Communication is an essential skill for project managers, as they spend 80% of their time communicating. Effective communication requires considering factors like urgency, technology availability, ease of use, and the project environment. Communication techniques may include emails, presentations, meetings, and social media depending on the sensitivity of information and project needs. Developing strong communication competence through clarity, relationships, and leadership is important. Feedback and nonverbal communication such as body language and eye contact also support effective project communication.
