It is an official way of communicating. A formal communication channel transmits information such as the goals, policies and procedures of an organization. Messages in this type of communication channel follow a chain of command. This means information flows from a manager to his subordinates and they in turn pass on the information to the next level of staff. Some examples include company newsletters, business plans, instructions, annual reports, agreements, company-wide communications, board presentations etc.

(ii) Informal channels: It is also an official way of communicating, with somewhat relaxed norms. There may not be a need for a chain of command or hierarchy in this kind of communication. There will be immense official communication where such hierarchy or command is not needed, but they happen within the official framework. Some examples will include conversations on the work floor addressing queries of team members, lunch time conversations, many of the emails where formal command is not needed such as someone is seeking some quick information etc. Under the official environment, both formal and informal channels are used as needed.

(iii) Unofficial channels: There exists an unofficial mode of communication as well. The employees communicate outside work environment on topics not related to work. General social, sports, political and personal communication are unofficial channels. But a manager needs to be aware about the existence of such a channel and information flowing in them. Many times rumours and gossips also provide very important information which otherwise will not be available.
