The document summarizes research from the Plank Center for Leadership in Public Relations on models of excellent leadership in communication management. The research developed a six-dimension model of leadership including vision, ethics, collaboration, communication abilities, global perspective, and continuous learning. Surveys of over 4,000 practitioners found the most important qualities of leaders were vision, ethics, and collaboration. Leaders reported developing most through on-the-job experiences, mentors, and formal education. The research also found some differences in perceptions of leadership between gender and organization size.
