Successful communication is a key issue in the business environment but before a manager or employee can start to improve his/her communication skills it is important to first look at the functions of communication in a business.
Not one of these functions should be seen as more important than the others. Almost every communication interaction that takes place in a group or organisation performs one or more of these four functions.
Communication can flow vertically or laterally (horizontally).
Communication is often necessary to save time and facilitate coordination.
