In its simplest terms, internal com

In its simplest terms, internal communication is communication within an organization. It encompasses both "official" communication -- memos, guidelines, policies and procedures, etc. -- and the unofficial communication that goes on among and between the staff members of all organizations -- the exchange of ideas and opinions, the development of personal relationships, and the proverbial conversation around the water cooler. It goes in all directions among line staff (those who do the specific work of the organization and work directly with the target population), administrators, supervisors, clerical and support staff, volunteers, and, perhaps, even the Board of Directors.
