Managers plan, organize, lead, and control the work of others to help achieve organizational goals. They oversee the four functions of management - planning, organizing, controlling, and leading. Managers require conceptual skills like analytical thinking, technical skills like computer skills, and human skills like communication. Organizational behavior is the study of human behavior in organizational settings, how employee behavior and attitudes impact the organization, and how to improve performance. It draws from psychology, sociology, communications, and other disciplines to understand workplace behavior and design effective organizations. Understanding organizational behavior helps managers improve organizational effectiveness and efficiency.
