quick questions, lightweight coordination, and informal updates. USE A CALL FOR Time-sensitive discussion, complex clarification, or topics that are easier to resolve verbally. USE A MEETING FOR Decisions, planning, collaboration, conflict resolution, or topics requiring multiple people at the same time. BEST PRACTICE Match the tool to the urgency, complexity, audience, and need for a record.
