Effective communication is important for managers to plan, organize, lead and control organizations. Communication helps managers perform their jobs and communicate plans to implement them. It is also important for motivating employees, increasing productivity, and allowing employees to submit work reports and suggestions. There are several types of communication including intrapersonal (within oneself), interpersonal (between two people), intragroup (within a group), and intergroup (between groups). Each type plays an important role in developing effective organizations.
