Communication is essential for achieving managerial and organizational effectiveness. Good communication helps employees become more involved in their work and helps them develop a better understanding of their jobs. Clear, precise and timely communication of information also prevents the occurrence of organizational problems. Without communication, employees will not be aware of what their coworkers are doing, will not have any idea about what their goals are, and will not be able to assess their performance. Managers will not be able to give instructions to their subordinates and management will not receive the information it requires to develop plans and take decisions, hence communication acts as a nervous system for any organization.
